Procurement Notes

Verify that the target connector interface matches MIL-DTL-38999 Series III or IV standards before procurement. Confirm that the shell size requirement corresponds exactly to size 28 to ensure mechanical compatibility. Check that the cable diameter falls within the specified range of 0.610 inches to guarantee proper fitment of the banding strap. Ensure environmental specifications align with the cadmium-plated aluminum construction requirements.

Selection Notes

Select this model when a robust, self-locking strain relief solution is required for high-reliability military applications. The choice depends on the need for a 180-degree cable exit configuration combined with the mechanical security of a banding strap. Consider the aluminum material properties and cadmium finish for corrosion resistance in demanding operational conditions compared to alternative plastic or stainless steel options.
