Engineering suggestions require suitability checks for your installation.
The through-beam sensing design supports contact-free detection in compact machinery.
Align the emitter and receiver across a 500 mm gap and confirm reliable interruption with the actual object.
The built-in amplifier and 1 ms response support discrete presence sensing in automated equipment.
Use a compatible 12 to 24 VDC input and follow Omron mounting and optical-axis alignment guidance.
