Optical Encoder Pair Kit for Micro Metal Gearmotors

Optical Encoder Pair Kit for Micro Metal Gearmotors: 12 or 20 counts per revolution

Your pair of quadrature encoders fit perfectly on the rear of micro metal gearmotors with extended back shafts. You have two pairs of toothed wheels, so to modify the encoder resolution, all you need to do is select either two 3-tooth wheels (12 counts per revolution) or two 5-tooth wheels (20 counts per revolution). Of course, the set also includes two encoder boards, to be soldered behind each motor.

Optical encoders 2590: Fitting precautions

The trickiest part when installing your pair of encoders is undoubtedly soldering your encoder board correctly to the motor, aligning it as accurately as possible so the motor’s back shaft protrudes through the hole in the middle of the board. The signal will be all the better for it, as the toothed wheel is going to be fixed to this protruding shaft, ideally with a gap of 0.5 mm between the wheel and the encoder. It will be possible to connect your encoder at right angles to various components: a PCB, connector, or a series of individual wires. This is an operation best carried out by an experienced electronics technician – especially since decoding the information obtained from the optical encoders also requires a bit of practice!

Note: The two encoders supplied operate from 5 V DC. There is also a 3.3 V version, with a consumption of 24 mA.
