1. Reflector-based part presence sensing
Check a part or carrier at a fixed sensing point using a reflector.
Select a compatible reflector and verify alignment, target size and sensor output polarity.
Omron E3Z-R61K 2M: retro-reflective with MSR sensor, up to 3 m, NPN, IP67.
The Omron E3Z-R61K 2M is a compact, built-in-amplifier retro-reflective with MSR photoelectric sensor. Its sensing distance is up to 3 m with the specified reflector and it provides a NPN output. The model uses a oil-resistant pre-wired 2 m, 12–24 V DC supply, 1 ms max response and IP67 protection.

Engineering suggestions require suitability checks for your installation.
Check a part or carrier at a fixed sensing point using a reflector.
Select a compatible reflector and verify alignment, target size and sensor output polarity.
Monitor product passage at a conveyor or packaging station.
Set Light-ON or Dark-ON mode and confirm response, wiring and optical conditions on the installed machine.
