B.2 Shield Termination Technique – Method A.1 (Standard)
NOTE
For the following steps please refer to Figure B-l.
1. Attach the Shield Block(s) (Item 2) to the backshell (Item 1) by inserting the flathead screws 
(Item 3) through the holes on the Shield Block and threading into the tapped holes on the backshell 
(Item 1) (see Figure B-1).

2. At one end of a shielded cable (Item 4) measure a distance between “Window Min” to “Window 
Max” (Table B-6) and cut a window (max size 0.35”) in the jacket to expose the shield (Figure B-
2).  Use caution when cutting the jacket to avoid damaging the individual braids of the shield.  
When dealing with a densely populated connector with many cables, it may prove beneficial to 
stagger the windows throughout the “Window Min” to “Window Max” range.  If staggering is not 
needed the “Ideal Window” length is recommended.
Suggested tools to accomplish the window cut:
Coaxial Cable Stripper
Thermal Stripper
Sharp Razor Blade
