Locking Indexing Plungers GN 514

Product description

Information

Locking indexing plungers GN 514 feature a cardioid curve mechanism based on the principle of a retractable pen. They offer very ergonomic operation that requires only repeated pressing of the knob. Thanks to their functional principle, they are well suited for use in tight conditions and are also easy to protect against improper operation, if necessary.

First the plunger pin is brought into the protruding position by pressing the knob. In this position, the cardioid curve mechanism automatically engages to lock the part. Pressing the knob again unlocks the mechanism since the plunger pin retracts automatically by spring force once the button is released. The plunger pin must not be subjected to any axial forces and must move easily.
