MIL-DTL-38999 Series I, II, III Connectors

MIL-DTL-38999 Speciﬁcations

After preloading to 3 pounds maximum, the force shall be applied at a rate of approximately 1 pound per second and maintained at full load for 5-10

seconds. No damage to contacts or insert shall result nor shall the contacts be dislocated from their normal position in the connector more than 0.012 inch

under the given load. Failure to meet these requirements shall be cause for rejection.

The following excerpts are some of the parameter requirements of the MIL-DTL-3899 Specication.

For qualication testing, mating halves shall be coupled and uncoupled, measuring the torques necessary.The torques required to couple and uncouple

mating connector halves shall fall within the limits specications as follows:

Connector halves shall be mated and unmated 250 times for Series II with ground ngers and 500 times for Series I and III at a rate not exceeding 300 cycles

per hour. The test may be performed by hand or by mechanical means, but the coupling ring shall be operated as in normal service. Failure to complete this

test because of mechanical malfunction shall be cause for rejection.

An insulation resistance test shall be performed on unmated connectors in accordance with MIL-STD-202, Method 302, Test condition B. Measurement shall

be made between three pairs of adjacent contacts and the shell. Failure to meet the minimum requirement of 50,000 megohms for Classes E, P, F, R, and

T shall be cause for rejection.

Wired, mated connectors shall be subjected to the vibration test of MIL-STD-202, Method 214, Test Condition II, except that the duration shall be one hour

in each plane. Receptacles shall be mounted on the vibration xture by normal means. All contacts shall be wired in a series circuit and 100-500 millamperes

of current shall be allowed to ow through the series circuit during vibration. Suitable means shall be employed to monitor the current ow and to indicate

any discontinuity of more than 1 microsecond. The wire bundle shall be damped to the nonvibrating points at least 8 inches from the rear of the connector.

Current discontinuity of 1 microsecond or more, disengagement of the mated connectors, evidence of cracking, breaking, or loosening of parts shall

be cause for rejection.

Wired mated connectors shall be subjected to one shock in each direction in each of three mutually perpendicular axes. The pulse shall be approximate half

sine wave of 300g ± 15% magnitude with a duration of 3 ± 1 milliseconds. Receptacles shall be mounted on a shock xture by normal means. All contacts

shall be wired in a series circuit and 100-150 ma. of current shall ow through the series circuit during shock. Suitable means shall be employed to monitor

the current ow and to indicate any discontinuity of more than 1 microsecond. The wire bundle shall be clamped to xed points at feast 8 inches from the

rear of the connector, Current discontinuity of 1 microsecond or more, disengagement of the mated connectors, evidence of cracking, breaking, or loosening

of parts shall be cause for rejection.

Mated connectors shall be placed in a container of water at approximately 20ºC and placed in an altitude chamber. All wire ends shall be located within the

chamber and exposed to the chamber atmosphere, but not submerged. The exposed wire ends shall not be sealed. A quantity of salt, 5 percent by weight,

shall be added to make the water conductive. The chamber pressure shall then be reduced to approximately one inch of mercury and maintained for thirty

minutes. The chamber pressure shall then be slowly returned to atmospheric. This shall be considered one cycle. Two additional cycles shall be performed. At

the end of the last cycle, while the mated connectors are still submerged, the Insulation Resistance Test (room temperature), and the High Potential Test (sea

level voltages) shall be performed upon the same circuits. Failure to meet an insulation resistance minimum of 2,000 megohms or any evidence of dielectric

breakdown or -ashover shall be cause for rejection.

Unmated connectors shall be immersed fully in the applicable uid specied below for 20 hours. After removal from the uid, each connector shall

remain for one hour in free air at room temperature.

a.) Jet fuel JP-4 to MIL-J-5624 b.) Aircraft lubricating oil to MIL-L-9236

Unmated connectors and individual contact samples shall be subjected to the soft spray of MIL-STD-202, Method 101, Test Condition 8 (tin plated, Class Y

receptacles-24 hours). Immediately after exposure, the surfaces of the specimens shall be thoroughly washed in tap water and dried in a circulatory oven at

a temperature of 38 ±3ºC (100ºF) for a period of approximately 12 hours. Any exposure of basis metal as a result of this test, shall be cause for rejection.

(Series I and 11, nish B; Series III, class W). The wired assembled plugs and receptacles shall be mated and unmated 50 cycles at a rate of 300 cycles per hour

maximum. The mating and unmating shall be accomplished so that the plug and receptacle are completely separated during each cycle. The connectors shall

then be subjected to the salt spray test in accordance with method 1001 of MIL-STD- 1344. The connectors shall be tested for 452 hours mated followed by

48 hours unmated. After the salt spray exposure the remaining number of durability cycles specied in 4.7.7 shall be completed.

Unmated receptacles shall be subjected to 10 cycles of thermal shock in the following manner:

The receptacle shall be suspended for 10 + 1 - 0 minutes in the center of a cold water both with a volume of approximately one cubic foot. No

dimension of the bath shall be less than 10 inches. The water temperature shall not exceed 4ºC (39.20ºF)

The receptacle shall be suspended for 10 1 - 0 minutes in the center of a hot water bath with a volume of approximately one cubic foot. No

dimension of the bath shall be less than 10 inches. The water temperature shall be not less than 94ºC (201ºF).

The time of transfer from one bath to the other shall not exceed 5 seconds. At the end of the tenth cycle, the receptacle shall have the excess moisture shaken

off and shall then be dried in a forced air oven at 66±5˚C for 15 ±1 minutes. Any evidence of damage resulting from this test shall be cause for rejection.

Product Safety and Warranty

1. MATERIAL CONTENT AND PHYSICAL

FORM

Electrical connectors do not usually contain

hazardous materials.

Electrical connectors and individual com-

ponents do not release or otherwise result

in exposure to hazardous chemicals under

normal conditions of use and fall under

the denition of “Article,” under the

Hazard Communication Standard, 29 CFR

1910.1200, and are not considered hazard-

ous materials.

Solder and uxes can be hazardous if inhaled

or absorbed through the skin and should

only be used as recommended by the manu-

facturer. Please consult your solder and ux

manufacturer for more specic application

recommendations.

2. FIRE CHARACTERISTICS AND ELECTRIC

SHOCK HAZARD

There is no re hazard when the connector is

correctly wired and used within the specied

parameters. Incorrect wiring or assembly of

the connector or careless use of metal tools

or conductive uids, or transit damage to

any of the component parts may cause elec-

tric shock or burns. Live circuits must not be

broken by separating mated connectors as

this may cause arcing, ionization and burn-

ing. Heat dissipation is greater at maximum

resistance in a circuit. Hot spots may occur

when resistance is raised locally by damage,

e.g. cracked or deformed contacts, broken

strands of wire. Local overheating may also

result from the use of the incorrect appli-

cation tools or from poor quality soldering

or slack screw terminals. Overheating may

occur if the ratings in the product Data

Sheet/Catalog are exceeded and can cause

breakdown of insulation and hence electric

shock. If heating is allowed to continue it

intensies by further increasing the local

resistance through loss of temper of spring

contacts, formation of oxide lm on contacts

and wires and leakage currents through car-

bonization of insulation and tracking paths.

Fire can then result in the presence of com-

bustible materials and this may release nox-

ious fumes. Overheating may not be visually

apparent. Burns may result from touching

overheated components.

3. HANDLING

Care must be taken to avoid damage

to any component parts of electrical connec-

tors during installation and use. Although

there are normally no sharp edges, care

must be taken when handling certain com-

ponents to avoid injury to ngers. Always

wear safety glasses to avoid potential injury

to eyes during cleaning, soldering, ber

preparation, etc.

Electrical connectors may be damaged

in transit to the customers, and damage

may result in creation of hazards. Products

should therefore be examined prior to instal-

lation/use and rejected if found to be dam-

aged. Proper lifting techniques shall be used

for handling shipping cartons.

4. DISPOSAL

Please recycle, reclaim or dispose of connec-

tors and individual components in accor-

dance with local, state and federal laws.

Incineration of certain materials may release

noxious or even toxic fumes..

5. APPLICATION

Connectors with exposed contacts should

not be selected for use on the current sup-

ply side of an electrical circuit, because an

electric shock could result from touching

exposed contacts on an unmated connector.

Voltages in excess of 30 V ac or 42.5 V dc are

potentially hazardous and care should be

taken to ensure that such voltages cannot

be transmitted in any way to exposed metal

parts of the connector body. The connector

and wiring should be checked, before mak-

ing live, to have no damage to metal parts

or insulators, no solder blobs, loose strands,

conducting lubricants, swarf, or any other

undesired conducting particles. Circuit resis-

tance and continuity check should be made

to make certain that there are no high resis-

tance joints or spurious conducting paths.

Always use the specied application tools,

cleaning materials and assembly instructions

documented in the Data Sheet/Catalog. Do

not permit untrained personnel to wire,

ITT Cannon

ITT is a focused multi-industrial company that designs and man-

ufactures highly engineered critical components and customized

technology solutions. Our customers in the energy, transpor-

tation and industrial markets depend on us to solve their most

critical problems, and we focus on partnering with them to

nd solutions to their unique challenges. Founded in 1920, ITT

is headquartered in White Plains, N.Y., with employees in more

than 35 countries. The company has sales in approximately 125

countries and generated 2014 revenues of $2.7 billion.

Our connector portfolio remains the most extensive in the

industry, offering a reliable and cost effective range of inter-

connect solutions with the brands of Cannon, VEAM and BIW

Connector Systems. Continuous investment in technology and

research & development have enabled ITT to provide new, inno-

vative products and solutions to markets including:

• Automotive

• Computer & Consumer Electronics

• Industrial/Instrumentation

• Military & Aerospace

• Oil & Gas

• Telecommunications/Wireless Handheld Devices

• Transportation

When you specify a Cannon, VEAM or BIW Connector Systems

connector, you can rely on products that are designed, devel-

oped, and manufactured to the highest quality and reliability

standards. This tradition of excellence is based on ITT’s corpo-

rate culture of operating its businesses under the principles

of Six Sigma. At ITT, Six Sigma is not just a quality philosophy

but a complete corporate culture that drives the entire busi-

ness. Our Value Based Management and Value Based Product

Development systems are two cornerstones that allow for the

development of both leadership and product engineering prin-

ciples, ensuring our industry leading products are developed to

the accepted market driven lead times. These principles have

allowed ITT to become the market leader in all of our business

portfolios.

Six Sigma Manufacturing

ITT Cannon operates manufacturing facilities in the United

States, Germany, Italy, Mexico, China and Japan, all of which

have particular product area strengths allowing ITT to offer a

truly global footprint to our customers. Our facilities are world

class and accommodate full vertical integration utilizing the

latest manufacturing technologies including: automated and

robotic machining centers, Super Market manufacturing cells,

Kanban pull systems, and automated electrical, mechanical,

and optical test and inspection equipment. The combination of

our manufacturing strength and our advanced manufacturing

facilities allows ITT to offer products at market driven prices.

Our capabilities, especially in robotics, computerized precision

tooling, Kaizen Project Management, Six Sigma tools, and test-

ing, give ITT the most optimized global manufacturing

footprint in the interconnect industry.

The Custom Difference

As the industry leader in harsh environment interconnect appli-

cations, ITT’s world class engineering teams will work directly

with our customers to design and develop cost effective solu-

tions for their applications. In many cases we may modify one

of our standard designs to ensure a highly reliable solution

where timing is critical. Yet, in those cases where a complete

custom interconnect solution is required, ITT will work with

our customer’s Engineers to design an interconnect solution

which will be cost effective yet highly reliable. As professional

consultants, our Engineering teams will provide a thorough

systems and mechanical analysis of any proposed solution.

These analyses provide our customers with sophisticated elec-

trical signal and mechanical characterizations to determine

the best solution for their application.

RoHS Compliance Information

ITT has implemented a strict parts control plan for all ITT

electronics plants worldwide that allows the Cannon, VEAM,

and BIW Connector Systems product portfolios to meet the

requirements of the European Union Directive 2002/95/EC bet-

ter known as the Reduction of Hazardous Substances (RoHS)

initiative. As appropriate, specic Cannon, VEAM, and BIW

Connector Systems products may be ordered with an R prex

number which insures our customers will receive RoHS com-

pliant parts for their commercial electronics applications and

equipment. Since most RoHS hazardous substances center

around specic metal plating and lead solder coatings, ITT’s

products for RoHS compliance are available in the following

plating nishes: electroless nickel, stainless steel, anodize over

aluminum and gold plating. It should be noted that gold plat-

ing would be recommended as the replacement for tin-lead

solder when ordering board mount connectors.

Developed rst by Cannon in the 1960s, microminiature

connectors offer high performance and reliability with

exceptional versatility. Available in rectangular, circular

and strip congurations for countless applications, many

of our microminiature connectors meet or exceed applicable

requirements of the MIL-DTL-83513 specication.

RF Connectors

Since 1963, Cannon has provided connectors to the Microwave

and RF industry. The RF 50 & 75 Ohm product lines cover UHF

band through Ku band requirements. These connectors and cable

assemblies are available with a thread type, snap type, bayonet

type or slide on coupling method. The frequencies range from DC

to 18+ GHz.

D-Subminiature Connectors

Cannon invented D-Sub connectors in 1952. Our family of

D-Subs now includes combinations of signal, power and RF,

as well as severe service sealed connectors. Cannon D-Sub

are available with an extensive line of backshells and

accessories and are one of the most economical shielded

connector solutions available. Our D-Sub connectors are

qualied to the MIL-DTL- 24308 specication.

Transportation

We offer a range of sealed circular and rectangular connectors in

metal or plastic shells. These congurations include board to cable

or cable to cable/ bulkhead applications. Both signal and power

contacts can be combined in various layouts. All product lines within

the Transportation segment offer very low contact resistance and

deliver maximum signal integrity.

As a world leader in circular, lter and hermetic connectors, ITT

Cannon leverages its design and manufacturing expertise to t

virtually any application. Our expertise includes fast positive mating

for a wide range of military applications, as well as numerous sizes
