The GN 612.8 are cam action indexing plungers for use in various applications, especially in situations when the locking pin must not protrude all the time. Users can rotate the lock through 180 degrees, which will make the locking pin withdraw itself.
In addition to this, safe positioning is allowed by the notch, while the cam indexing plungers in this product series are reasonably priced and come with design versions that are made of die-cast zinc, which adds durability.
