2 mm shielded inductive proximity sensor for ferrous targets
The Omron E2E-X2F1 is an M12 shielded inductive proximity sensor with a 2 mm nominal sensing distance on iron, ±10% tolerance. The standard sensing object is a 12 × 12 × 1 mm iron target. It operates on 12 to 24 VDC (10 to 30 VDC range including ripple) and draws 13 mA max. The PNP normally-open output switches at up to 1.5 kHz, which is fast enough for counting parts on a conveyor or detecting a cam lobe at moderate line speeds. The set distance is 0 to 1.6 mm, and differential travel is 10% max of sensing distance — meaning once the target is detected, the sensor releases it at about 1.8 mm away. This hysteresis prevents chatter near the switch point.
M12 barrel fit and panel integration
The M12 threaded barrel mounts through a 12 mm hole with two jam nuts. Shielded construction means the sensing face can be flush-mounted in metal without derating the sensing range — useful when the sensor sits in a tapped block or bracket. The standard sensing target is iron; correction factors apply for other metals (stainless ~0.7×, aluminum ~0.4×). For a stainless target, budget about 1.4 mm actual sensing distance.
