Engineering suggestions require suitability checks for your installation.
1. Label or mark detection at a guide slot
A narrow feed path may need to detect a small mark or passing opaque part without aligning separate emitter and receiver axes.
Potential use
Position the grooved sensor around the material path and verify the 3 mm reference mark and mechanical clearance using the actual substrate.

2. Small-part passage confirmation
A station may need a switching signal as a small object passes through a fixed slot.
Potential use
Use the NPN output with a compatible controller input; validate the target and switching margin before production.
