The Omron E2B-M18KS05-M1-C1 is a shielded inductive prox from the E2B series — M18 threaded barrel, 5 mm sensing distance, NPN normally open output, with an M12 connector for fast field wiring. Lifecycle is current, so Omron is still making them — no need to chase last-time-buy leftovers.
Shielded construction means you can flush-mount this sensor into metal without false triggers. The short-body barrel gives you a bit more room in tight turret or conveyor-rail pockets.
