Capacitive keypads

Our capacitive keypads are suitable for a wide range of applications. Capacitive switching technology is becoming increasingly popular in both industrial and household applications. At Printec-DS, we specialize in the following options:

  • Capacitive switches behind glass or plastic as a system solution
  • ITO films or nanowire technology
  • Controller incl. software as a complete solution possible
  • Mechanical integration in customized designs
  • Combination with mechanical keys
  • Homogeneous symbol backlighting

 

Solutions from Printec-DS

Our system solutions with capacitive individual switches are based on a sensor solution directly on the PCB. One or more capacitive switches are applied directly to a printed circuit board. This robust design now makes it possible to build a touch system with any front panels on it. This enables both homogeneously backlit solutions in LED technology with customer-specific colors as well as solutions with any number of switches and displays as an integration solution in customer-specific designs. This means that our product range of mechanical switches (which always require openings through closed surfaces) is optimally complemented by this protected sensor technology, as combination solutions of both technologies are also possible.

 

Since our capacitive switch is based on permanent capacity measurement and evaluation, it can also be used as a proximity sensor and can be programmed with any function. For example, LED illuminations when approaching are possible as well as a differentiated actuation upon contact. This is made possible by sensitivity settings in the software and the possibility of the sensor to still sense through different materials - for example through 4mm thick plastic, through 6mm glass or through work gloves frequently used in industrial applications. Due to the system design behind a protective front panel, our system is extremely wear-resistant, scratch-proof, dust-proof and resistant to common cleaners, oil, moisture and liquids (protection class IP65 and higher possible). Our sensor technology can also be very useful in areas where high temperature resistance is required or where hygiene, disinfection and frequent cleaning play a major role.

This robust design allows applications in outdoor and indoor areas that are not irritated by water drops, moisture or ice deposits. In particular, our capacitive pushbutton can be used for industrial applications. These can be in the control area of ​​machine tools or coffee machines as well as in the area of ​​actuation for locking systems and gates in the outdoor and indoor area. By using individual front panels, applications with special surfaces such as integrated Braille are possible.

We develop complete systems with touch operating elements for you according to your requirements and ideas. Based on all our touch technologies, we take responsibility for the overall system, the technical implementation as a 3D model and the integration into specified installation spaces as a complete development service. We advise you on all technical issues from the initial idea to the realization of the first prototypes through to series production. From design and assembly to complete system testing and acceptance, we can provide everything from a single source.
