Material: Stainless steel 1.4305 (AISI 303), plunger pin
nickel-plated. Knob: Plastic Thermoplast (polyamide) black, matt finish,
cannot be disassembled.

Indexing plungers 817 offer the following advantages: – small outer
dimensions – most of the release mechanism (version C/CK) is covered –
defined thread length by an undercut at the end of the thread (version
G/GK).

Version B/BK: with knob, without notched catch, this version is
used where, on releasing the knob, the plunger pin should be returned to
its initial position by the spring force.

Version C/CK: with knob, is used if the plunger pin has to remain
in retracted position. To achieve this, the knob is rotated by 90
degrees after being retracted. A notched catch stops the locked-in knob
from returning to its initial position accidentally or due to vibration.

Version G/GK: with threaded plunger end, for applications where a
special knob to customer¿s request is required or where the plunger pin
is not shifted manually.
