D38999/26FJ46SN With quick connection, anti-loose mechanism, EMI/RFI shielding, interface sealing, anti oblique-mating

 

Part number:D38999/26FJ46SN

 

Note:
1. The national military standard GJB599A has the same name as the U.S. military standard MIL-38999K, except that the main name is different, and the rest is identical.
The main name of GJB599A is "J599".
The main name of MIL- dtl-38999k is "38999", which is interchangeable.
2. Identify A,B is used to indicate that the electrical connector USES different contact parts (such as shielding, coaxial, light contact, etc.) which are different from GJB1611 non-standard configuration, and the contact parts need to be placed separately.
