Ideal for use with motors, this hollow-shaft encoder fits easily onto an 8mm shaft. The index channel makes it easier to find the orientation of the motor on startup.

Hollow Shaft Optical Encoder IHC3808






Ideal for use with motors, this hollow-shaft encoder fits easily onto an 8mm shaft. The index channel makes it easier to find the orientation of the motor on startup.






This sturdy optical quadrature encoder can be attached to the 8mm rear shaft of a motor without need for a shaft coupler. It has 360 counts (full quadrature cycles) per rotation and can be installed easily by fitting it over the shaft and tightening the set-screw. This encoder makes use of the index channel, sending one pulse for every full rotation.

This rotary encoder connects to:

  • 1057 - PhidgetEncoder HighSpeed
  • 1047 - PhidgetEncoder HighSpeed 4-Input

  • The easiest way to connect your encoder to the 1057 or to the 1047 is to use a 3019 - HighSpeed Encoder Cable 50cm, cut it to the desired length and solder the encoder wires to the encoder cable as follows:

    Function 3532-Encoder 3019-Phidget cable
    +5V Red Red
    Ground Black Black
    Data (A) Green White
    Data (B) White Brown
    Data (B) Yellow Green
    FUNCTIONAL

    You could also buy the male connector, which is a Molex 50-57-9405, and crimp it onto the end of the cable, if you have the appropriate tools.
