Commutating encoder

With six channels, the RCM21 rotary optical encoder is said to eliminate Hall-effect sensors inside of motors. The 2.1-inch diameter encoder simplifies assembly by eliminating Hall sensor alignment. Combining the 3 phase brushless commutation pulses, the 2 data channels (in Quadrature), and the reference (once per revolution) index pulse, the encoder achieves up to 2,000 lines resolution.
