The Omron E2K-C20MC1 2M Proximity Sensor uses an unshielded capacitive sensing configuration with a 20 mm sensing distance. It provides a DC 3-wire NPN output with NO operation through a pre-wired 2 m cable and operates from 12 to 24 VDC. Response frequency is 40 Hz, current consumption is 13 mA max. at 24 VDC, and differential travel is specified at 15% max. of sensing distance. A yellow operation indicator is provided, together with reverse-polarity protection and a surge suppressor. The sensor is specified for operation and storage from -25 to 70°C with humidity from 35% to 95%.
Temperature influence for the E2K-C20MC1 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%. IP65 is the listed protection level. For another E2K capacitive sensor retaining DC 3-wire NPN NO operation and a pre-wired 2 m cable but extending the sensing distance to 25 mm, see E2K-C25ME1 2M.
