NOTES

1. For cautions for use, please read

“GENERAL APPLICATION

GUIDELINES”.

2. Because the NC relay is polarized, the

positive “+” and negative “–” connections

to the coil should be done as indicated on

the wiring diagram. If connected

incorrectly, it may malfunction or fail to

operate.

3. While NC relays can be used with any

transmission-wave current to their

operation, due to slight weakening of the

force of magnetic attraction, decreased

resistance to vibration and shock should

be taken into account.

5. Cautions for close proximity mounting

When using slim series in close proximity,

mount all relays facing the same

direction. Di󰀨erent mounting directions

may cause change in the relay

characteristics because NC relays are

polarized.

4. When designing top and bottom view

schematic diagrams, note that:

1) “Top view” wiring diagram is indicated

for the at series because terminals can

be seen from above.

2) “Bottom view” schematic diagram is

indicated for the vertical series because

terminals cannot be seen from above.

ACCESSORIES

• Socket

1) The vertical (slim) type with solder

terminals has a retainer, which enables

snap-in xing on chassis, panels, and

similar locations. Because the sockets for

both solder terminals and PC boards

rmly x the relay at the time of insertion,

once snapped in, spring clips are

unnecessary.

2) For the at type, pull up the hinged

clasps in the direction of the arrows

shown in the drawing after inserting the

relay.

GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE

Long term current carrying

A circuit that will be carrying a current continuously for long periods

without relay switching operation. (circuits for emergency lamps, alarm

devices and error inspection that, for example, revert only during

malfunction and output warnings with form B contacts) Continuous,

long-term current to the coil will facilitate deterioration of coil insulation

and characteristics due to heating of the coil itself.

For circuits such as these, please use a magnetic-hold type latching

relay. If you need to use a single stable relay, use a sealed type relay

that is not easily a󰀨ected by ambient conditions and make a failsafe

circuit design that considers the possibility of contact failure or

disconnection.

DC Coil operating power

Steady state DC current should be applied to the coil. The wave form

should be rectangular. If it includes ripple, the ripple factor should be

less than 5%.

However, please check with the actual circuit since the electrical

characteristics may vary. The rated coil voltage should be applied to

the coil and the set/reset pulse time of latching type relay di󰀨ers for

each relays, please refer to the relay's individual specications.

Coil connection

When connecting coils of polarized relays, please check coil polarity

(+,-) at the internal connection diagram (Schematic). If any wrong

connection is made, it may cause unexpected malfunction, like

abnormal heat, re and so on, and circuit do not work. Avoid

impressing voltages to the set coil and reset coil at the same time.

Usage, Transport, and Storage Conditions

During usage, storage, or transportation, avoid locations

subjected to direct sunlight and maintain normal temperature,

humidity and pressure conditions.

Temperature/Humidity/Pressure

When transporting or storing relays while they are tube

packaged, there are cases the temperature may di󰀨er from the

allowable range. In this case be sure to check the individual

specications. Also allowable humidity level is inuenced by

temperature, please check charts shown below and use relays

within mentioned conditions. (Allowable temperature values

di󰀨er for each relays, please refer to the relay's individual

specications.)

Maximum allowable voltage and temperature rise

Proper usage requires that the rated coil voltage be impressed on the

coil. Note, however, that if a voltage greater than or equal to the

maximum continuous voltage is impressed on the coil, the coil may

burn or its layers short due to the temperature rise. Furthermore, do

not exceed the usable ambient temperature range listed in the catalog.

Operate voltage change due to coil temperature rise

(Hot start)

In DC relays, after continuous passage of current in the coil, if the

current is turned OFF, then immediately turned ON again, due to the

temperature rise in the coil, the pick-up voltage will become somewhat

higher. Also, it will be the same as using it in a higher temperature

atmosphere. The resistance/temperature relationship for copper wire

is about 0.4% for 1°C, and with this ratio the coil resistance increases.

That is, in order to operate of the relay, it is necessary that the voltage

be higher than the pick-up voltage and the pick-up voltage rises in

accordance with the increase in the resistance value. However, for

some polarized relays, this rate of change is considerably smaller.

Precautions for Coil Input

Ambient Environment

For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.

https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp

1) Temperature:

The tolerance temperature range differs for each relays,

please refer to the relay’s individual specifications

2) Humidity:

5 to 85 % RH

3) Pressure:

86 to 106 kPa

Dew condensation

Condensation occurs when the ambient temperature drops

suddenly from a high temperature and humidity, or the relay is

suddenly transferred from a low ambient temperature to a high

temperature and humidity. Condensation causes the failures like

insulation deterioration, wire disconnection and rust etc.

Panasonic Corporation does not guarantee the failures caused

by condensation.

The heat conduction by the equipment may accelerate the

cooling of device itself, and the condensation may occur.

Please conduct product evaluations in the worst condition of

the actual usage. (Special attention should be paid when high

temperature heating parts are close to the device. Also please

consider the condensation may occur inside of the device.)

Icing

Condensation or other moisture may freeze on relays when the

temperature become lower than 0°C.This icing causes the sticking of

movable portion, the operation delay and the contact conduction failure

etc. Panasonic Corporation does not guarantee the failures caused by

the icing.

The heat conduction by the equipment may accelerate the cooling of

relay itself and the icing may occur. Please conduct product

evaluations in the worst condition of the actual usage.

Low temperature and low humidity

The plastic becomes brittle if the switch is exposed to a low

temperature, low humidity environment for long periods of time.

High temperature and high humidity

Storage for extended periods of time (including transportation periods)

at high temperature or high humidity levels or in atmospheres with

organic gases or sulde gases may cause a sulde lm or oxide lm to

form on the surfaces of the contacts and/or it may interfere with the

functions. Check out the atmosphere in which the units are to be

stored and transported.

GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE

Package

In terms of the packing format used, make every e󰀨ort to keep the

e󰀨ects of moisture, organic gases and sulde gases to the absolute

minimum.

Silicon

When a source of silicone substances (silicone rubber, silicone oil,

silicone coating materials and silicone lling materials etc.) is used

around the relay, the silicone gas (low molecular siloxane etc.) may be

produced.

This silicone gas may penetrate into the inside of the relay. When the

relay is kept and used in this condition, silicone compound may adhere

to the relay contacts which may cause the contact failure. Do not use

any sources of silicone gas around the relay (Including plastic seal

types).

Others

Cleaning

1) Although the environmentally sealed type relay (plastic sealed type,

etc.) can be cleaned, avoid immersing the relay into cold liquid (such

as cleaning solvent) immediately after soldering. Doing so may

NOx Generation

When relay is used in an atmosphere high in humidity to switch a load

which easily produces an arc, the NOx created by the arc and the

water absorbed from outside the relay combine to produce nitric acid.

This corrodes the internal metal parts and adversely a󰀨ects operation.

Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use

at high humidity is unavoidable, please contact our sales

representative.
