In complex mechanical systems, it is often very difficult to accurately measure the movement of a single part, particularly if it has several degrees of freedom. The draw wire encoder is a versatile solution to this very problem; it can be attached to a part using an M5 screw or fastened to the end with a zip tie, and the encoder itself has a pair of M5 screw threads on the back for easy installation.
When the wire is pulled out, the sensor produces a quadrature signal to describe the length of wire exposed. The reel is spring loaded, so it will retract when there is no tension in the wire. Multiple draw wire sensors could be used to track the position in more than one dimension.
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.
This draw-wire 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 draw wire. The following interfaces are compatible with this encoder:

You can easily connect this draw-wire 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:
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.
