Pololu Magnetic Encoder Pair Kit for 20D mm Metal Gearmotors, 20 CPR, 2.7-18V (Item: 3499)

Pololu Magnetic Encoder Pair Kit (Item 3499) is designed to provide precise position and speed feedback for the popular 20D mm metal gearmotors. This kit is a powerful solution for robotics and automation projects that require accurate motor control, such as a self-balancing robot, a mobile platform, or a robotic arm. Each kit includes two magnetic encoders, which attach to the back of the motor, and two Hall effect sensors that read the magnetic field changes as the motor shaft rotates. With a resolution of 20 counts per revolution (CPR) of the motor shaft, this kit offers excellent feedback for a wide range of control applications. Key Features: Precise Feedback: Provides 20 CPR, allowing for accurate speed and position control of your motors. Easy Integration: Designed specifically for seamless mounting on Pololu's 20D mm metal gearmotors. Dual-Channel Output: The sensors provide two output channels, allowing you to easily determine both the speed and direction of the motor's rotation. Wide Voltage Range: Operates on a supply voltage between 2.7V and 18V, making it compatible with a variety of microcontrollers and power sources. Compact and Reliable: The magnetic design is more robust than optical encoders and fits into a small space, perfect for compact projects.
