Encoder for Pololu Wheel 42x19mm

Pololu item #: 1217
Brand: Pololu

This product has been discontinued.

We have released a newer encoder solution for our micro metal gearmotors that provides many more counts per revolution and does not put any restrictions on the gearbox output shaft. This older encoder set is now only available by large-volume special order; please contact us for more information.

This quadrature encoder works with our micro metal gearmotors, 42×19mm wheel, and extended bracket to measure the rotation speed and direction of the wheel. With twelve teeth on the wheel, the system provides a resolution of 48 counts per revolution, which corresponds to a linear resolution of just under 3 mm or 1/8″
