Incremental rotary encoders are multi-turn sensors that use optical, mechanical, or magnetic index-counting for angular measurement. They contain no absolute reference, but instead count relative to the turn-on position.
Joystick controllers use potentiometric, inductive or photoelectric sensing systems and/or switches to translate joystick motion into an output signal.
Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core
Position probes measure the position of a target surface, usually with a high degree of accuracy. This search form covers many different linear position products.
Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.
