Omron E2A-M12KS04-M3-C2 Proximity Sensor
Omron E2A-M12KS04-M3-C2 combines shielded inductive sensing with an M12 cylindrical short body, 4 mm sensing distance, and 0 to 3.2 mm setting range. The sensor uses DC 3-wire NPN NC switching through a 4-pin M8 connector and operates from 12 to 24 VDC. Response frequency is 1,000 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow operation indicator and reverse-polarity, surge, and short-circuit protection are specified.

The Omron E2A-M12KS04-M3-C2 Proximity Sensor combines an M12 cylindrical shielded inductive body with a 4 mm sensing distance, 0 to 3.2 mm setting range, and short-body construction. It uses DC 3-wire NPN NC switching through a 4-pin M8 connector and operates from 12 to 24 VDC. Response frequency is 1,000 Hz. Control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow operation indicator is provided, while output reverse-polarity, supply reverse-polarity, surge suppression, and short-circuit protection are specified. This configuration supports Omron M12 NPN proximity sensor applications requiring shielded mounting and normally closed output logic.
Operating conditions for the E2A-M12KS04-M3-C2 extend from -40 to 70°C, with storage from -40 to 85°C. IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2 are specified. Brass-nickel-plated or stainless-steel housing options and PBT components are included in the construction information. Shielded sensing supports installation close to surrounding metal, while the short M12 body reduces mounting depth. The M8 connector also allows detachable wiring. For a compact E2A alternative with an M8 body, 2 mm sensing distance, PNP NO output, and 3-pin M8 connector, see E2A-S08LS02-M5-B1.
