Product description

Control knobs EN 957.1 are used in conjunction with digital position indicators when a control knob is to be used for adjustment. The diameter d₂ is coordinated to the hollow shaft diameter of the relevant position indicator.

The set screw of the digital position indicator must be replaced by a longer set screw enclosed with the control knob in order to clamp the adjusting shaft.

The control knob is then placed on the hollow shaft of the digital position indicator, with the newly inserted set screw in the recess of the control knob serving as a swivel limiting stop.

With the aid of the second set screw d₄, the control knob then is axially fixed on the hollow shaft of the digital position indicator with the recommended torque M_A.
