QT111 QProx 8-pin Sensor
See QT110 datasheet for primary information. This sheet only lists differences with the QT110.
Description
The QT111 is a touch sensor IC having recalibration timeouts (“max on-duration”) of 5 minutes and infinity.
This allows the device to be used in situations where recalibration timeouts are not desired, for example in
certain consumer, machine tool and process control applications where continuous touch over long periods is
desired, like hand-on-joystick sensors, dead-man switches, etc. Although the primary application of the device
is still as a ‘touch sensor’, longer timeouts also aknowledge alternate uses for the QT110 family, for example in
process controls.
Differences with QT110
The QT111 sensor is exactly the same in all respects to the QT110 with the following exceptions shown in bold

Cautionary Notes
Care should be taken in infinite timeout mode that the Cs and Cx capacitances and the Vcc supply
do not drift substantially over the course of a detection; if any of these parameters change
sufficiently during the course of an active detection (remember: drift compensation is never
performed during a detection event) the sensor can either ‘stick on’ after the detected object is
removed, or, the QT110’s apparent sensitivity will be substantially reduced for a period of time until
drift compensation can recover the proper reference level. If possible, uses the lowest gain setting
when using with long timeouts.
If the sensor ‘sticks on’ after the detected object or substance is removed from the sense element, the only way
to clear the sensor may be to remove power momentarily in order to induce a full recalibration.
