Precautions

Do not ignore the following items that are essential for securing

safety during Sensor operation.

�

Do not use the Sensor in locations with explosive or flam-

mable gas.

�

Do not use the Sensor in the water or electrically conductive
solutions.

�

Do not disassemble, repair, or modify the product.

�

Make sure that the power supply specifications, such as AC

or DC, are correct.

�

Do not apply voltage or current exceeding the rated ranges.

�

Do not make mistakes in wiring, such as mistakes in polarity.

�

Be sure to connect the load correctly.

�

Do not short-circuit the load terminals.

DESIGNING

Load Relay Contact

If E3G is connected to an inductive load with contacts that spark
when the load is turned OFF (e.g., a contactor or valve), the

normally-closed side may be turned ON before the normally-open

side is turned OFF or vice-versa. If both normally-open output

and normally-closed output are used simultaneously, apply an

surge suppressor to the load.

Stabilization on Power-up

The Sensor needs 100 ms to be ready to operate after it is turned

ON. The devices connected to E3G wait until the Sensor is ready

to operate. If the Sensor and load are connected to separate

power supplies, be sure to turn ON the Sensor first.

Power OFF

A single pulse signal may be output from the Sensor immediately

after it is turned OFF. This will occur more frequently if a timer or

counter is connected to the Sensor and power is supplied to the

timer or counter independently. Be sure to supply power to the

timer or counter from the built-in power supply of the Sensor.

Power Supply

If a standard switching regulator is used, be sure to ground the

FG (frame ground) and G (ground) terminals, otherwise the

Sensor may malfunction due to the switching noise of the

regulator.

Repeated Cable Bending

Do not bend the sensor cable repeatedly.

High-tension Lines

Do not wire power lines or high-tension lines alongside the lines

of the Sensor in the same conduit, otherwise the Sensor may be

damaged or may malfunction due to induction. Be sure to wire

the lines of the Sensor separated from power lines or

high-tension lines or laid in an exclusive, shielded conduit.

WIRING

The E3G has a built-in function to protect the Sensor from load

short-circuiting. If load short-circuiting results, the output will be

turned OFF. In that case, check the wiring and turn ON the E3G

again so that the short-circuit protection circuit will be reset. This

function will operate if the output current flow is at least 2.0 times

the rated load current. If an inductive load is connected to the
E3G, make sure that the inrush current does not exceed 1.2

times the rated load current.

The cable can be extended up to a total length of 100 m, on

condition that the thickness of the wire is at least 0.3 mm.

MOUNTING

Mounting Conditions

If Sensors are mounted face-to-face, make sure that no optical
axes cross each other. Otherwise, mutual interference may

result.

Be sure to install the Sensor carefully so that the directional

angle range of the Sensor will not be directly exposed to
intensive light, such as sunlight, fluorescent light, or incandescent

light.

Do not strike the Photoelectric Sensor with a hammer or any
other tool during the installation of the Sensor, or the Sensor will

loose its water-resistive properties.

Use M4 screws to mount the Sensor.

When mounting the case, make sure that the tightening torque

applied to each screw does not exceed 1.2 N S m.

M12 Connector

Be sure to connect or disconnect the M12 connector after turning

OFF the Sensor.

Be sure to hold the connector cover when connecting or

disconnecting the M12 connector.

The M12 connector must be only hand-tightened.

If the M12 connector is not connected securely, the proper

degree of protection of the Sensor may not be maintained or the

connector may be disconnected due to vibration.

Water Resistance

Do not use the product in water, in rain, or outdoors.

Tighten the operation cover screws and terminal block cover

screws to a torque of 0.3 to 0.5 N S m in order to ensure water

resistivity.

MAINTENANCE AND INSPECTION

Cleaning

Use only water and mild detergent. Do not use harsh chemicals

or solvents.

OPERATING ENVIRONMENT

Do not install the E3G in locations with the following conditions.

�

Excessive dust.

�

Corrosive gases.

�

Directly exposed to sprays of water, oil, or chemicals.

�

Directly exposed to vibration or shock.
