Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Conveyor object detection
A line may need a non-contact signal when objects pass a defined station.
Potential use
Evaluate the 100 mm red-light sensing distance and selectable output on the actual object surface and background, using compatible PNP input logic.

2. Machine station presence check
A fixture may need to confirm that a component has reached a fixed working position.
Potential use
The sensor can provide a PNP switching signal after verifying target reflectivity, alignment and ambient-light conditions.
