GN 817 indexing plungers offer the following advantages:

- two retracting strokes (l1) per plunger ?;

- identical small dimensions l for type B and C;

- retracting mechanism (type C) is shrouded in part;

- defined thread length by an undercut at the end of the thread.

Version C with keyed knob is used in all the applications where the plunger must not protrude continually. In that case the

knob is retracted and afterwards turned by 90°. A notch is provided for the key to prevent the plunger from turning by error or

vibration.
