Capacitive keys and keyboards
For special requirements in functionality and design
Capacitive keyboards – elegant and versatile input solutions
As specialists for high-quality input solutions, we also design and manufacture capacitive keyboards that are characterized by modern design and innovative technology.
Our offer includes capacitive units made of plastic, metal or glassthat can be seamlessly integrated into various housing designs. Our focus is on the development and production of capacitive keyboards with glass surfaces and acrylic.
Capacitive glass, especially tempered glass, offers an elegant, durable, and robust solution that meets the highest standards of design and functionality. Acrylic glass, on the other hand, represents a lightweight and cost-effective alternative that also impresses with a smooth and aesthetic surface.
The technology behind capacitive input systems
Capacitive input systems respond to the electrical conductivity of a person. Even a simple touch changes the electrical capacitance at the contact point. This change is precisely detected by sensors and then converted into an input signal. This technology enables smooth and intuitive operation – without the use of force.
In addition, capacitive keyboards not only offer precise input options such as wheels and sliders, but also set new standards in user interaction. These input systems impress with their versatility and at the same time open up new possibilities for modern designs.
Development and design
The development of capacitive input systems requires technical know-how and precise planning – but offers maximum design freedom with a compact designBy eliminating mechanical switches, capacitive input units enable a flat, modern, and reliable user interface – ideal for demanding HMI applications in industry, medical technology, or building technology.
We take over and accompany the entire development and construction Your capacitive input units – from the initial idea through the selection of suitable materials to the solution ready for series production.
Capacitive membrane keyboards
Our capacitive membrane keyboards represent innovative HMI solutions with maximum ease of use. Their flat design makes these keyboards the ideal choice for compact and modern device concepts – especially in medical technology, industrial automation, building management systems, as well as in device manufacturing and consumer electronics.
As a touch-sensitive keyboard, they enable precise and intuitive operation, without any mechanical pressure. The sealed surface is particularly hygienic and easy to clean. Thanks to their robust construction, our capacitive membrane keyboards offer high resistance to moisture, dust, dirt, and chemicals.
Protection classes up to IP67 can be easily implemented. Furthermore, they are extremely durable and wear-free, as there are no moving parts integrated – a real advantage for industrial applications with high demands on reliability and service life.
