Pololu Magnetic Encoder Pair Kit with Side-Entry Connector for Mini Plastic Gearmotor, 12 CPR, 2.7-18V

This versatile kit is a compact solution for adding quadrature encoding to mini plastic gearmotors. It includes dual-channel Hall effect sensor boards and magnetic discs, delivering a resolution of 12 counts per revolution. The encoder fits snugly within the motor's dimensions, extending slightly to one side, and operates within a voltage range of 2.7V to 18V.

Ideal for robotics and automation projects, this encoder kit enhances precision in motor control, enabling accurate speed and position feedback. By multiplying the gear ratio by 12, users can determine the counts per revolution of the gearbox output shaft, facilitating intricate motion control applications.

The encoders feature a side-entry, 6-pin JST SH-type connector, compatible with various cable options for flexible installation. The single-ended cables have connectors on one end with unterminated wires on the other, while double-ended cables feature connectors on both ends, allowing easy integration with breakout boards and solderless breadboards.

Installation is straightforward: solder the encoder board directly to the motor's back, ensuring alignment by tacking it to one pin before securing the other. The pinout includes connections for power, ground, and quadrature outputs, with built-in hysteresis in the sensors' comparators to prevent false signals.

Compared to previous versions, this module introduces a removable cable connector, maintaining the same electrical performance while offering a lower minimum operating voltage. This improvement simplifies maintenance and upgrades, making it a valuable addition to any motor-driven system.
