Engineering suggestions require suitability checks for your installation.
Detect small opaque parts as they pass through a compact mechanism.
Position the object through the 5 mm slot and verify alignment, target opacity and switching timing.
Read a moving flag or interrupter in a machine mechanism or assembly fixture.
Choose the L-shaped body form for mounting access and connect the NPN output to a compatible input.
