Optical encoders for micro metal gearmotors: pack of two

This optical encoder kit for Pololu micro metal gearmotors consists of 2 sensors, 2 encoder wheels with 3 teeth, and 2 encoder wheels with 5 teeth.

  • Install a 3-tooth wheel on your motor to obtain 12 counts per revolution of the motor shaft
  • Opt for a 5-tooth wheel for 20 counts per revolution

To compute the encoder counts per revolution of the gearbox output, multiply by the gear ratio.
