Folgendes liest man auf den Seiten von Phidgets:
The 3269 is a 24 volt gear motor, generating 5.1 Kg-cm of torque at 588 RPM. It's a large motor that provides lots of torque, even at higher speeds.
The planetary gearbox on this motor is more sophisticated than a typical spur gearbox and will provide greater efficiency, higher torque, and quieter motor operation.
This revision of the 3269 has had its rear shaft and mounting holes changed to be compatible with the 3531 - Optical Rotary Encoder HKT22.
Also nix neues und falsches ...
