50 mm capacitive sensor

January 2004 Sensors & Transducers

SIE Sensorik in Viernheim, Germany, presents a new capacitive disk sensor. As a distance sensor with an adjustable sensing distance of up to 25 mm, the compact disk sensor, 50 mm in diameter and only 10 mm high, is suitable for scanning plastics, glass, ceramics, wood, etc.

The sensor's large active surface also enables it to be used as a filling level indicator, since it can detect liquids and granules through plastic or glass walls. Typical applications here would include medical equipment, or use as an overfill safety feature in whirlpools. Two holes in the housing, plus a variable cable outlet, provide several options for attaching the plastic housing.

The sensor is protected to IP67. The control state is indicated by an LED visible from three sides, with rotary switches provided for user configuration of the starting position as NO/NC and PNP/NPN. (Attractive quantity discounts provide a favourable price/performance ratio for bulk buyers.)
