Product Overview
The Omron E2K-C25ME1 2M is a cylindrical capacitive proximity sensor designed for targets an inductive sensor cannot see - plastic pellets, glass, cardboard, wood, and liquids through non-metallic container walls. 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 unshielded M30 barrel delivers a 25 mm maximum sensing range, adjustable down to 3 mm via the 18-turn sensitivity potentiometer on the rear of the head. The 3-wire DC NPN normally-open output switches up to 200 mA into a PLC digital input, and the red operation LED on the cap shows the target state from across the cabinet.
Mount away from grounded metal behind the target face, and confirm the IP64 rating is sufficient for the wash-down zone - the E2K-C25 family is IP64 only, not IP67.
Key Features
- 70 Hz response frequency (~14 ms)
- M30 unshielded barrel, 34 mm body diameter
- DC 10-40 V supply (12-24 V nominal)
- Adjustable 3-25 mm sensing range (18-turn pot on rear)
- SKU: E2K-C25ME1 2M
- Series: E2K-C25 cylindrical capacitive proximity sensor
- Voltage: 10-40 V
Best-Fit Applications
- Detecting liquid level through a non-metallic sight glass on a process tank
- Hopper level presence check on a plastic-resin silo
- Counting cardboard cartons on a packaging line conveyor
Buying Checklist
- Choose E2K-C25ME2 if the load needs to be powered when no target is present (NC, fail-safe).
- Choose E2K-C25MY1 / MY2 when the cabinet runs on AC 100-220 V and lacks a 24 VDC sensor rail.
- Verify the sensor's IP64 housing suits the wash-down area; for IP67 rating, the E2K-F flat line is sealed higher.

FAQ for E2K-C25ME1 2M
What is the difference between E2K-C25ME1 and E2K-C25ME2?
E2K-C25ME1 is NPN normally-open - the output transistor closes when a target enters the sensing range. E2K-C25ME2 is NPN normally-closed - the output is closed when no target is present and opens on target. Use ME1 when the PLC expects a 'target present' input; use ME2 when the wiring is fail-safe and a missing target should trigger the alarm.
Can this sensor detect water or oil through a glass container?
Yes. Capacitive sensors detect the dielectric difference between air and the target, so a water or oil level inside a glass or plastic sight glass is a normal use. The sensitivity pot should be set just past the maximum target distance, and the glass wall should be no thicker than 5 mm for stable detection.
Is the E2K-C25ME1 2M IP67 rated?
No. The E2K-C25 family is IP64 rated - protected against splashing water but not rated for full immersion or high-pressure wash-down. For an IP67 capacitive sensor on a wash-down line, the E2K-F flat-body family (IP67) or a remote-head capacitive sensor like the E2KQ-X is the right pick.
