What It Is and What the Ratings Mean
Omron E2EQ-X3D1-M1GJ 0.3M is a shielded proximity switch with a 3 mm sensing distance, designed for flush mounting in metal. Output is a 2-wire DC normally open switching signal, and the connection uses an M12 pre-wired connector with a short 0.3 m cable. The M12 pinout follows the IEC 1-4 arrangement, so line up the connector orientation before fastening.
