J599 Series III Circular Connectors (38999 Series III Type)
38999 Series III type · shell sizes 9–25 · 184 insert arrangements
ZH83723 Circular Connectors (MIL-C-83723 Type), to +260 °C
83723 type · 65 dB shielding · to +260 °C
ZH83723 connectors are built to GJB 4337 (MIL-C-83723 type) in classes A, K, R and Y. A self-sealing grommet with triple-ridge holes seals every wire, O-rings and an interfacial seal close the mating face, and an anti-decoupling device keeps the plug locked. Stainless-steel K versions are fire resistant; Y versions are hermetic.
