Fit and key ratings
Omron E2E-X1R5E2-N 2M is a shielded inductive proximity switch with a 1.5 mm sensing distance, NPN normally closed output, and a 2 m PVC cable — a common fit for flush-mounted position sensing in metal panels. The shielding means it can be mounted flush in steel without derating, which is standard for detecting small ferrous targets in tight spaces. Output is DC 3-wire, NPN collector load built-in, so it pulls the output low when the target is present.
Output logic and connection
The normally closed output is critical: the sensor is ON (output low) when the target is absent, and switches OFF when the target enters the sensing field. That logic is opposite of the normally open version, so a replacement must match the PLC or relay input circuit. The 2 m PVC cable is a fixed length — for longer runs you need a junction box or extension cable. If your panel is wired for an M12 connector, this part will not plug in directly; that is a different variant.
Comparison with E2E-X1R5E1-M1
The closest functional peer is E2E-X1R5E1-M1, which shares the same 1.5 mm shielded sensing distance and NPN output type, but differs in two ways: it is normally open (rather than NC) and terminates in an M12 connector rather than a 2 m cable. You cannot drop this NC cable version into a panel wired for an NO M12 sensor without rewiring the PLC input logic and changing the physical connection. If your BOM calls for NC and a cable, this is the correct SKU.
