The Omron E2EX6B1T12M1OMS is a current-production inductive proximity sensor from the E2E series, rated for 6 mm sensing distance at 800 Hz switching frequency with a PNP normally-open output and M12 connector. It operates on 10–30 VDC, draws 16 mA, and pushes 100 mA load current — low enough for direct PLC inputs or small relay coils. The brass nickel-plated housing and IP67 rating suit it for washdown zones, coolant splash, or outdoor cabinet positions where moisture and vibration are routine.
The closest functional alternative is E2EX6B1T122MOMS — same sensing distance (6 mm), switching frequency (800 Hz), output type (PNP NO), voltage range, and current consumption. But the termination is the deciding factor: this version (E2EX6B1T12M1OMS) uses an M12 connector, while the sibling ships with a pre-wired cable. For a drop-in replacement into an existing cabinet, the pre-wired variant needs a wired connection; the M12 connector lets you swap the sensor head without touching the harness. Mounting style also differs — Through Hole here vs Quasi Flush Mount on the sibling — which may matter if panel preps were made for a flush barrel.
