The CM30-25NPP-EC1 is a 30 mm cylindrical capacitive sensor from the Series CM family, rated for a 25 mm sensing distance on a non-flush mount. That 25 mm is the maximum detection range against a grounded metal target in the standard IEC 60947-5-2 test condition; for non-metallic media (liquids, powders, glass) the effective range drops to roughly 40–60% of that figure, so a 25 mm nominal means you design for about 10–15 mm of reliable detection on a plastic bottle or a grain level. The non-flush mounting requirement means the sensing face must protrude past any surrounding metal — embed it in a steel bracket and the field couples to the bracket, not the target. The PNP output switches 200 mA at 10–36 VDC, which is the standard sink for a PLC digital input or a relay coil in a 24 VDC control loop. At 50 Hz switching frequency it is a presence sensor, not a high-speed part — adequate for a conveyor jam or a tank-level gate, but not for counting parts on a fast pick-and-place. The IP68 and IP69K ratings mean the sensor body and the M12 connector withstand both continuous immersion (IP68, 1 m depth) and high-pressure, high-temperature washdown (IP69K, 80 °C water at 80–100 bar). That is the spec that decides fit for food-and-beverage, dairy, or pharmaceutical lines where a CIP (clean-in-place) cycle would destroy an IP67 sensor.
Deployment context
The M12 4-pin connector mates to a standard M12 cordset (A-coded, 4-pin, typically 0.34 mm² conductors) — no special breakout cable needed. The 30 mm barrel threads into a standard 30 mm hole or a bracket clamp; the non-flush rule means the sensing face must be the forward-most metal surface. In a washdown zone the IP69K rating holds provided the mating connector is also rated to IP69K and the cable gland is tightened to the manufacturer's torque spec. The 10–36 VDC supply range covers 24 VDC nominal with headroom for brownout conditions down to 10 V.
