The Omron E2NC-EA21 2M is typically considered together with other sensors in the E2NC Smart Proximity Sensor family because they follow similar mounting patterns, supply ranges, and adjustment behaviour. In practice, engineers often review related models such as Omron E2S-Q13 1M (Compact Square Type, 1.6 mm sensing, Unshielded, DC 3-Wire NPN, NO, Pre-wired 1 M Cable), Omron E2K-X4MF1 2M (Capacitive, 4mm sensing, Unshielded, DC 3-wire, PNP, NO, Pre-wired 2 M Cable), and Omron E2KQ-X10ME1 2M (Capacitive, 10 mm sensing, Unshielded, DC 3-wire NPN, NO, Pre-wired 2 M Cable) when selecting the most suitable variant for a tank, chute, conveyor, or compact fixture location. Comparing type, usable sensing distance, mounting style, output configuration, switching mode, and connection method helps match each sensor to the available mechanical space and wiring layout. The E2NC-EA21 2M fits naturally into panels, machine frames, dosing systems, and process equipment where a robust Omron Smart Proximity Sensor is required for repeatable switching in industrial environments.
