Omron E2A-M12KS04-M1-B3 Proximity Sensor
Omron E2A-M12KS04-M1-B3 is an M12 shielded inductive proximity sensor with a 4 mm sensing distance, a 0 to 3.2 mm setting distance, and short-body construction. It uses a DC 3-wire PNP output with combined NO and NC switching through an 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. Output reverse-polarity, power-source reverse-polarity, surge, and short-circuit protection are specified. The E2A-M12KS04-M1-B3 is included among dual-output proximity sensors from Omron industrial sensing solutions.

The Omron E2A-M12KS04-M1-B3 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 PNP output with both NO and NC switching through an 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 is specified together with output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection for the electrical circuit.
Operating conditions for the E2A-M12KS04-M1-B3 cover -40 to 70°C, while storage extends from -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 construction supports mounting close to surrounding metal, while the short-body format reduces required installation depth. Dual PNP NO and NC switching provides both output states from the stated configuration. Brass-nickel-plated or stainless-steel housing options and PBT are listed among the construction materials. The M12 connector supports detachable field wiring during installation and servicing.
