What is a Position sensor?

A position sensor is a sensor that measures the distance, position, rotation angle, etc. of an object. Since the accuracy and detection range differ depending on the object to be measured, it is necessary to select the optimum method from various measurement methods. Position sensor measurement methods include laser sensors, magnetic sensors, capacitive sensors, and rotary sensors. In recent years, 3D position sensors have also been developed and used to measure the posture of robots and the position of fingertips, and there are methods using cameras, lasers, magnetism, etc.
