4.2.2 Dowel pin
Simultaneous rotation of the measuring system, caused by the resulting torque, is
prevented by a dowel pin on the machine side. The measuring system has a 6 mm
deep 4K7 groove insertion on the back to hold the dowel pin. The dowel pin must
reach at least 4 mm into the groove insertion.
Fig. 6: Using a dowel pin to prevent simultaneous rotation
When inserting the measuring system, position it so that the dowel pin is seated
correctly in the groove insertion. By tightening the clamping ring with the Allen key, the
measuring system is protected against slippage on the shaft.
