Omron E2KQ-X10ME1 Capacitive Sensor, NPN-NO, 6-10mm, IP66

The E2KQ-X10ME1 is an Omron capacitive proximity sensor built for detecting non-metallic materials — plastics, liquids, glass, wood. Output is NPN normally open, 3-wire, so it sinks current to ground when a target enters the sensing field, a standard interface for PLC sinking inputs. Sensing distance is adjustable across 6 mm to 10 mm, though the actual reach depends on the target material's dielectric constant. Unshielded construction means the field projects forward without a flush-mount shield; plan for side clearance around the sensing face. Supply voltage runs 10 to 30 VDC. The built-in LED lights when the output is active, useful for panel walk-throughs. Rated IP66, so it handles washdown spray and dust. Response frequency is 35 Hz — adequate for moderate-speed detection (bottles on a conveyor, level in a plastic tank) but not for high-rate part counting.
