Optical Encoder Pair Kit for Micro Metal Gearmotors (3.3V)

Optical encoders for micro metal gearmotors: pack of two

This optical encoder kit for Pololu micro metal gearmotors consists of 2 sensors, 2 encoder wheels with 3 teeth, and 2 encoder wheels with 5 teeth.

• Install a 3-tooth wheel on your motor to obtain 12 counts per revolution of the motor shaft
• Opt for a 5-tooth wheel for 20 counts per revolution

To compute the encoder counts per revolution of the gearbox output, multiply by the gear ratio.

Pololu 3.3V micro metal gearmotor optical encoders: some necessary precautions

A certain amount of skill is needed to fix these optical encoders for Pololu micro metal gearmotors, to position the sensor correctly and solder its various pins. The more accurate this positioning, the more accurate and reliable the results.

Also make sure you maintain a space of about 0.5 mm between the encoder and its wheel. And above all avoid overheating the pins of the motor when soldering, as this could damage your motor.
