Photoelectric Sensors Technical Guide

General Precautions

For precautions on individual products, refer to Safety Precautions in individual product information.

These Sensors cannot be used in safety devices for

presses or other safety devices used to protect

human life. These Sensors are designed for use in

applications for sensing workpieces and workers

that do not affect safety.

To ensure safety, always observe the following precautions.

● Wiring

● Operating Environment

(1) Do not use a Sensor in an environment where there are explosive or inflammable gases.

(2) Do not use the Sensor in environments where the cables may become immersed in oil or other liquids or where liquids may penetrate the

Sensor. Doing so may result in damage from burning and fire, particularly if the liquid is flammable.

WARNING

Precautions for Safe Use

Item Typical examples

Power Supply Voltage

Do not use a voltage in

excess of the operating

voltage range.

Applying a voltage in excess

of the operating voltage

range, or applying AC power

(100 VAC or greater) to a DC

Sensor may cause explosion

or burning.

---

Load Short-circuiting

Do not short-circuit the load.

Doing so may cause explo-

sion or burning.

Incorrect Wiring

Do not reverse the power

supply polarity or otherwise

wire incorrectly. Doing so

may cause explosion or

burning.

Connection without a

load

If the power supply is

connected directly without a

load, the internal elements

may burst or burn. Be sure to

insert a load when

connecting the power

supply.

Photoelectric Sensors Technical Guide

● Design

Power Reset Time

The Sensor will be ready to detect within approximately 100 ms after

the power is turned ON.

If the Sensor and the load are connected to separate power supplies,

turn ON the Sensor power before turning ON the load power. Any

exceptions to this rule are indicated in Safety Precautions in individual

product information.

Turning OFF Power

An output pulse may be generated when the power is turned OFF. It

is recommended that the load or load line power be turned OFF

before the Sensor power is turned OFF.

Power Supply Types

An unsmoothed full-wave or half-wave rectifying power supply cannot

be used.

Mutual Interference

Mutual interference is a state where an output is unstable because the Sensors are affected by light from the adjacent Sensors.

The following measures can be taken to avoid mutual interference.

Precautions for Correct Use

Counter-

measure Concept Through-beam Sensors Reflective Sensors

Use a Sensor

with the

interference

prevention

function.

If Sensors are mounted in close proximity, use Sensors with the interference prevention function.

10 or fewer Sensors: E3X-DA@-S, E3X-MDA, E3C-LDA Fiber Sensors

Performance, however, will depend on conditions. Refer to pages E3X-DA-S/E3X-MDA

and E3C-LDA.

5 or fewer Sensors: E3X-NA Fiber Sensors

2 or fewer Sensors: E3T, E3Z, E3ZM, E3ZM-C, E3S-C, E3G-L1/L3, or E3S-C Built-in Amplifier Photoelectric

Sensors (except Through-beam Sensors)

E3C Photoelectric Sensor with separate amplifier

Install an

inference

prevention

filter.

A mutual interference prevention polarizing filter can be

installed on only the E3Z-TA to allow close-proximity

mounting of up to 2 Sensors.

Mutual Interference Prevention Polarizing Filter: E39-E11

---

Separate

Sensors to

distance where

interference

does not occur.

Check the parallel movement distance range in the

catalog, verify the set distance between adjacent

Sensors, and install the Sensors accordingly at a

distance at least 1.5 times the parallel movement

distance range.

If the workpieces move from far to near, chattering may

occur in the vicinity of the operating point. For this type of

application, separate the Sensors by at least 1.5 times the

operating range.

Alternate

Emitters and

Receivers.

Close mounting of Sensors is possible by alternating

the Emitters with the Receivers in a zigzag fashion (up

to two Sensors). However, if the workpieces are close

to the Photoelectric Sensors, light from the adjacent

Emitter may be received and cause the Sensor to

change to the incident light state.

---

Offset the

optical axes.

If there is a possibility that light from another Sensor

may enter the Receiver, change the position of the

Emitter and Receiver, place a light barrier between the

Sensors, or take other measures to prevent the light

from entering the Receiver.

(Light may enter even if the Sensors are separated by

more than the sensing distance.)

If Sensors are mounted in opposite each other, slant the

Sensors as shown in the following diagram. (This is

because the Sensors may affect each other and cause

output chattering even if separated by more than the

Sensor sensing distance.)

6Adjust the

sensitivity.

Lowering the sensitivity will generally help.

Noise

Countermeasures for noise depend on the path of noise entry, frequency components, and wave heights. Typical measures are as given in the

following table.

● Wiring

Cable

Unless otherwise indicated, the maximum length of cable extension is

100 m using wire that is 0.3 mm2 or greater.

Exceptions are indicated in Safety Precautions in individual product

information.

Cable Tensile Strength

When wiring the cable, do not subject the cable to a tension greater than

that indicated in the following table.

Note: Do not subject a shielded cable or coaxial cable to tension.

Repeated Bending

Normally, the Sensor cable should not be bent repeatedly.

(For bending-resistant cable, see Attachment to Moving Parts on

page C-4.)

Separation from High Voltage (Wiring Method)

Do not lay the cables for the Sensor together with high-voltage lines

or power lines. Placing them in the same conduit or duct may cause

damage or malfunction due to induction interference. As a general

rule, wire the Sensor in a separate system, use an independent metal

conduit, or use shielded cable.

Work Required for Unconnected Leads

Unused leads for self-diagnosis outputs or other special functions

should be cut and wrapped with insulating tape to prevent contact with

other terminals.

Power Supply

When using a commercially available switching regulator, ground the

FG (frame ground) and G (ground) terminals.

If not grounded, switching noise in the power supply may cause

malfunction.

Example of Connection with S3D2 Sensor Controller

DC Three-wire NPN Output Sensors

Reverse operation is possible using the signal input switch on the

S3D2.

● Mounting

Attachment to Moving Parts

To mount the Photoelectric Sensor to a moving part, such as a robot

hand, consider using a Sensors that uses a bending-resistant cable

(robot cable).

Although the bending repetition tolerance of a standard cable is

approximately 13,000 times, robot cable has an excellent bending

tolerance of approximately 500,000 times.

Cable Bending Destruction Test (Tough Wire Breaking

Test)

With current flowing, bending is repeated to check the number of

bends until the current stops.

The testing conditions of the standard cable and robot cable are

different.

Refer to the values in the above table to check bend-resistant

performance under actual working conditions.

Securing Fibers

The E3X Fiber Unit uses a one-touch locking mechanism. Use the

following methods to attach and remove Fiber Units.

(1) Attaching Fibers

Open the protective cover, insert the fiber up to the insertion mark on

the side of the Fiber Unit, and then lower the lock lever.

(2) Removing Fibers

Open the protective cover, lift up the lock lever, and pull out the fibers.

● Adjustments

Optical Axis Adjustment

Move the Photoelectric Sensor both vertically and horizontally and set

it in the center of the range in which the operation indicator is lit or not

lit. For the E3S-C, the optical axis and the mechanical axis are the

same, so the optical axis can be easily adjusted by aligning the

mechanical axis.

Optical axis: The axis from the center of the lens to the center of

the beam for the Emitter and the axis from the

center of the lens to the center of the reception area

for the Receiver.

Mechanical axis: The axis perpendicular to the center of the lens.

Note:1.To maintain the fiber characteristics, make sure that the lock

is released before removing the fibers.

2. Lock and unlock the fibers at an ambient temperature of

−10 to 40°C.

● Operating Environment

Water Resistance

Do not use in water, in rain, or outside.

Ambient Conditions

Do not use this Sensor in the following locations. Otherwise, it may

malfunction or fail.

(1) Locations exposed to excessive dust and dirt

(2) Locations exposed to direct sunlight

(3) Locations with corrosive gas vapors

(4) Locations where organic solvents may splash onto the Sensor

(5) Locations subject to vibration or shock

(6) Locations where there is a possibility of direct contact with water,

oil, or chemicals

(7) Locations with high humidity and where condensation may result

Environmentally Resistive Sensors

The E32-T11F/T12F/T14F/T81F-S/D12F/D82F and E3HQ can be used

in locations (3) and (6) above.

Optical Fiber Photoelectric Sensors in Explosive Gas

Atmospheres

The Fiber Unit can be installed in the hazardous area, and the

Amplifier Unit can be installed in a non-hazardous area.

For explosion or fire due to electrical equipment to occur, both the

hazardous atmosphere and a source of ignition must be in the same

location. Optical energy does not act as an ignition source, thus there

is no danger of explosion or fire. The lens, case, and fiber covering are

made of plastic, so this setup cannot be used if there is a possibility of

contact with solvents that will corrode or degrade (e.g., cloud) the

plastic.

Electrical sparks or high-temperature parts that have sufficient energy

to cause explosion in a hazardous atmosphere are called ignition

sources.

Influence from External Electrical Fields

Do not bring a transceiver near the Photoelectric Sensor or its wiring,

because this may cause incorrect operation.

● Maintenance and Inspection

Points to Check When the Sensor Does Not Operate

•If the Sensor does not operate, check the following points.

(1) Are the wiring and connections correct?

(2) Are any of the mounting screws loose?

(3) Are the optical axis and sensitivity adjusted correctly?

(4) Do the sensing object and the workpiece speed satisfy the ratings

and specifications?

(5) Are any foreign objects, such as debris or dust, adhering to the

Emitter lens or Receiver lens?

(6) Is strong light, such as sunlight (e.g., reflected from a wall), shining

on the Receiver?

(7) Do not attempt to disassemble or repair the Sensor under any

circumstances.

(8) If you determine that the Sensor clearly has a failure, immediately

turn OFF the power supply.

Lens and Case

The lens and case of the Photoelectric Sensor are primarily made of

plastic. Dirt should be gently wiped off with a dry cloth. Do not use

thinner or other organic solvents.

•

The case of the E3ZM, E3ZM-C and E3S-C is metal. The lens,

however, is plastic.

● Accessories

Using a Reflector (E39-R3/R37/RS1/RS2/RS3)

During Application

(1) When using adhesive tape on the rear face, apply it after washing

away oil and dust with detergent. The Reflector cannot be

mounted if there is any oil or dirt remaining.

(2) Do not press on the E39-RS1/RS2/RS3 with metal or a

fingernail.This may weaken performance.

(3) This Sensor cannot be used in locations where oil or chemicals

may splash on the Sensor.

M8 and M12 Connectors

•Be sure to connect or disconnect the connector after turning OFF

the Sensor.

•Hold the connector cover to connect or disconnect the connector.

•Secure the connector cover by hand. Do not use pliers, otherwise

the connector may be damaged.

•If the connector is not connected securely, the connector may be

disconnected by vibration or the proper degree of protection of the

Sensor may not be maintained.

● Others

Values Given in Typical Examples

The data and values given as typical examples are not ratings and

performance and do not indicate specified performance. They are

rather values from samples taken from production lots, and are

provided for reference as guidelines. Typical examples include the

minimum sensing object, engineering data, step (height) detection

data, and selection list for specifications.

Cleaning
