This Optical Encoder Pair Kit for Micro Metal Gearmotors set includes sensor boards and reflective wheels to add quadrature encoding to two micro metal gearmotors with extended back shafts (motors are not included with this kit). 3-tooth and 5-tooth encoder wheels are included to provide options of 12 counts per revolution and 20 counts per revolution of the motor shaft (to compute the encoder counts per revolution of the gearbox output, multiply by the gear ratio).

Add quadrature encoders to your LP, MP, or HP micro metal gearmotors (extended back shaft version required) with this kit consisting of two sensor boards, two 3-tooth encoder wheels, and two 5-tooth encoder wheels. The installed system does not exceed the 12 mm × 10 mm cross section of the motors and extends only 5 mm beyond the plastic motor end cap. The 3-tooth wheel provides 12 counts per revolution; using the 5-tooth wheel yields 20 counts per revolution.

The encoder boards are available in two versions that are optimized for operation at 5.0 V and 3.3 V. The only difference is in the electrical configuration of the IR LEDs in the reflectance sensors.
