If the tightening is insufficient, the degree of protection will not be maintained and the Sensor may become loose due to vibration. The appropriate tightening torque is 0.3 to 0.4N· m . When using another, commercially available connector, follow the usage and tightening torque instructions provided by the manufacturer.

Load

Do not use a load that exceeds the rated load.

Low-temperature Environments

Do not touch the metal surface with your bare hands when the temperature is low. Touching the surface may result in a cold burn.

Oily Environments

Do not use the Sensor in oily environments. They may damage parts and reduce the degree of protection.

Modifications

Do not attempt to disassemble, repair, or modify the Sensor.

Outdoor Use

Do not use the Sensor in locations subject to direct sunlight.

Cleaning

Do not use thinner, alcohol, or other organic solvents.

Otherwise, the optical properties and degree of protection may be degraded.

Cleaning

Do not use highly concentrated cleaning agents. Otherwise, malfunction may result. Also, do not use high-pressure water with a level of pressure that exceeds the stipulated level. Otherwise, the degree of protection may be reduced.

Surface Temperature

Burn injury may occur. The Sensor surface temperature rises depending on application conditions, such as the ambient temperature and the power supply voltage. Use caution when operating or performing maintenance on the Sensor.

Cable Bending

Do not bend the cable in temperatures of -25^ or below. Otherwise, the cable may be damaged.

Precautions for Correct Use

Do not use the Sensor in any atmosphere or environment that exceeds the ratings.

Do not install the Sensor in the following locations.

(1)Locations subject to direct sunlight
(2)Locations subject to condensation due to high humidity
(3)Locations subject to corrosive gas
(4)Locations where the Sensor may receive direct vibration or shock

Connecting and Mounting

(1) The maximum power supply voltage is 30 VDC. Before turning the power ON, make sure that the power supply voltage does not exceed the maximum voltage.
(2)Laying Sensor wiring in the same conduit or duct as high-voltage wires or power lines may result in malfunction or damage due to induction. As a general rule, wire the Sensor in a separate conduit or use shielded cable.
(3) Use an extension cable with a minimum thickness of 0.3 ~mm^2 and less than 50 ~m long.
(4)Do not pull on the cable with excessive force.
(5)Pounding the Photoelectric Sensor with a hammer or other tool during mounting will impair water resistance. Also, use M3 screws.
(6)Mount the Sensor either using the bracket (sold separately) or on a flat surface.
(7)Be sure to turn OFF the power supply before inserting or removing the connector.

Power Supply

If a commercial switching regulator is used, ground the FG (frame ground) terminal.

Power Supply Reset Time

The Sensor will be able to detect objects 100 ms after the power supply is tuned ON. Start using the Sensor 100 ms or more after turning ON the power supply. If the load and the Sensor are connected to separate power supplies, be sure to turn ON the Sensor first.

Turning OFF the Power Supply

Output pulses may be generated even when the power supply is OFF.

Therefore, it is recommended to first turn OFF the power supply for the load or the load line.

Load Short-circuit Protection

This Sensor is equipped with load short-circuit protection, but be sure to not short circuit the load. Be sure to not use an output current flow that exceeds the rated current. If a load short circuit occurs, the output will turn OFF, so check the wiring before turning ON the power supply again. The short-circuit protection circuit will be reset. The load shortcircuit protection will operate when the current flow reaches 1.8 times the rated load current. When using a capacitive load, use an inrush current of 1.8 times the rated load current or lower.

Water Resistance

Do not use the Sensor in water, rainfall, or outdoors.

When disposing of the Sensor, treat it as industrial waste.

Detection of Glossy Objects

Mount the Sensor at an angle of 5^ to 15^ , as shown in the following diagram. This will improve the mark detection capability.

Operating Procedure

Two-point Teaching Using Teaching Button

1. Place the point for which you want the output to go ON in the beam spot position. Then, press and hold the teaching button for at least 2 seconds.

The teaching indicator (red) will begin flashing quickly. (This indicates that the output ON teaching operation should begin.) Perform the following operation within 7 seconds of when you start pushing the button. (After 7 seconds, the Unit will return to its initial condition.)

1. Press the teaching button for approximately 0.5 second. The teaching indicator (red) will light for approximately 0.5 second to show that the output ON teaching is completed.

The teaching indicator (red) will then begin flashing quickly again to show that the output OFF teaching operation should begin.

1. Place the point where you want the output to go OFF in the beam spot position.

1. Press the teaching button for approximately 0.5 second. The teaching indicator (red) will light for approximately 0.5 second to show that the output OFF teaching is completed.

OFF point	Lit Off	Off Off

Automatic teaching (Remote)

1. Send a pulse with a duration of at least 2 s but less than 10 s min. to the remote control input (pink).
2. Teaching will be performed automatically when the mark (the light level with the shorter detection time) passes through the beam spot.

Make sure the mark passes through the beam spot for at least 1.5 ms.

Pass the mark through the beam spot at least seven times to complete the teaching process.

There must be a difference in light intensity between the mark and the background for teaching to be successful.

1. Detection will begin and the output will turn ON when the mark (the light level with the shorter detection time) is detected.

Note: Determine when teaching has been completed by confirming that the output turns ON for the mark and OFF for the background. If the output does not turn ON for the mark and OFF for the background within one minute after the remote control input is applied, teaching has not been successful. Apply the remote control input again.

*If seven marks do not pass within one minute of the remote control input, the teaching operation will be cancelled.

Precautions for Using Automatic Teaching (Remote)

• With automatic teaching (remote), the output is always turned ON for the light level with the shorter detection time. Use 2-point teaching (manual) to turn OFF the output for the light level with the shorter detection time.
• Faulty detection is possible when using automatic teaching (remote) if there is considerable movement in the sensing object or if the surface of the object is stepped or contains protrusions.

In cases such as these, use 2-point teaching.

• Do not use automatic teaching for backgrounds that are not monochrome.
