Omron E2NC-EA21 2M Proximity Sensor
Omron E2NC-EA21 2M is an amplifier unit with an NPN output configuration, two outputs plus one input, and selectable NO/NC operation. It uses a pre-wired 2 m cable and operates from a 10 to 30 VDC power supply. Ferrous metal is the specified detectable object. The unit provides a 24 VDC listed current value and a 30 VDC max. output rating, with power-supply reverse-polarity, output short-circuit, and output reverse-polarity protection. Its display section includes green and white 7-segment displays with orange and blue status indicators. The E2NC-EA21 2M is included under smart proximity sensor products from Omron industrial sensing.

The Omron E2NC-EA21 2M Proximity Sensor Amplifier Unit provides an NPN output configuration with two outputs plus one input and selectable NO/NC operation. It uses a pre-wired 2 m cable and operates from a 10 to 30 VDC supply. Ferrous metal is the specified detectable object. The listed current value is 24 VDC, while the output rating is 30 VDC max. The display section uses 7-segment indicators with a green sub display and white main display, and the display direction can be switched between normal and reversed. Orange OUT and NO/NC indicators, a blue ST indicator, and an orange output-selection indicator are also listed. Protection includes power-supply reverse polarity, output short-circuit, and output reverse polarity.
Operating conditions for the E2NC-EA21 are -25 to 40°C, with storage from -30 to 70°C and humidity from 35% to 85%. Polycarbonate and PVC are listed as construction materials. The amplifier unit uses the pre-wired 2 m connection rather than a sensor-head connector, while NO/NC selection is handled within the stated NPN output arrangement. No sensing distance is listed for this amplifier unit itself. The display direction can be switched between normal and reversed, and the dual-output model includes a dedicated output-selection indicator. For another E2NC product using a connector-based cylindrical sensing head with a 1 mm sensing distance, see E2NC-ED01.
