Hollow Shaft Optical Encoder IHC3808

ID: 3532_1
Recommended for new designs: This product is sourced from another supplier, but it (or a similar replacement with a compatible form, fit and function) is estimated to be available for as long as it is available from the supplier.

Ideal for use with motors, this hollow-shaft encoder fits easily onto an 8mm shaft.

Note: The 3532_1 is the same as the 3532_0, except this revision has a 5-pin connector soldered to the end of the cable so it can be plugged directly into a Phidgets encoder interface.

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.

Comes Packaged With

  • Mounting screws and washers


This quadrature encoder can be read by an encoder interface. See the Connection & Compatibility tab for details.

Encoder Interfaces

This quadrature encoder must be read by an encoder interface. These interfaces will interpret the two quadrature signals in order to determine the continuous position of the rotating part. The following interfaces are compatible with this encoder:
