What are Encoders?
Encoders are electro-mechanical devices that converts the angular position of a shaft or axle to an analog or digital signal.
There are two main types: absolute and incremental (relative). The output of absolute devices indicate the current position of the shaft. The output of incremental devices provide information about the motion of the shaft, which is typically further processed elsewhere into information such as speed, distance and position.
Photoelectric encoders convert working parts (machine tools, robots, etc.); angular or linear displacements into electrical signals containing information about the magnitude and direction of the displacement. After further signal processing by the numeric control devices (processor complexes, digital read out devices), this information is then used to control moving parts.
An Incremental encoder will immediately report changes in position, which is an essential capability in many applications. It is a is a linear or rotary electromechanical device that has two output signals, A and B, which issue pulses when the encoder is moved.
An encoder is commonly used in machine tools and other devices that rely upon accuracy and precision.
ORLIN are able to supply bespoke units or parts to fit your existing system, or to provide a complete solution. Our encoders are manufactured by several different suppliers and we will help you choose the correct one for your application.
