Micro Metal Motor Encoder (MMME) - module with an encoder for micro (side) motors - 2 pcs.

This is the Wheel Encoder Kit from DAGU, a simple add-on to any wheeled robot that can help measure the speed or distance the chassis travels. ROB-12629

Set of two magnetic encoders for use with micro motors. Regular mounting, set of 2. Pimoroni PIM604

This encoders are designed for DFRobot 3PA and AWD Rovers. It can give you the rotation degree of the wheels. Encoder uses non-contact method to convert the angular displacement signals. Best fit with Micro DC Geared Motor. SEN0038

Magnetic disk for use with magnetic encoders designed for Pololu 20D series motors. It allows you to generate 12 pulses per revolution. Pololu 3449

AB two-phase pulse wave, measured by two infrared reflective sensor. These two sensor pulse waveform is close to a phase difference of 90 degrees, through the AB two-phase lead and lag of the waveform judged wheel forward rotation or the reverse. SEN0116

A set of two magnetic encoders for use with Pololu DC Micro motors. The maximum resolution is 12 pulses per one revolution of the motor shaft. Powered from 2.7V to 18V. Pololu 4761

Add quadrature encoders to your 20D mm metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and Hall effect sensors to provide 20 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.

A set of magnetic encoders for the Romi Chassis chassis. With their help, we can measure the distance traveled by our mobile robot or control the engine speed. Pololu 3542
