How to use

Install the PM-K65-P so that the sensing axis aligns with the target area to be monitored. Connect the device to a suitable 5–24 V DC power source and wire the switching output to the control input of the receiving device or PLC according to the installation guidelines. Select the required switching mode (light ON or dark ON) to match the detection logic of the system. Adjust mounting and alignment to ensure reliable detection and avoid interference from ambient light sources where possible.

Recommendations

For consistent operation, mount the sensor on a stable surface and protect it from direct exposure to intense light sources that could cause false triggers. Verify compatibility with the control circuit’s voltage and input type before wiring. Periodically check alignment and clean the optical window to maintain detection reliability in dusty or oily environments.
