Peratech rolls out touchscreen industrial controller

Peratech has developed a touchscreen industrial controller that uses the company's standard keyboard sensor featuring Opaque QTC (quantum tunnelling composite) force-sensing technology. According to the company, the sensor accurately measures both the amount of pressure applied to the keypad and its precise location, at a better resolution than today's capacitive touchscreen technology.

As an integral part of a total human machine interface (HMI) solution, QTC technology promises to offer many advantages over capacitive and other existing touch solutions, greater safety, greater accuracy, better consistency and higher reliability, in a cost effective solution with low EMI, power and size constraints, Peratech noted.

Operational at temperatures lower than -20C and higher than 60C, the QTC technology can work behind a variety of surfaces including glass, metal or plastic, and it uses less processing power compared to projected-capacitive solutions. The overall power budget is also less with a QTC-based solution as it only requires power when touched, unlike capacitive that always has its sensing field powered up and thus draining the battery life, claimed Peratech.
