The dimensions correspond to those of the GN 617 or GN 617.1 indexing plungers. Type C / CK with rest position are used for such applications where the plunger has 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 this position. see also... • List of Indexing Plunger Types → Page 884 ff. • Mounting Blocks GN 412.1 → Page 956 • Distance Bushings GN 609.5 (to Limit the Thread Length) → Page 952 • Indexing Plungers GN 617 (Steel / SST, without rest position) → Page 892 • Indexing Plungers GN 617.1 (Steel / SST, with rest position) → Page 893 Information • Threaded body Plastic (Polyamide PA-HP) - - Glass fiber reinforced - - Temperature resistant up to 130 °C - - Black, matte finish • Plunger pin - - Steel ST Hardened, blackened - - Stainless steel AISI 303 NI • Pressure spring Stainless steel AISI 302 • Knob Plastic (Polyamide PA) - - Black, matte finish — - - Red, RAL 3000, matte finish RT - - Not removable • Lock nut Plastic (Polyamide PA-HP) Black, matte finish • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 1 d 1 2 Type 3 Material How to order (Plunger pin steel, knob black) 1 2 3 GN 617.2 -6-BK-ST 1 d 1 2 Type 3 Material 4 Color How to order (Plunger pin stainless steel, knob red) 1 2 3 4 GN 617.2-8-C-NI-RT 4 Original design PMT.100
