The Omron E2A-M12LN08-M1-C1 is an M12-barrel inductive proximity sensor from the E2A series, a workhorse line for position detection on automated lines — conveyors, part-present sensing, cylinder position feedback. It carries an 8 mm nominal sensing distance on mild steel, which is the standard figure for an unshielded M12 sensor in this class — enough to detect a target before mechanical contact, but tight enough to reject objects outside the face cone.
No official replacement or cross-reference is documented for this order code. Source this exact part if the BOM calls for the E2A-M12LN08-M1-C1.
