J599S5 Lightweight Miniature 38999-Type Circular Connectors
Up to 41 % lighter · same insert arrangements as Series III · 2 to 128 contacts

IP67 · push-in quick connect · ≈ 50 % lighter than Series III
XY1 is a push-in (straight-plug) miniature circular connector for equipment where space, weight and cost are constrained. It is sealed to IP67 and, compared with a GJB 599 Series III connector with the same layout, about 50 % lighter and 60 % smaller. Contacts are removable, and contact counts can be customized.

XY1 is a push-in connector: push the plug straight in to mate; no coupling nut to turn. It is sealed to IP67.
Yes. More layouts are being added, and contact counts can be customized to your requirements.
Part number, drawing, pin-out or a short description of your application.
Our engineers match the configuration and reply with a drawing and quotation.
Samples are built to order. The minimum order quantity is 10 pieces, and samples and production orders each take 4–8 weeks. Third-party testing to your specification is available on request.
You test the samples in your own equipment and approve them.
Production follows the approved sample configuration, with machining, molding, plating and assembly in our own Shenyang factory.
