GN723.4 Control Knob, Aluminium
These control knobs are an accurate means of making fine, precise position adjustments.
Both scale and reference marks on the control knobs are indelibly marked and easily legible. These control knobs can be supplied blank, with standard scale, or with custom graduation markings.
They can also be combined with reference flanges GN723.3 to offer the following advantages:
- The flange has reference markings relating to the control knob scale, allowing accurate alignment.
- They give additional support to the control shaft.
- They can be fitted with end stop pins to limit the angular rotation
- The friction ring version prevents unexpected movement through vibration.
An additional surcharge applies for custom graduation. If this is not chosen on the original order, this will be invoiced separately.
Aluminium AL, anodized, natural colour.
Scale (type S) and arrow (type M), engraved with laser precision.
Grub screw DIN916 - Stainless Steel NI, with internal hexagon and with serrated point.
Custom graduations are available in various designs. See further details on Custom Graduations for designs and prices.
