Wire-actuated encoder - SIKO - #7

7 Mounting note When attaching the wire it should be pulled out straight in line with the wire outlet. initial position final posotion~5mmmeasuring rangemax. extension length Recommendation: A 5 mm wire extension is recommended before the measurement starting point. This prevents the wire snapping back to the stop on rewinding. Mounting example Guide rollers are used wherever the wire-actuated encoder can-not be installed in line with the extension direction of the wire. Several rollers can be used to redirect the wire without influenc- ing the measurement result. An opening slightly larger than the diameter of the wire is suf-ficient as a point of access at measurement sites which are hard to reach. A protective cover is recommended for use in soiled environments. Note: Mechanical stress shortens the lifespan of the wire.A wire extension piece can be used for applications where the distance between the wire-actuated encoder and the measure- ment range is greater than the wire’s maximum extension length. This does not extend the actual measurement range, however (see above: mounting note). This simple method is useful for measurements in areas where a suciently large distance is required between the wire-actuated encoder and the measured object due to high temperatures, harsh environ- ments, measurement in liquid media, areas which are dicult to access, etc.Detailed information on guide rollers or wire extension pieces can be found on the product page in the accessories section. 3 . 1 3 . 23
