The outstanding feature of GN 412 indexing plungers is their compact design. They are mounted either from the front with cyclinder head screws or from the back via the tapped threaded holes. In Type C, the knob can be turned by 30° after retracting the indexing pin, holding it in the "retracted" position by means of the indexing lock.
The dimensions and connection measurements match the combination with GN 412.1 mounting blocks in connection with positioning bushings GN 412.2 or GN 412.3.
