Object detection with capacitive sensors

Non-contact detection of metallic, non-metallic, transparent, opaque, liquid and solid substances.

Capacitive sensors can detect all kinds of objects without any problems. The surface finish, color or shape of the object is irrelevant. The better the level of conductivity and grounding of an object is, the higher is the level of signal reserves and detection reliability. Many capacitive sensors can be flush mounted and are thus are suitable for protected, space-saving installation.

    Application tasks
    • Object detection/bulk goods

      The sensors for object detection and bulk goods feature an extremely wear-resistant housing. Especially in case of contact with granules, this minimizes wear and increases service life. Reliable detection of conductive or non-conductive objects does not depend on the material. The sensors can detect anything regardless of color, brightness or surface finish.  Sensing distances of up to 30 mm are possible for contactless detection.
