The flat housing of this newest capacitive sensor offers numerous mounting options, while maintaining room for visibility of 2 LEDs as well as push-button teach-in functionality.

As a result of its thin design, the CQ28 offers numerous mounting options, including clamp fitting, tie-wrap mounting, and recessed installation. It features two LEDs, which show the current switching state and the quality of detection. The CQ28 allows for optimal adjustment of the sensing distance through its push-button teach-in functionality. Finally, the availability of both a PNP and NPN switching output versions provides flexibility within the same product.

The CQ28 has an enhanced EMC, which reliably prevents spurious switching caused, for example, by interfering surge voltages. These surges can come from electrostatically charged granulate in bulk material silos, mobile telephones, radio devices or magnetic valves, and contacts or frequency converters. The IP 68 housing ensures dependable function under almost all operating conditions.

With the CQ28, liquids and bulk materials can be reliably detected through non-metallic walls in sensing distances of up to 10 mm. For example, a typical application for the CQ28 is fill level detection in tanks, containers or pipe systems detecting all types of media (e.g. liquids, solids, powders).
