A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

Special hardware can overcome software latency that may otherwise negate precise motion control. Precision motion control is virtually never an end in itself. Rather, it ties position to other events ...

These IXARC magnetic encoders withstand harsh environments and are modular for maximum versatility. Rotary encoders measure the rotation of machine shafts and report the results to electronic controls ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...
