Contactless control improves hygiene

The current situation with the coronavirus requires far-reaching measures to reduce the health risks for the people around us as much as possible.

Many customers currently have questions about the hygiene of operating units. Do the applications meet the necessary hygiene requirements?

Contactless CapKeys

Schurter has developed a special capacitive sensor with increased sensitivity thanks to active field line guidance. This achieves maximum sensitivity so that the finger is recognized as soon as it approaches. The field lines of the projected capacitive sensor surface are concentrated upwards instead of being scattered around the keypad. This enables contactless activation of the capacitive buttons. To activate a touch surface, all you need to do is bring your finger close to the capacitive field of the CapKeys.

Touchless PCAP touchscreen

By developing its own sensor design and fine-tuning the controller, Schurter has succeeded in making a projected capacitive touchscreen "touchless". The touchscreen reacts to a small distance between the finger and the actual surface. The hardware and software settings of the PCAP controller, particularly with regard to sensitivity, are decisive here.

The touchless operation of the CapKey and PCAP controls enables a higher standard of hygiene. Operating fronts no longer need to be touched for activation. This contactless actuation option in the application can be activated and deactivated by the customer.
