8 mm unshielded, NPN NC, M12
The Omron E2EL-X8ME2-M1 is an unshielded threaded-barrel proximity sensor with an 8 mm sensing distance, NPN normally closed output, and an M12 4-pin connector. The NC output means the sensor switches off when a target is present — a common choice for fail-safe interlocks where loss of signal should indicate a detected object.
M12 connector and NC wiring
The M12 4-pin connector mates directly with standard M12 cordsets used on most PLC input modules and fieldbus blocks. Because the output is NPN (sinking), the load connects between the positive supply and the output — confirm the PLC input type is sinking-compatible before wiring.
