Micro Metal Gearmotor Outline Drawing
Also, all metal gears in the gearbox support both forward and reverse rotation (CW/CCW). Engineers build these units with a long-life carbon brush design. Therefore, they deliver steady performance over extended work periods.
Notes: Check the PCB wiring order carefully before powering the unit. Warning: Never swap the VCC and GND connections for the photo encoder, and keep input voltage below 5.0V DC to avoid damage.

COHU PURCHASING –
It was a bit of a challenge to mount the powerful gear motor and wire it up, but with a little bit of tinkering and some electrical know-how, I was able to get it running smoothly. My husband loves it and it’s definitely a great way to get him outside and active. Overall, I’d say it was a worthwhile upgrade.
