Cautions For Use

Never use this product as a sensing device for personnel protection.
For sensing devices to be used as safety devices for press machines or for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
If this product is used as a sensing device for personnel protection, death or serious body injury could result.
For a product which meets safety standards, use the safety light curtain.

Use M4 screws with washers and M4 nuts. The tightening torque should be 0.5 N·m or less.
(Purchase the screws and nuts separately.)

Lighting / Blinking is selected by the operation mode switch on the emitter and the receiver.

The output operation mode is selected by the operation mode switch on the receiver.
(The switches must be set with the power supply off. The operation mode does not change if the switch setting is changed with the power supplied.)

Operation mode switch (Receiver)		Output operation	Operation indicator (Orange)
D-ON		ON in Dark state	Lights up when the output is ON
L-ON		OFF in Dark state	Lights up when the output is ON

Note:	LIGHT / BLINK switch is not related to the output operation selection.

Make sure that the power supply is off while wiring.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
Ensure that an isolation transformer is utilized for the DC power supply. If an autotransformer is utilized, the main body or power supply may be damaged.
If the used power supply generates a surge, connect a surge absorber to the power supply to absorb the surge.
In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint.

Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.
Although this sensor can detect slim objects by using the cross-beam scanning system, the size of the slim object which can be stably detected differs with the setting distance. Hence, when the sensor is used to detect slim objects, make sure to confirm stable detection using the actual objects.
In case of this sensor, light from the emitter spreads above and below the sensor. Hence, take care that if there is a reflective object above or below the sensor it will affect the sensing.
