Omron E2A-M18KN16-M1-B2 Proximity Sensor
Omron E2A-M18KN16-M1-B2 is a cylindrical M18 unshielded inductive proximity sensor with a 16 mm sensing distance, 0 to 12.8 mm setting distance, and short-body construction. It uses 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 400 Hz, while control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. Electrical protection includes output reverse polarity, power-source reverse polarity, surge suppression, and short-circuit protection. The E2A-M18KN16-M1-B2 belongs to M18 long-range proximity sensors from Omron industrial sensing products for automation equipment.

The Omron E2A-M18KN16-M1-B2 Proximity Sensor uses a cylindrical M18 unshielded inductive sensing body with a 16 mm sensing distance, 0 to 12.8 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 400 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, together with output reverse-polarity protection, power-source reverse-polarity protection, surge suppression, and short-circuit protection.
Operating conditions for the E2A-M18KN16-M1-B2 extend from -40 to 70°C, while storage covers -40 to 85°C. Environmental protection includes IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2. The short M18 body helps reduce mounting depth, while the unshielded sensing arrangement provides the stated 16 mm detection range. The M12 connector permits detachable wiring during replacement or service. Brass-nickel-plated or stainless-steel housing options and PBT components are listed for this sensor family. For another M18 E2A model with an 8 mm sensing distance and PNP NO switching, see E2A-M18LS08-M1-B1.
