Connection


	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

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.
