Plunger pin moving only after operating the safety push-button

Elesa+Ganter, makers of standard machine elements, have enlarged their
indexing plunger range by adding “safety indexing plungers”.
The GN 414 safety indexing plungers are recommended for operations
where the inadvertent or careless movement of the plunger
pin must be avoided.
In its basic design (Type A), the plunger pin is locked in the lower
protruding position and unlocked only by operating the red safety
push-button.
In design variant Type B, the plunger pin is locked in the top
retracted position and is also unlocked only by operating the red
push-button.
Type C features a locking mechanism at both end positions.
As the locking mechanism in all design variants is fully integrated
in the operating button, malfunctions caused by dirt or foreign
bodies are virtually ruled out.
The GN 414 safety indexing plungers are made of burnished steel
with a grey-black plastic operating button which is temperature
resistant up to 80°C. The operating button cannot be removed.
The safety push-button is made of red plastic.
These indexing plungers are available with and without lock nut.
Depending on conditions (e.g. wall thickness), the thread length of
the GN 414 safety indexing plunger can be adjusted using distance
bushings (GN 609).
