Draw Wire Encoder (0.6m)

ID: ENC4106_0

Like a digital tape measure, this 600mm draw wire encoder measures the length of wire pulled out of it.

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 M4 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.

Encoder Interfaces

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:
