(American standard 303), chemically nickel plated
Knob: Matte black technopolymer plastic (Polyamide PA), not removable
Indexing plungers GN 607.3 are designed for
installation in thin walled equipment. They are used in applications
where the plunger does not always need to protrude. To achieve
this, the knob is rotated by 90 degrees after being retracted.
The head of the plunger body features a notch in the opposite
position which prevents the plunger from accidentally slipping
back into its forward position.
Depending on the mounting plate thickness "s," the
protruding plunger length "l1," and the postion
of the hexagon nut on its center bushing, the plunger nose
might not always be fully retractable.
For design reasons the positional accuracy of this indexing
plunger is not as precise as GN 607.
Double ring spanner wrench GN 607.9 (1 mm thick zinc plated
sheet steel) for installation is available upon request.
Maximum heat resistance of nylon plastic hand knob: 110°C (230°F).
