This paper will discuss a variety of rotary position feedback sensors including digital, contacting analog, and non-contacting analog, and may act as a high- level guide to selecting the right sensor for a given linear actuator design.
Linear actuators are employed in virtually every type of electro-mechanical device requiring linear motion. These pervasive designs are integral to all types of industrial automation equipment, machine tools, robotics, medical imaging and diagnostic devices, solar equipment, automotive parts, computer peripherals such as disk drives and printers and test and inspection applications. Typically, they are designed to be used in conjunction with motors, valves, pumps, switches and dampers.
