Optical Rotary Encoder ISC3004 - Discontinued

ID: 3530_0

This encoder can measure rotation at speeds of up to 3000 RPM and plugs into a Phidgets Encoder Interface.

Replaced by 3530_1

Replaced by the 3530_1 - Optical Rotary Encoder ISC3004, the same encoder but with a Phidget encoder cable connector.

This is a small ball bearing construction, rotary encoder without index that goes up to 3000 rpm.

The encoder comes with a 1 meter cable and 2 mounting screws.


This quadrature encoder can be read by an encoder interface. To attach the shaft of this encoder to a motor or some other device, you can use a shaft coupler. See the Connection & Compatibility tab for details.

Encoder Cables


The easiest way to connect your encoder to a Phidgets encoder interface is to use a Phidgets encoder cable, cut it to the desired length and solder the encoder wires to the encoder cable as follows:

Green Brown

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.
