Pair of Pololu 12 CPR, 2.7–18V Magnetic Encoders for Micro Metal Gearmotors (HPCB compatible)

A pair of 12 CPR, 2.7–18V magnetic encoders for your Pololu micro metal gearmotors

These magnetic encoders for Pololu micro metal gearmotors each consist of a 6-pole magnetic disc and two dual-channel Hall effect sensors. Magnetic disc rotations are converted into digital signals sent to your programming board or motor driver, at a resolution of 12 counts per revolution. First solder the M1 and M2 pins directly to your motor. Then solder 6 individual cables, a ribbon cable or a 6-pin header to the 6 output pins of each encoder.

Need help mounting your encoders for Pololu micro metal gearmotors?

The Pololu micro metal gearmotor encoders are compatible only with micro metal gearmotors that have an extended output shaft. It passes through the hole in the middle of the encoder, and the magnetic disc is attached to the end of this shaft extension. It is recommended that you solder the M1 pin first before carefully positioning the encoder on its shaft, and then solder the M2 pin afterwards. Given the configuration of the system once installed on its micro metal gearmotor, it is impossible to use a conventional 2.54 mm header. You can use a 2 mm male header provided it is fixed at an angle that does not prevent the magnetic disc from rotating when the pins are pointed in the direction of the magnetic disc.
