The Omron E2E-X12B2L18-M1TJ 0.3M is a shielded M18 inductive proximity sensor from the E2E NEXT series, rated IP69K and IP67G for washdown zones, with a PNP NC output and 12 mm sensing range on a 0.3 m M12 Smartclick pigtail. Shielded construction means it mounts flush in metal without sensing-range derating—handy when there's a bracket or a standoff in the way. The NC output (normally-closed) is the fail-safe choice: if the sensor loses power or the target leaves, the signal breaks immediately.
What the ratings buy you in the field
Rated IP69K, IP67G, and IP67 for washdown and oil resistance. Body is nickel-plated brass with a PBT sensing face. The 0.3 m M12 pigtail with Smartclick connector means you can pull the sensor without cutting wires—but you'll need a matching M12 female cordset. At 0.3 m, that's a panel wire or a short jumper, not a long run. Supply is 10 to 30 VDC, standard for 3-wire PNP. The 12 mm sensing distance is the standard 3× factor for shielded M18; no surprises on gap.
How it compares to the E2E-X12B3DL18 5M
Both are M18 shielded PNP sensors with the same 12 mm sensing range and IP69K rating. The B3D variant adds IO-Link (COM2) and has a 5 m fixed PVC cable with NO+NC outputs instead of the NC-only output on this part.
