Hollow Shaft Optical Encoder IHC3808

ID: 3532_0

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

Replaced by 3532_1

Replaced by the 3532_1 - Hollow Shaft Optical Encoder, the same encoder but with a Phidget encoder cable connector.

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 by fitting the end of the cable with the appropriate connector. 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:

Product Encoder Interface
Image Part Number Price Number of Encoder Inputs Count Rate Max
1047_1B $75.00 4 1E+06 pulses/s
1047_2B $75.00 4 1E+06 pulses/s
1057_3B $50.00 1 1E+06 pulses/s
1065_1B $75.00 1 500000 cycles/s
DCC1000_0 $75.00 1 400000 pulses/s
DCC1002_0 $40.00 1 400000 pulses/s
ENC1000_0 $15.00 1 400000 pulses/s

Encoder Cables

You can easily connect this encoder to a Phidgets encoder interface by cutting the end off of a Phidget encoder cable and soldering the wires to the encoder as described in this table. Below you'll find a list of available encoder cables:

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

Alternatively, you could buy the male connector (Molex part 50-57-9405), and crimp it onto the end of the cable, if you have the appropriate tools.
