The encoder is mounted on the motor.

The sensors work only withmicro Pololmotorsequippedwith a double-sided, extended shaft.

The principle of operation of the encoders.

Encoder outputs

The board is equipped with M1 and M2 connectors to solder the motor contacts and a 6-pin socket adapted to JST SH connectorwith a1 mmgrid.M1 and M2pins are used to power the motor, the other four pins are used to power the sensor and access the quadrature outputs. TheVCC and GNDpins are used to power the sensor, whileOUT A and OUT Bare digital signals, supplied with low voltage (0 V) or pulled to VCC by a10 kΩresistor,dependingon the magnetic field. The comparators have a built-in hysteresis which prevents false signals when the motor stops near the transition point.
