Product Overview
The Omron E2E-C03N02-WC-B1 2M is a 3 mm cylindrical inductive proximity sensor from the E2E small-diameter series, manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
The sensor detects ferrous metal at 2 mm when unshielded (non-flush mounted). Output is 3-wire PNP normally open, switching up to 50 mA at 10 to 30 VDC. Response frequency is 3.5 kHz, which is high enough for small-part counting or high-speed spindle tool detection.
The 2 m PVC cable is oil-resistant. The body is stainless steel (SUS303) with a heat-resistant ABS sensing face, IP67 rated. Overall length is 33 mm and weight is approximately 30 g. For the NPN normally open version, pick the E2E-C03N02-WC-C1 2M. For the 0.8 mm shielded variant on the same 3 mm body, pick the E2E-C03SR8-WC-B1 2M. For an M8 threaded body at the same 2 mm range, pick the E2E-X2D1-M1.
Key Features
- E2E small-diameter 3 mm cylindrical inductive proximity sensor, unshielded, 2 mm range
- 3-wire PNP normally open output, 10 to 30 VDC, 50 mA switching, 3.5 kHz response
- 2 m oil-resistant PVC cable, stainless steel SUS303 body, IP67, 33 mm overall length
- 10 mA max current, -25 to +70 degC operating, 1.5 mm max pre-travel
- SKU: E2E-C03N02-WC-B1 2M
- Series: Omron E2E-series small-diameter inductive proximity sensor
- Voltage: 10 TO 30 VDC
Best-Fit Applications
- Tool seating verification on a CNC spindle where the 3 mm body fits in the spindle clearance and the 3.5 kHz response handles high-RPM detection
- Small-part counting on a packaging line where micro-gears or fasteners drop through a narrow chute and the 3 mm diameter clears the geometry
- Spare drop-in for an existing E2E cell where the previous sensor failed and the field wiring is PNP 3-wire
Buying Checklist
- Pick the E2E-C03N02-WC-B1 2M for a 3 mm inductive sensor with PNP NO output and a 2 m cable.
- Pick the E2E-C03SR8-WC-B1 2M instead when the cabinet needs flush mounting and the 0.8 mm shielded range is enough.
- Pick the E2E-X2D1-M1 instead when an M8 threaded body is needed at 2 mm range and the wiring is a connector instead of a cable.

FAQ for E2E-C03N02-WC-B1 2M
Can the E2E-C03N02-WC-B1 2M be flush mounted?
No. The 2 mm range on this unit is the unshielded (non-flush) rating. Flush mounting will reduce the usable range. If the panel needs flush mounting, pick the shielded E2E-C03SR8-WC-B1 2M at 0.8 mm range.
What wire colours does the E2E-C03N02-WC-B1 2M use?
Brown is +V, blue is 0 V and black is the PNP output. Wire brown to the 24 VDC supply, blue to common, and black to the PLC input terminal.
Can the cable be replaced if it gets cut?
The cable is moulded into the body and is not user-replaceable. If the cable gets damaged in service, replace the whole sensor. The 5 m cable version (E2E-C03N02-WC-B1 5M) is available for longer runs.
Does the E2E-C03N02-WC-B1 2M need a special amplifier?
No. It is a self-contained 3-wire DC sensor with a built-in amplifier. Wire it directly to a 24 VDC PLC input card or a sensor terminal block such as the G7TC-ID16 DC24V.
