This shape allows better visual orientation of the indexing position of Type C and is advantageous when greater unlocking forces occur. Type C with rest position is used in such applications where the plunger must not protrude continually. In that case the knob is retracted and afterwards turned by 90°. A notch keeps the plunger in this position. see also... • List of Indexing Plunger Types → Page 884 ff. • Positioning Bushings GN 412.2 / GN 412.4 → Page 954 • Distance Bushings GN 609.5 (to Limit the Thread Length) → Page 952 Information • Steel — - - Blackened - - Plunger pin hardened • Stainless steel AISI 303 NI Plunger pin chemically nickel plated • T-Handle Plastic (Polyamide PA) - - Not removable - - Black, matte finish • Load Rating Information → Page 2132 • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4
