Omron E2A-M12KS04-M1-C1 Proximity Sensor
Omron E2A-M12KS04-M1-C1 is a cylindrical M12 shielded inductive proximity sensor with a 4 mm sensing distance, 0 to 3.2 mm setting distance, and short-body construction. It uses a DC 3-wire NPN output with NO operation through a 4-pin M12 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 LED and protection against reverse polarity, surge, and short circuits are specified. The E2A-M12KS04-M1-C1 is listed among M12 shielded NPN proximity sensors from Omron industrial sensors.

The Omron E2A-M12KS04-M1-C1 Proximity Sensor uses a cylindrical M12 shielded inductive sensing body with a 4 mm sensing distance, a 0 to 3.2 mm setting distance, and short-body construction. It provides a DC 3-wire NPN output with NO operation through a 4-pin M12 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 LED is provided, while output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection are specified for the electrical circuit.
Operating conditions for the E2A-M12KS04-M1-C1 extend from -40 to 70°C, while storage covers -40 to 85°C. IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2 are specified. The shielded M12 configuration combines a 4 mm sensing range with NPN NO switching and a compact short-body design. Its M12 connector supports detachable field wiring during replacement or maintenance. Brass-nickel-plated or stainless-steel housing options and PBT are listed among the construction materials. The short body helps reduce required rear installation depth in machine structures. For a compact E2A M8 sensor with 2 mm sensing distance and PNP NC output, see E2A-S08KS02-WP-B2 2M.
