Position sensors are electronic devices that detect and measure the position of an object or system. They are used in a wide range of applications, from industrial automation to consumer electronics. In this article, we will explore what a position sensor is, the problems it solves, applications that use it, technical data, and the main manufacturers.
What is a Position Sensor?
A position sensor is an electronic device that measures the position of an object or system relative to a reference point. There are several types of position sensors, including linear and rotary sensors. Linear position sensors measure the linear distance between two points, while rotary sensors measure the angular position of an object. Position sensors typically use various technologies, such as magnetic, optical, and capacitance, to detect and measure position.
