Here is a gearmotor consisting of a 4-stage planetary gearbox and a RS775 series motor. The motor has been updated to include an encoderalready mounted. The motor with pinion (am-2765) can be purchased separately, if needed.
This product has the same output shaft geometry (10mm with a 4mm keyway) as our other PG series gearmotors (PG27, PG71).
We also have a convenient bracket (am-2197, not included) which can mount this motor.
Specifications:
Physical Specs:

Encoder:
- Pulses Per Revolution: 7
- Operating Voltage: 5VDC
- Pinout:
- Pin 1: 5Vdc
- Pin 2: Gnd
- Pin 3: Encoder Output Cha. A*
- Pin 4: Encoder Output Cha. B*
* Note: Because the encoder is connected to the back of the motor shaft, the rotation is backwards from normal front mounted encoders so you will need compensate for this in software or simply connect Ch. A output to your Ch. B input and Ch. B output to your Ch. A input.
