Omron E2E-S05N03-MC-C2 Small-diameter Proximity Sensor
Omron E2E-S05N03-MC-C2 uses an M5 unshielded sensing body with 3 mm sensing and a 0 to 2.1 mm setting range. Its DC 3-wire NPN output operates as normally closed through an M8 3-pin connector. The sensor works from 10 to 30 VDC with a 2 kHz response frequency. The E2E-S05N03-MC-C2 is included in the E2E Small-diameter Series, while related connector versions can be found in the 3 mm NPN proximity sensor range offered by Omron Industrial Sensor Products.

The Omron E2E-S05N03-MC-C2 Small-diameter Proximity Sensor uses an M5 unshielded body with a 3 mm sensing distance and a setting range from 0 to 2.1 mm. Its DC 3-wire NPN circuit provides normally closed output through an M8 3-pin connector, allowing detachable wiring without a permanently attached cable. Operating voltage is 10 to 30 VDC with a 2 kHz response frequency. Ferrous metal is specified using an iron 9 × 9 × 1 mm standard object. Control output is rated at 100 mA max. with a 2 V max. voltage drop. Output reverse polarity protection, power supply reverse polarity protection, surge suppression, and load short-circuit protection are included. The compact M5 structure provides a threaded mounting option where available sensor space is limited.
For an Omron NPN proximity sensor requiring compact M5 mounting, unshielded 3 mm sensing, NC switching, and detachable M8 wiring, the specified model is the E2E-S05N03-MC-C2. Operation and storage extend from -25 to 70°C, with IEC 60529 IP67 and an oil-resistant in-house specification. Its format also matches Omron small diameter proximity sensor, Omron 3 mm proximity sensor, Omron unshielded proximity sensor, and Omron M8 connector proximity sensor requirements. The connector arrangement can simplify replacement compared with fixed-cable versions using the same sensing format. For the same M5 unshielded NPN NC arrangement using a pre-wired 2 m cable, see E2E-S05N03-WC-C2 2M.
