In a linear encoder a magnetic sensor passing over a magnetic scale. So, the type of equipment being analyzed, and how it moves, determines what type of encoder sensor is needed. Absolute encoders use a series of pulses to measure the position and speed of the equipment, whereas an absolute encoder uses bit configurations to directly track positions.

Both types often employ magnetic principles (a magnetic scale or magnetic field) to detect any changes. Linear encoder sensors measure a motion along a linear path, whereas a rotary encoder sensor responds to rotational motion. The difference between the two different types of encoder is the way in which they respond to motion in a given area, and the clue is in their names. ![]() In terms of specific applications, encoder sensors can be found in printers, food processing, robotics, material handling, axis controllers, medical scanners, dispensing pumps, military-grade antennas, drilling machines and telescopes, to name but a few. In recent years, encoders have become a lot more sensitive and tough with higher resolutions at a lower cost, and as a result are now widely used in many industries.įrom an industry perspective, encoder sensors are used across the automotive, consumer electronics, medical, military, manufacturing and scientific instrument industry sectors. It is a device that can provide precise information on the speed, direction and positioning of a piece of mechanical equipment. Here, we look at encoder sensors in more depth.Įncoder sensors have become a widely used class of sensors where feedback information from a moving mechanical system is required. There are two main types of encoder: linear and rotary. ![]() It is an electro-mechanical device that provides users (commonly those in a motion control capacity) with information on position, velocity and direction. Encoder sensors are a type of mechanical motion sensor that create a digital signal from a motion.
