Omron E2B-M12KN05-M1-C1 Proximity Sensor
Omron E2B-M12KN05-M1-C1 is a cylindrical M12 unshielded inductive proximity sensor with a 5 mm sensing distance, 0 to 4 mm setting distance, and short-body construction. It provides a DC 3-wire NPN output with NO operation through an M12 connector and operates from 10 to 30 VDC. Ferrous metal is the specified detectable object, with a 15 × 15 × 1 mm standard sensing object. Response frequency is 800 Hz, while control output is rated 200 mA max. at 30 VDC max. with a 2 V max. voltage drop. The E2B-M12KN05-M1-C1 is included among M12 NPN proximity sensors from Omron industrial automation products.

The Omron E2B-M12KN05-M1-C1 Proximity Sensor uses a cylindrical M12 unshielded inductive sensing body with a 5 mm sensing distance, a 0 to 4 mm setting distance, and short-body construction. It provides a DC 3-wire NPN output with NO operation through an M12 connector and operates from 10 to 30 VDC. Ferrous metal is the specified detectable object, with a 15 × 15 × 1 mm standard sensing object. Response frequency is 800 Hz, while control output is rated 200 mA max. at 30 VDC max. with a 2 V max. voltage drop. A yellow operation indicator and protection against reverse polarity, surge conditions, and short circuits are specified.
Operating and storage conditions for the E2B-M12KN05-M1-C1 cover -25 to 70°C. IP67 according to IEC 60529 and EMC according to EN60947-5-2 are specified. Nickel-plated brass, PBT, zinc-plated iron, and PVC are included among the listed construction materials. The short M12 housing helps reduce installation depth, while the unshielded sensing arrangement provides the stated 5 mm range for ferrous-metal detection. NPN NO switching is combined with detachable M12 connectivity for service access. For another E2B sensor using NPN switching but a larger M18 body, 8 mm sensing distance, and pre-wired 2 m cable, see E2B-M18LS08-WP-C2 2M.
