The Omron E2E-X4C212 2M is a shielded M12 inductive proximity sensor from the E2E NEXT series. It gives you a 4 mm sensing range, DC 3-wire NPN output, and normally closed operation. The 2-meter PVC cable is pre-wired, and the body is standard length. No IO-Link here — straight three-wire NPN, which matches a lot of legacy PLC inputs and simple presence detection.
The E2E-X4C212 2M is specifically normally closed. Many M12 shielded proximity sensors in this class are normally open — if your circuit expects a break on target, this one is the right pull. No IO-Link means it's a drop-in for basic 3-wire NPN inputs without configuring a master.
