GJB599 Series Circular connector

The GJB599 series is designed for systems requiring rapid disconnection under blind conditions. These connectors are engineered to withstand high-intensity vibrations and, when paired with appropriate accessories, are suitable for use in harsh environments with sand and moisture.

Connection methods:

  • Series I (JY27467/JY27496): Quick latch connection (pins on the socket slide into the corresponding spiral slots of the plug connector)
  • Series III (J599/26FD35SN, J599/20FD35PN): Three-point thread quick connection with a ratchet locking mechanism (anti-loosening device)

Key product features:

  • Contact form: Crimped wire (contact is designed for rear extraction and insertion)
  • Casing anti-misalignment: Five-key anti-misalignment (N, A, B, C, D)

Product execution standards:

  • GJB 599B ‘General Specification for Environmentally Resistant Quick-Disconnect High-Density Miniature Circular Electrical Connectors’
  • GJB 2293A ‘Dimensions and Requirements for Contact Mating of Electrical Connectors’
  • GJB 2292A ‘Dimensions and Requirements for Accessories Mating of Electrical Connectors’
  • GJB 1611 ‘Arrangement of Contact Holes for Insulation Installation Plates of Environmentally Resistant Quick-Disconnect High-Density Miniature Circular Electrical Connectors as per GJB599’
