Omron E2A-M18KN16-M1-B1 Proximity Sensor
Omron E2A-M18KN16-M1-B1 combines an M18 cylindrical unshielded body with a 16 mm inductive sensing distance and 0 to 12.8 mm setting range. Its short-body construction provides DC 3-wire PNP NO switching 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 LED indicates operation, and reverse-polarity, surge, and short-circuit protection are specified. The E2A-M18KN16-M1-B1 is part of the 16 mm proximity sensor range within Omron automation products.

The Omron E2A-M18KN16-M1-B1 Proximity Sensor uses an M18 cylindrical unshielded inductive body with a 16 mm sensing distance, 0 to 12.8 mm setting distance, and short-body construction. It provides DC 3-wire PNP output with NO operation through a 4-pin M12 connector and works from 12 to 24 VDC. Response frequency is 400 Hz. Control output is rated 200 mA max. at 32 VDC max. with a 2 V max. voltage drop. A yellow operation LED is provided together with output reverse-polarity, power-source reverse-polarity, surge, and short-circuit protection. Its extended range suits Omron M18 PNP proximity sensor applications requiring increased target clearance.
Operating conditions for the E2A-M18KN16-M1-B1 cover -40 to 70°C, while storage extends from -40 to 85°C. IP67 according to IEC 60529, IP69K according to DIN 40050, and EMC according to EN60947-5-2 are listed. Brass-nickel-plated or stainless-steel housing options and PBT components are specified. The unshielded M18 arrangement provides the stated 16 mm sensing distance, while short-body construction reduces rear installation depth. Its M12 connector enables detachable wiring during maintenance. This configuration also fits Omron M18 proximity sensors used for machine position and metal-part presence detection. For another M18 E2A model using shielded 8 mm sensing and dual PNP switching, see E2A-M18LS08-M1-B3.
