GN 414 safety indexing plungers are used when the inadvertent movement of the plunger pin is to be avoided.
The plunger pin is locked in one or both end positions and can be unlocked only via the red safety push button. The push button must be moved in the axial direction.
Locking is automatic once the end position is reached.
The locking mechanism is fully integrated in the operating button, therefore malfunctions caused by dirt or foreign bodies are prevented.
