Mounting and dismounting
Mounting Step 1
2. 5 to 2. 9 mm dia 20. 1 to 20. 2 mm
Insert the snap holder into the mounting hole from the front
Verify the correct position (a clicking sound can be heard)
Insert the sensor into the snap holder from the back
Verify the correct position (a clicking sound can be heard)
Apply soft pressure to the sensor lens in the indicated areas (e. g. with two thumbs)
Remove the sensor
Press down both snap-fits and push the snap holder forward.
Remove the snap holder

[. . . ] Caution
Do not use the product with voltage in excess of the rated voltage. Otherwise, explostion may result.
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 mm2 and less than 100 m long. (5) Pounding the Photoelectric Sensor with a hammer or other tool during mounting will impair water resistance. (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.
When cleaning the product, do not apply a high-pressure spray of water to one part of the product. Otherwise, parts may become damaged and the degree of protection may be degraded. High-temperature environments may result in burn injury.
Precautions for Safe Use
The following precautions must be observed to ensure safe operation of the Sensor.
Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved.
Do not use the Sensor in an environment where explosive or flammable gas is present.
If a commercial switching regulator is used, ground the FG (frame ground) terminal.
Be sure to hold the connector cover when inserting or removing the connector. Be sure to tighten the connector lock by hand; do not use pliers or other tools. 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. 39 to 0. 49 N·m for M12 connectors.
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.
Do not use a load that exceeds the rated load.
Rotation Torque for Sensitivity Adjustment
Adjust with a torque of 0. 05 N·m or less.
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 load short-circuit 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 higher.
Environements with Cleaners and Disinfectants (e. g. , Food Processing Lines)
Do not use the Sensor in environments subject to cleaners and disifectants. [. . . ] CHANGE IN SPECIFICATIONS Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the product may be changed without any notice. When in doubt, special model numbers may be assigned to fix or establish key specifications for your application on your request. [. . . ]
