How it compares to the PNP peer
The only functional difference between E2E-X5ME1- and E2E-X5MF1-M1 is the output transistor type: NPN vs PNP. Sensing distance (5 mm), shielding (unshielded), switching output (NO), connector (M12), and frequency (standard) are identical. Wiring mismatch means the sensor won't pull the input low on a sink-style card. No rewiring of the sensor side, but the load side must be reconfigured to match the input module's common.
