Omron E2K-C25ME1 2M Proximity Sensor
Omron E2K-C25ME1 2M provides unshielded capacitive detection with a 25 mm sensing distance and a DC 3-wire NPN output with NO operation. It uses a pre-wired 2 m cable and operates from 12 to 24 VDC. Differential travel is specified at 15% max. of sensing distance when adjusted to 25 mm ±10% with the standard sensing object. Response frequency is 70 Hz, while current consumption is 10 mA max. at 12 VDC and 16 mA max. at 24 VDC. A red detection indicator, reverse-polarity protection, surge suppression, and IP66 protection are specified. The E2K-C25ME1 is listed under capacitive proximity sensors from Omron industrial sensors.

The Omron E2K-C25ME1 2M Proximity Sensor uses an unshielded capacitive sensing configuration with a 25 mm sensing distance. Its electrical arrangement is DC 3-wire NPN with NO operation, connected through a pre-wired 2 m cable and supplied from 12 to 24 VDC. Differential travel is specified at 15% max. of sensing distance when adjusted to 25 mm ±10% with the standard sensing object. Response frequency is 70 Hz. Current consumption is 10 mA max. at 12 VDC and 16 mA max. at 24 VDC. A red detection indicator is provided, together with reverse-polarity protection and a surge suppressor. These specifications distinguish the model by sensing range, transistor output, switching mode, and cable format.
Operating and storage temperature is -25 to 70°C without icing or condensation, with humidity from 35% to 95%. Temperature influence is ±15% max. of sensing distance at 23°C from -10 to 55°C and ±25% max. from -25 to 70°C. Insulation resistance is 50 MΩ min. at 500 VDC, dielectric strength is 1,000 VAC for 1 minute, and voltage influence is ±2% max. within rated voltage ±15%. IP66 is the specified degree of protection. For the corresponding 25 mm capacitive version that keeps DC 3-wire NO operation and a 2 m cable while changing from NPN to PNP output, see E2K-C25MF1 2M.
