By rotating the lock through 180° the locking pin withdraws itself. A groove keeps the plunger in this position. The square body can therefore be welded in any required position. In order to prevent a change in the spring load by the transferred heat we recommend spot welding the plunger body. see also... • List of Cam Action Indexing Plunger Types → Page 958 ff. • Positioning Bushings GN 412.2 / GN 412.4 → Page 954 Information GN 612.3 Cam Action Indexing Plungers Steel / Stainless Steel for Welding 3 Type A Without plastic cap B With plastic cap • Steel — - - Guide blackened, weldable - - Plunger pin nitrided • Stainless Steel NI - - Guide, weldable AISI 304 - - Plunger pin AISI 303 • Pressure spring Stainless steel AISI 301 • Cap Plastic (Polyamide PA) 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 1 d 2 s 3 Type How to order (Steel) 1 2 3 GN 612.3-10-16-A 1 d 2 s 3 Type 4 Material How to order (Stainless steel) 1 2 3 4 GN612.3-8-20-B-NI
