Magnetic Encoder Pair Kit for Micro Metal Gearmotors, 12 CPR, 2.7-18V (old version)

Pololu item #: 2598

This product has been discontinued.

This has been replaced by a functionally identical new version with enlarged the motor terminal holes that are compatible with all our micro metal gearmotors (including the newer HPCB ones).

Add quadrature encoders to your LP, MP, or HP micro metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit.

Note: This version is not compatible with the HPCB micro metal gearmotors; it is only compatible with LP, MP, and HP dual-shaft micro metal gearmotors.
