Omron E2E-S04N02-WC-B2 5M Small-diameter Proximity Sensor
Omron E2E-S04N02-WC-B2 5M features an M4 unshielded sensing body with 2 mm sensing and DC 3-wire PNP NC switching. A pre-wired 5 m PVC cable provides fixed connection, while the setting range covers 0 to 1.4 mm. It operates from 10 to 30 VDC with a 3.5 kHz response frequency. The E2E-S04N02-WC-B2 5M sits within the E2E Small-diameter Series, while other NC wiring formats can be explored through the M4 proximity sensor range supplied through Omron Industrial Sensors.

The Omron E2E-S04N02-WC-B2 5M Small-diameter Proximity Sensor uses an M4 unshielded sensing body with a 2 mm sensing distance and a setting range from 0 to 1.4 mm. Its DC 3-wire PNP output operates as normally closed through a pre-wired 5 m PVC cable, providing additional wiring reach while retaining a compact sensor body. The sensor operates from 10 to 30 VDC with a 3.5 kHz response frequency. Ferrous metal is specified using an iron 6 × 6 × 1 mm standard object. Control output is rated at 50 mA max. with a 2 V max. voltage drop. Output reverse polarity, power supply reverse polarity, surge, and load short-circuit protection are included. The M4 threaded design is suited to installations where available mounting space is restricted.
For applications specifying an Omron M4 proximity sensor with unshielded 2 mm sensing, PNP NC switching, and extended fixed cable wiring, the applicable model is the E2E-S04N02-WC-B2. Operation and storage temperatures cover -25 to 70°C, with IEC 60529 IP67 and an oil-resistant in-house specification. Its layout also addresses Omron PNP proximity sensor, Omron 2 mm proximity sensor, Omron small diameter proximity sensor, and Omron pre-wired proximity sensor requirements. The longer 5 m cable changes installation reach without altering the sensing distance or output logic. For the same M4 unshielded PNP NC arrangement with a shorter 2 m cable, see E2E-S04N02-WC-B2 2M.
