Product description

With indexing plungers GN 722.4 , the plunger pin is actuated via the pull ring. This is done either manually, with a cable or by means of an extended pull rod with hook. The ST version is designed for applications in steel construction.

The types with lock-out are used when the plunger pin should temporarily not protrude. For this purpose, the pull ring is turned sideways after the locking pin has been retracted. The ring is held in this position by the catch recess at the top of the guide.

The dimensional tolerances between plunger pin and guide are selected so that the functional reliability is guaranteed even after welding, applying a corrosion protection layer, or in case of contamination.

The unassembled types CU / TU are recommended to avoid changing the microstructure of the spring and plunger during the welding process. After welding, the indexing plunger is then assembled.
