Omron E2A-M12KN08-M1-B2 Proximity Sensor
Omron E2A-M12KN08-M1-B2 is an M12 unshielded inductive proximity sensor with an 8 mm sensing distance, 0 to 6.4 mm setting distance, and short-body construction. It provides a DC 3-wire PNP output with NC operation through a 4-pin M12 connector and operates from 12 to 24 VDC. Response frequency is 800 Hz, and control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. Protection functions include output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection. The E2A-M12KN08-M1-B2 is part of M12 proximity sensors from Omron industrial automation for machine sensing applications.

The Omron E2A-M12KN08-M1-B2 Proximity Sensor uses an M12 cylindrical unshielded inductive sensing body with an 8 mm sensing distance, 0 to 6.4 mm setting distance, and short-body construction. It provides a DC 3-wire PNP output with NC operation through a 4-pin 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 indicator is specified. Electrical protection includes output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection for industrial control wiring.
Operating conditions for the E2A-M12KN08-M1-B2 extend from -40 to 70°C, while storage covers -40 to 85°C. The sensor is specified with IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2. Its short M12 body helps reduce mounting depth, while the unshielded sensing arrangement provides the stated 8 mm range. The M12 connector also enables detachable cabling during sensor replacement. Brass-nickel-plated or stainless-steel housing options and PBT are listed among the construction details. For an E2A model with the same M12 size and 8 mm sensing range using NPN switching, see E2A-M12KN08-M1-C2.
