Contacting Single-turn

Contacting Single-turn

A rotary position sensor translates angular mechanical position to an electrical signal. Rotary position sensors are designed for applications that typically require frequent adjustment. Shaftless designs allow for different engagement mechanisms, such as a customized shaft, a motor control, a human interface adjustment or a mechanical arm position locator. Rotary position sensors can be used in applications where a user needs to control a variable output such as a frequency, speed or volume control. Typical applications include test and measurement equipment, consumer electronics, small engines, robotics, and medical equipment. The Bourns® Model 3382 Series uses resistive technology to sense rotary position.
