Technical data
Operating principle
Construction
The core of a draw wire device is a
drum mounted on bearings, onto which
a wire is wound.
Winding takes place via a spring-loaded
device. The single-layer wire winding
ensuring the best linearity possible is
a specific feature of Kübler draw wire
encoders.
Note
Exceeding the maximum extension
length of the draw wire will lead to
damage to the wire and the
mechanics.
