Tastaturcontroller

Standard controller with capacitive sensor foil

This controller could be used to evaluate any customized capacitive sensor foils.
It is able to evaluate 16 buttons or a 4 channel slider and 12 buttons. Adaptation for wheel and slider possible.

The controller is fully compatible to the Arduino® Shields and it has an USB-interface with HID Protocol. Additionally there are 16 TTL outputs,
one for each button.

We offer two standard sensor foils in addition which have 16 touch buttons and could be cut from 1 to 16 buttons in a pattern. One foil is for high sensitivity and the other for design application with background lighting.

Description:

benefits:

  • operation possible by gently touching without pressure
    e.g. by pressing on glass
  • no moving parts therefore no mechanical wear
  • closed front, easy to clean
  • resistant to chemicals, contamination, vandalism

possible applications:

  • as a replacement for mechanical buttons/ switches
  • in hygienically demanding environments
    (e.g. medicine, foot industry, ...)
  • in vandalism endangerd areas
