Information
GN 617.1 indexing plungers with lock-out are used for applications where the plunger pin needs to stay
in its retracted position. To achieve this, the knob is rotated by 90 degrees after being retracted. A notch
keeps the plunger in the retracted position.
The indexing plungers completely made of stainless steel parts are a good choice for use in corrosion
free environments.
