Capacitive Touch Sensors: capaTEC® Sensor Technology for Reliable Detection
Wherever robust and reliable operation is required despite the operating surface being contaminated by dust, water, steam, oils and greases, as well as acids, EBE capacitive touch sensors are at home. The effects of coatings on the operating surface are compensated for by means of a multidimensional measurement of touches, for example by a human finger.Überall wo es auf robuste und zuverlässige Betätigung trotz Verschmutzung der Bedienoberfläche durch Staub, Wasser, Dampf, Öle und Fette sowie Säuren ankommt, sind die kapazitiven Touch Sensoren von EBE zuhause. Die Einflüsse von Belägen auf der Bedienoberfläche werden aufgrund einer multidimensionalen Vermessung von Berührungen, beispielsweise durch einen menschlichen Finger, kompensiert.
Individual customization options allow for maximum performance and dynamics for safe and reliable control panels. Based on proven algorithms, the capacitive touch sensors are adapted to a wide range of material thicknesses of the non-conductive control surface, such as real glass, acrylic, wood or plastic, and a maximum dynamic range is achieved. The capacitive touch sensors or sliders can be realized on the same circuit board and supplied and calculated by a µcontroller.
Depending on the requirements, the electrodes are designed to be planar or concave or convex using a flex circuit board. Any interfaces can be individually generated and realized. The arrangement of the respective touch sensors and switches can be freely selected. Several capacitive touch sensors or sliders can be centrally controlled via a µcontroller. It is also possible to easily adapt a control panel to an existing infrastructure and interface world. This eliminates the need for expensive redesigns of existing machine interfaces and interfaces of central electronic boards. The size and shape of the touch sensors are individually adapted to existing conditions. In addition, EBE develops and supplies an individual housing for the sensor electronics if required.
The development of capacitive touch sensors or touch sensors is based on the application-specific requirements of our customers. The sensors are developed in a targeted and customized manner. The capaTEC® sensor technology developed by EBE is the basis for this.
