Information
GN 612 cam action indexing plungers are best utilized in applications where the pin may need to be
retracted periodically. By rotating the lever arm 180° the plunger pin is withdrawn. The notch allows for
safe positioning while the plunger pin is held in the retracted position.
The grooved lever arm provides the user with a better grip when operating the mechanism. In addition,
the snap-on plastic ribbed sleeve offers a more aesthetically pleasing and comfortable finger grip.
