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.
