Notes: 1. Except for the different main designations, the model naming of GJB599A (National Military Standard) and MIL-DTL-38999K (U.S. Military Standard) is identical. The main designation of GJB599A is "JY", and that of MIL-DTL-38999K is "MS"; the two are interchangeable and compatible.
2. Identification Numbers A and B indicate that the electrical connector uses non-standard contacts different from GJB1611 (such as shielded, coaxial, fiber optic contacts, etc.). Such contacts need to be ordered separately; specific models and specifications are shown in "Special Contacts for GJB599 Series III".
3. For information on compatible sealing caps, rear accessories, and square flange gaskets of this series, see Pages 71-84.
