... Light switches Industrial panels The QT110 / QT110H charge-transfer (“QT’”) sensor chips are self-contained digital ICs used to implement near-proximity or touch sensors. They project sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood. They can also turn small metal-bearing objects into intrinsic sensors, making them respond to proximity or touch ...

... SNS1 and SNS2 to make the piezo (if installed) sound a short tone for 75ms immediately after detection, to act as an audible confirmation. Option pins allow the selection or alteration of several other special features and sensitivity. Figure 1-2 2-wire operation, self-powered (not QT110H) 3.5 - 5.5V CMOS 1K Twisted 1N4148 ...

By implication it requires that the signal ground and the target object must both be coupled together in some manner for a capacitive sensor to operate properly. Note that there is no need to provide actual hardwired ground ...

... CMOS input, by doing nothing or at most adding a small non-critical capacitor from Out to ground (Figure 2-6). 2.2.6 O The QT110’s output is active low (QT110) or active high (QT110H) and can source 1mA or sink 5mA of non-inductive current. 5 Figure 2-3 Damping Piezo Clicks with R +2 ...

... Vcc, so that it lights when the sensor is active-low. If desired the LED can be connected from Out to ground, and driven on when the sensor is inactive, but only with less drive current (1mA). QT110H: This part is active-high works in reverse to that described above CIRCUIT GUIDELINES 3.1 SAMPLE CAPACITOR When used for most applications, the charge sampler Cs can be virtually any plastic film or good quality ceramic capacitor ...
