Related options: J599/20FE26PN uses electroless nickel finish (F); J599/20WE26PN uses olive drab cadmium (W); socket versions use S contacts; jam-nut style is J599/24KE26PN; mating plug is typically J599/26KE26SN. Same shell size also commonly uses arrangements E2, E6, E8, E35, and E99. There is no functional difference between J599 and D38999 prefixes for form-fit-function mating within the same Series III family.
Compatible Applications
The J599/20KE26PN square flange receptacle is intended for platforms that require EMI-capable threaded interconnects with mid-count #20 circuits and stainless Class K corrosion performance. Typical use cases include:
- Aircraft and helicopter wiring harness panel interfaces
- Avionics LRUs, radar, and communication equipment
- Ground vehicles and rugged electronic enclosures
- Marine / outdoor equipment requiring high corrosion resistance
- Industrial systems that standardize on GJB599 / D38999 Series III interfaces
