Omron E2A-M18KN16-M1-C2 Proximity Sensor
Omron E2A-M18KN16-M1-C2 is an M18 cylindrical unshielded inductive sensor providing a 16 mm sensing distance, 0 to 12.8 mm setting range, and short-body construction. It uses DC 3-wire NPN NC output 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 operation LED and reverse-polarity, surge, and short-circuit protection are specified. The E2A-M18KN16-M1-C2 belongs to the M18 proximity sensor range available across Omron Sensor Products.

The Omron E2A-M18KN16-M1-C2 Proximity Sensor uses an M18 cylindrical unshielded inductive body with a 16 mm sensing distance, 0 to 12.8 mm setting range, and short-body construction. It provides DC 3-wire NPN 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 operation indicator is provided along with output reverse-polarity, supply reverse-polarity, surge, and short-circuit protection. The extended detection range makes this model suitable for Omron M18 proximity sensor applications requiring NPN normally closed operation.
Operating conditions for the E2A-M18KN16-M1-C2 extend from -40 to 70°C, while storage covers -40 to 85°C. IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-3 are specified. Brass-nickel-plated or stainless-steel housing options and PBT components are listed. The unshielded M18 arrangement supports the stated 16 mm sensing range, while the short body reduces rear mounting depth. Its M12 connector allows detachable field wiring. For a larger M30 model with a 15 mm sensing distance and NPN NC output, see E2A-M30KS15-M1-C2.
