Product Introduction
Compliant with GJB599B (MIL-DTL-38999M) Series II standard. Adopts card-type quick connection design. It features the smallest volume, lightest weight and shortest housing length among all 599 series products.
It provides excellent EMI/RFI shielding performance. The contacts are press-fit and detachable with anti-diagonal insertion structure. For limited space where plugging and unplugging is inconvenient, it is recommended to pre-install pins into the socket.
Purpose: This product is used for circuit signal connection.
Application environment: This lightweight electrical connector is suitable for occasions without high-intensity vibration, severe wind, sand and humid harsh conditions.
