Introduction

The most often used control device is probably simple pushbutton. Computer keyboard contain a lot of such buttons. Computer mouse, TV remote control, PDA, phone, electronic tools, toys, homes and cars are full of buttons. This is simple device, but -thanks to mechanic parts- also common source of problems. Limited lifetime often limits lifetime of the whole apparatus.

Moreover, electronic systems with mechanical buttons often have to contain special circuits, that improve noisy input signal. Or there has to be spent processor resources to make this input signals applicable. And in addition, the machanical construction is too complicated.

But there is a solution: Capacitive Touch Sensors. With this proximity touch sensors, all the problems are solved. Touch sensors has no mechanical part, output signal is clear and the construction is very simple. The apparatus lifetime is much prolonged, button is fully integrated and there is a lot of additional functions.

The capacitive touch sensor prinicple is not new, but what is quite new, is the technology background. To become a word leader in the field of touch sensors, it requires a years of development and testing. But as a result we offer excellently reliable sensors, clear to designer and simple to user.

Compared to other competitor's products, the TS devices senses frequency change caused by near conductive object -the finger for example. The strong point is in time division multiple frequency principle, automatic differential mode compensation, enhanced temperature and humidity compensation and great noise elimination.

TS sensors have an exellent noise immunity, wide temperature and humidity range, low number of external components, compact design and a lot of additional functions.
