Padless touch sensor

The padless touch sensor (PTS) is a solid-state touch control technology that uses signal generation and detection to provide an alternative to other switch technologies such as membrane switches, mechanical keyboards and solid-state keyboards.

Appliance controls, industrial process controls, automotive, kiosks, point-of-sale terminals and medical equipment are among the many applications where the PTS technology can be applied.

Any dielectric material including glass, plastic, polycarbonate, marble and wood can be used for touch surfaces. Custom graphics can be printed directly onto these touch surfaces and key size can be designed to any customer requirements. Options include backlight, lighted keys, tactile response or simulated potentiometer. The response time, once the PTS is touched, is less than 4 milliseconds per key. The device operates in temperatures ranging from -20 up to +105°C.
