Information

Flange: Aluminum, black anodized
Reference arrow: White laser engraved
Clamp ring: NBR synthetic rubber
Friction ring: Technopolymer (Polyamide)


GN 723.3 reference flanges are used together with GN 723.4 control knobs, which offer the following advantages:
They have a reference mark to line up with the control knob scale.
They give additional support to the control shaft.
They can be fitted with end stop pins to limit the angular movement of the control knob (the introduction of rest positions with the aid of ball plungers is also possible).
The version with friction ring prevents unexpected movement due to vibration.
