Add Feedback to Your Gearmotor with Magnetic Encoder Pair Kit with Side-Entry Connector for Micro Metal Gearmotors, 12 CPR, 2.7-18V

The Magnetic Encoder Pair Kit with Side-Entry Connector for Micro Metal Gearmotors, 12 CPR, 2.7-18V adds position and speed feedback to matching Pololu motors so your project can move from open-loop control to measured motion.

It is useful for odometry, wheel speed control, closed-loop drive systems, and motion experiments.

Why you'll love it

  • Extended back shaft required (dual-shaft micro metal gearmotor version)
  • Fits within the motor’s 12 mm × 10 mm cross section on 3 sides; extends about 4.2 mm on the 4th side
  • The assembled encoder extends about ~5 mm beyond the plastic motor end cap
  • Closed-loop ready: read speed + direction with quadrature A/B signals for PID control
  • Wide voltage support: sensors run from 2.7V to 18V ; A/B outputs are digital signals
  • Cleaner wiring: JST SH connector lets you use removable cables (great for servicing and modular builds)

What you can build

Use it for wheel odometry, wheel-speed feedback, closed-loop speed control, and motion experiments with supported Pololu motors.
