Operation
Sensitivity adjustment The light source switch and reflective plate can be moved horizontally and vertically to set them in the center of the illumination area of the red incident light indicator lamp, allowing the operator to check whether the green stability indicator lamp is illuminated.

Precautions
Correct Use
Design Fuzzy mutual interference prevention · If the light source switches for the reflective plates are arranged in a row, light from a neighboring light source switch may be received, causing erroneous light reception signals and errors. · The fuzzy reciprocal interference prevention function monitors interference light for a certain period of time before illumination, and gathers data on the strength of the interference light and the frequency of incidence. It then determines the risk of error due to these two factors using fuzzy logic and controls the timing of illumination to reduce the risk. (When risk is low) · Light is emitted after interfering light is gone.
Interference light
Installation Sensor installation · When installing a photoelectric switch, avoid tapping with a hammer. This may damage the water resistance function. · Use an M4 screw, tightened to a torque of no more than 1. 18 Nm. (When using the mounting bracket) · To set the sensor on the mechanical axis, use the optical axis locking holes. · When it is not possible to mount on the mechanical shift, move the photoelectric switch vertically or horizontally so that it is located in the center of the area illuminated by the incident light indicator lamp.

M4 hole
For adjustment Light axis adjustment Adjust the optical axis of the clamp to the direction of detection object approach. The optical axis of the photoelectric switch is the same as the mounting axis of the clamp, enabling easy adjustment. Optical axis locking hole By fitting screws into the optical axis locking holes, the mounting bracket is set onto the mounting shaft of the mounting bracket.
