2-layer, medium resistively-interpolated wheel sensor (n-channels).Įach of these sensors has X (transmit) and Y (receive) electrodes, with the mutual capacitance between X and Y measured by the sensor controller.2-layer, medium/large spatially-interpolated wheel sensor (n-channels).2-layer, medium spatially-interpolated slider sensor (n-channels).1-layer, small spatially-interpolated wheel sensor (n-channels).1-layer, small spatially-interpolated slider sensor (n-channels).The following mutual-capacitance type sensors are supported for use in your PCB designs: Supported Mutual-Capacitance Type Sensors Although they can be used with or without an overlying panel, electrostatic discharge (ESD) implications – for the associated controller device – is a major influence for such a panel being used.Īll of these sensors are suited for use with Atmel QTouch sensor controllers.

Such sensors are non-directional, in terms of their emitted electric fields. A resistively-interpolated sensor uses physical resistors to provide the interpolation.Įach channel (electrode) of these sensors has a single, direct connection to the sensor controller. A spatially-interpolated sensor uses the geometry of its electrodes to interpolate the electric fields. Slider and wheel sensors are one-dimensional sensors – they detect movement of your finger along a single axis. Medium resistively-interpolated wheel sensor (12 channels, only 3 connected to the sensor controller).Ī button (or key) sensor is a zero-dimensional sensor.Medium spatially-interpolated wheel sensor (3 channels).Medium spatially-interpolated slider sensor (3 channels).Small spatially-interpolated wheel sensor (3 channels).Small spatially-interpolated slider sensor (3 channels).Button (or key) sensor (single channel).The following self-capacitance type sensors are supported for use in your PCB designs: Installing Atmel QTouch Touch Sensor Supportįacilitating the use of touch sensor technologies in your board designs, Altium Designer provides support for creating planar capacitive sensor patterns on your PCB, for use with the range of Atmel® QTouch® and QMatrix® sensor controllers.
