Omron E2A-M30KN20-M1-B3 Proximity Sensor
Omron E2A-M30KN20-M1-B3 has an M30 unshielded cylindrical sensing body with a 20 mm inductive sensing distance and 0 to 16 mm setting range. The short-body sensor uses DC 3-wire PNP output with NO+NC switching and an M12 connector. It works from 12 to 24 VDC and has a 100 Hz response frequency. Control output is specified at 200 mA max. at 32 VDC max., with voltage drop limited to 2 V. A yellow LED indicates operation, while reverse-polarity, surge, and short-circuit safeguards are included.

The Omron E2A-M30KN20-M1-B3 Proximity Sensor has an M30 cylindrical unshielded sensing face with a 20 mm inductive sensing distance and a 0 to 16 mm setting range. Its short housing uses DC 3-wire PNP output with NO+NC switching through an M12 connector. Operating voltage is 12 to 24 VDC, while response frequency is specified at 100 Hz. The control output handles 200 mA max. at 32 VDC max. with a maximum voltage drop of 2 V. A yellow LED shows operating status. Reverse-polarity safeguards are provided for the output and supply circuits, together with surge suppression and short-circuit protection. The NO+NC output distinguishes this model from single-state PNP versions.
Temperature ratings for the E2A-M30KN20-M1-B3 extend from -40 to 70°C during operation and -40 to 85°C during storage. The enclosure is specified to IP67 under IEC 60529 and IP69K under DIN 40050, with EMC according to EN60947-5-2. Housing construction includes brass-nickel-plated or stainless-steel options and PBT components. Its M30 unshielded sensing design supports 20 mm detection in a short-body format. For an M30 E2A model with a longer 30 mm sensing distance and NPN NO+NC switching, see E2A-M30LN30-M1-C3.
