Padless touch sensor

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

Appliance controls, industrial process controls, automotive, kiosks, point-of-sale terminals and medical equipment are among the applications where the sensors can be used. The open architecture design allows for each integration into existing control switch applications.

Any dielectric material including glass, plastic, polycarbonate, marble, and wood can be used for touch surfaces. Custom graphics can be printed directly onto these surfaces and key size can be designed to any user requirements.

Options include backlight, lighted keys, tactile response or simulated potentiometer. The response time, once the PTS is touched, is less than 4 ms per key. The device operates in temperatures ranging from -20 up to +105°C.
