Page 970 | 3.1 Indexing, Locking, Blocking with Pins and Ball-Shaped Elements GN 722.3 Spring Latches Steel / Stainless Steel with Flange for Surface Mounting, Parallel to the Plunger Pin 3 Type L Left indexing cam R Right indexing cam With spring latches GN 722.3, the plunger pin is retracted over the curve of the guide by a 180° turn of the latch. The notch at the upper end of the curve causes the latch to be held in place if the plunger pin needs to be kept temporarily from protruding. The ZB and SW versions are designed for applications in steel construction, whereas the A4 stainless steel ver- sion is suitable for use in particularly aggressive environments. The dimensional tolerances between the pin and the guide have been chosen to ensure functional reliability even in roughly dimensioned ap- plications or in the event of soiling. For fastening, slotted or hexagonal mounting holes allow the use of socket cap screws DIN 912 and hexagon screws or nuts according to DIN 931 or DIN 934. see also... • List of Cam Action Indexing Plunger Types → Page 958 ff. • Positioning Bushings GN 412.2 / GN 412.4 → Page 954 • Cam Action Indexing Plungers GN 612.2 / GN 612.9 → Page 968 / 969 Information • Guide Steel precision casting - - Zinc plated, blue passivated ZB - - Zinc plated and powder coated Black, RAL 9005, textured finish SW - - Latch Zinc plated, blue passivated - - Plunger pin Steel, zinc plated, blue passivated - - Pressure spring Stainless steel AISI 316Ti • Guide / Latch Stainless steel precision casting A4 AISI 316 - - Plunger pin Stainless steel AISI 316 - - Pressure spring Stainless steel AISI 316Ti • Load Rating Information → Page 2132 • Stainless Steel Characteristics → Page 2166 • RoHS 1 2 d 1 Pin  −0,05 −0,25 Bore  +0,1 +0,3 s b +0,3 d 2 +0,2 h 1 h 2 h 3 k 1 k 2 k 3 l 1 ≈ l 2 l 3 l 4 l 5 m A/F Spring load in N ≈ Initial End  8 20 6,1 6,1 7,5 1,5 10 7,5 18 12 54 14 35 37 48 34 10 15 50 10 20 6,1 6,1 7,5 1,5 10 7,5 18 12 54 14 35 37 48 34 10 15 50 12 20 6,1 6,1 7,5 1,5 10 7,5 18 12 54 14 35 37 48 34 10 15 50 14 20 6,1 6,1 7,5 1,5 10 7,5 18 12 54 14 35 37 48 34 10 15 50 16 30 10,1 10,1 15 5 15 14 34 10 83 20 54 55 80 55 17 30 110 20 30 10,1 10,1 15 5 15 14 34 10 83 20 54 55 80 55 17 30 110 1 d 1 2 s 3 Type 4 Finish / Material How to order 1 2 3 4 GN722.3-20-30-L-ZB Specification 4
