Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Long-range conveyor passage detection
A conveyor line may need object detection across a wide or obstructed installation span.
Potential use
The through-beam emitter and receiver provide a 20 m rated path; align both units and verify target opacity and clearance.

PNP
0.5 ms
2. Machine access or part presence sensing
A machine may need a binary signal when an opaque part breaks a fixed optical path.
Potential use
Selectable Light-ON/Dark-ON PNP output supports compatible control logic after choosing the wiring mode and confirming installation safeguards.
