They use spread-spectrum modulation for good electromagnetic compatibility performance and low RF emissions. It features drift compensation to account for slow changes due to aging or changing environmental conditions and automatic recalibration for life.

QSlide™ and QWheel™ based products are touch sensors that eliminate the need for conventional resistive sliders or rotary controls. Based on the same charge-transfer technology used for touch buttons in QTouch™, they can be thought of as 'capacitive potentiometers', where the wiper is a human finger.

QSlide™ and QWheel™ products can sense through panels up to 3mm thick. This can be particularly useful in an environment that requires gloved hands. When placed behind glass or plastic, the circuit creates a smooth, indestructible rotary touch control that can replace virtually any mechanical encoder or potentiometer.

It does not require a hole or knob and therefore has no service or maintenance issues.
