It can be operated manually or in Type D and DK mechanically (pneumatic cylinder, cam plate, etc.) when it will protrude only as long as it is operated. Using the internal thread at identification 2 on the pressure side, special pressure bolts or a rod arrangement can be operated, for instance. The screw drivers GN 613.1 (available as accessory) shorten the assem- bly time and make it easier to hold the mechanism in place while fixing the lock nut. The screw driver is inserted in the side between the knob and guide, where it engages the slot in the guide. see also... • List of Indexing Plunger Types → Page 884 ff. • Spring Elements GN 513 → Page 998 Information • Guide (Threaded socket) - - Steel, blackened ST - - Stainless steel AISI 303 NI • Plunger pin Stainless steel AISI 303 Chemically nickel plated • Knob plastic (Polyamide PA) - - Black, matte finish - - Not removable • Load Rating Information → Page 2132 • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4 • Screw Drivers GN 613.1 (Code no. see table) Accessory
