Omron E2A-M18KN16-M1-B3 Proximity Sensor
Omron E2A-M18KN16-M1-B3 is an M18 unshielded inductive proximity sensor with a 16 mm sensing distance, 0 to 12.8 mm setting distance, and short-body design. 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 400 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow LED indicates operation, and reverse-polarity, surge, and short-circuit protection are specified. The E2A-M18KN16-M1-B3 is included among 16 mm inductive proximity sensors from Omron factory automation sensing products.

The Omron E2A-M18KN16-M1-B3 Proximity Sensor combines an M18 cylindrical unshielded inductive body with a 16 mm sensing distance, 0 to 12.8 mm setting distance, and short-body design. 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 400 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow LED provides operation indication, and output reverse-polarity, power-source reverse-polarity, surge, and short-circuit protection are specified.
Operating conditions for the E2A-M18KN16-M1-B3 cover -40 to 70°C, while storage extends from -40 to 85°C. The sensor is rated IP67 according to IEC 60529 and IP69K according to DIN 40050, with EMC specified to EN60947-5-3. The unshielded sensing face provides the stated 16 mm range, while the short body reduces rear installation depth. Dual NO and NC outputs provide two switching states in one configuration. Brass-nickel-plated or stainless-steel housing options and PBT components are listed for this E2A construction. For an M30 E2A model with 20 mm sensing distance and similar dual PNP switching, see E2A-M30KN20-M1-B3.
