This Omron E2E-X18MB2L30-M1TJ 0.3M is an M30 unshielded inductive proximity sensor with a normally closed PNP output and 18 mm sensing distance. It carries IP67, IP67G, and IP69K ingress ratings, so it's built for washdown environments. It's a long body version—82.3 mm overall with 50 mm of thread—so you need the depth for mounting. The M12 pigtail with Smartclick connector gives you a durable connection that's easy to swap if it takes a hit.
Mounting and wiring notes
Because it's unshielded, leave clearance around the sensing face—check the 1x factor in the datasheet. The 0.3 m pigtail is short; plan for an extension if your cable run is longer. Wire it as a standard 3-wire DC sensor with 10–30 VDC supply. The M12 Smartclick connector locks tight and stays sealed.
