Encoder sensors are used in a variety of applications, including printers, food processing, robotics, material handling, axis controls, medical scanners, dispensing pumps, military-grade antennas, drilling machines, and telescopes, to mention a few.
The difference between the two sorts of Encoder is how they respond to motion in a specific location, and the key is in their names. Linear encoder sensors detect motion along a straight line, whereas rotary encoder sensors detect circular motion. To detect changes, both types frequently use magnetic principles (a magnetic scale or magnetic field). The sensor detects changes in the magnetic field or magnetic location and produces an output that reflects a change in speed, position, or direction.
Each sensor class is further subdivided into absolute and incremental sensors. Absolute encoders use a series of pulses to measure the location and speed of the equipment, whereas absolute decoders track positions directly using bit configurations. Hence, the sort of encoder sensor required is determined by the type of equipment being evaluated and how it moves.
