Encoders For Micro Metal Gearmotors

Encoders for micro metal gearmotors translate shaft rotation into precise digital signals, enabling accurate speed and position control in compact robotic and automation projects. Both magnetic and optical versions are available, each offering quadrature output that can be read by standard micro‑controller interfaces. The magnetic kits use a Hall‑effect sensor and a small magnetic disc to deliver 12 counts per revolution, while optical kits employ lightweight encoder wheels with multiple tooth counts for higher resolution. All kits are designed for the extended‑shaft version of the motors, providing straightforward wiring through side‑ or top‑entry connectors and ensuring reliable operation across a wide voltage range. Compatibility with low‑voltage logic (3.3 V or 5 V) and the modular sensor boards simplify integration into existing designs.
