Omron E2A-M12KN08-M1-B3 Proximity Sensor
Omron E2A-M12KN08-M1-B3 is a cylindrical M12 unshielded inductive proximity sensor with an 8 mm sensing distance, 0 to 6.4 mm setting distance, and short-body design. 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 800 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. The sensor includes output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection. The E2A-M12KN08-M1-B3 is grouped with dual-output proximity sensors from Omron sensing technology.

The Omron E2A-M12KN08-M1-B3 Proximity Sensor combines an M12 cylindrical unshielded inductive sensing body with an 8 mm sensing distance, 0 to 6.4 mm setting distance, and short-body structure. It uses 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 800 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 provided. Output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection are specified for the sensor circuit.
Operating conditions for the E2A-M12KN08-M1-B3 cover -40 to 70°C, with storage from -40 to 85°C. Environmental ratings include IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2. The short M12 housing reduces installation depth, while the unshielded format provides the specified 8 mm sensing range. Its combined NO and NC output gives control designers two switching states within this model configuration. Brass-nickel-plated or stainless-steel housing options and PBT are listed among the construction details. For another M12 E2A sensor with an 8 mm sensing distance and PNP output, see E2A-M12KN08-M1-B2.
