Omron E2E-S04N02-WC-B1 2M Small-diameter Proximity Sensor
Omron E2E-S04N02-WC-B1 2M provides 2 mm sensing through an M4 unshielded body with a 0 to 1.4 mm setting range. Its DC 3-wire PNP output operates as normally open through a pre-wired 2 m PVC cable. Supply voltage is 10 to 30 VDC and response frequency reaches 3.5 kHz. The E2E-S04N02-WC-B1 2M forms part of the E2E Small-diameter Series, with similar fixed-cable choices covered in the 2 mm PNP proximity sensor range offered among Omron Sensor Products.

The Omron E2E-S04N02-WC-B1 2M Small-diameter Proximity Sensor provides a 2 mm sensing distance through an M4 unshielded body with a setting range from 0 to 1.4 mm. DC 3-wire PNP normally open output is supplied through a pre-wired 2 m PVC cable, allowing direct fixed wiring without a detachable connector. The operating supply is 10 to 30 VDC and response frequency is rated at 3.5 kHz. Ferrous metal is referenced using an iron 6 × 6 × 1 mm standard object. Control output is rated at 50 mA max. with a 2 V max. voltage drop. Reverse polarity protection for the output and supply, surge suppression, and load short-circuit protection are included. The compact M4 threaded structure supports installations where sensor diameter must remain small.
Where an Omron small diameter proximity sensor needs M4 mounting, unshielded 2 mm sensing, PNP NO switching, and fixed cable wiring, the specified version is the E2E-S04N02-WC-B1. Operation and storage temperatures extend from -25 to 70°C, together with IEC 60529 IP67 and an oil-resistant in-house rating. This configuration also fits Omron PNP proximity sensor, Omron 2 mm proximity sensor, and Omron pre-wired proximity sensor requirements. Its 2 m lead offers a practical cable length where extended 5 m wiring is unnecessary. For the same M4 unshielded 2 mm PNP NO sensor using an M8 pre-wired connector, see E2E-S04N02-CJ-B1 0.3M.
