Closed loop systems use feedback signals for stabilization, speed and position information. A feedback device’s primary function is to transform physical parameters into electrical signals for use by a motion controller.
There are many types of feedback devices. For example, rotary shaft encoders are electro-mechanical devices that convert a mechanical input into electrical signals. These signals on the motion of a shaft are typically further processed into information such as speed, distance, RPM and position by counters, tachometers, and programmable logic controllers (PLCs). Rotary encoders are used in many applications that require precise and unlimited shaft rotation, such as industrial controls and robotics.
Feedback devices are precision instruments that are often used in rugged production circumstances. Therefore, engineering, fit and quality are critical when it comes to finding the right feedback devices.
