Seven Styles of Non-Environmental Conical Shield Ring Type EMI/RFI Backshells
The right style of shield termination for every EMI/RFI application
A choice of 360° shield/screen terminations are offered in straight and angled backshells, including designs to accommodate combinations of individual or overall shields or screens. All designs included in this section provide low dc resistance across the termination area. Selection is based primarily on cable construction—what type of shield is being terminated, where the shield or combination of shields is located within the cable and the type of outer jacketing are key variables.
For assistance in selecting the right style of conical shield ring backshell for your application please review the following type descriptions and assembly instructions, or call our factory for assistance.
Reference
Type A Assembly Instructions
For heavy and medium duty applications, an EMI/RFI backshell which features two tapered conical rings which capture the overall cable/harness shield inside a counterbore in the backshell body. Shield "WALL" thickness range: 0 to .062 (1.6mm).

Type B Assembly Instructions
A medium or general duty design which accomodates either an overall cable/harness shield, or shields or ground wires from individually shielded complexes, or both simultaneously. A tapered ground ring which seats into a corresponding tapered surface in the backshell affords full peripheral termination. Shield "WALL" thickness range: .031 (0.8mm) to .188 (4.8mm).

Type C Termination
Two versions: medium and light duty shield termination designs which have a tapered grounding ring mating to a tapered surface on the rear of the backshell for 360° shield termination of an overall braided shield. Light duty termination designs are specifically configured for weight-sensitive applications. Shield "WALL" thickness range to max of .062 (1.6mm).

Type E Assembly Instructions
This is a light duty termination for either overall or individual shield termination or both. Two or three ground rings are utilized, the two ring style can be used for grounding either individual or overall shields. For grounding both individual and overall, the three rings style is used.
