Y27473T18F32SN MIL‑DTL‑38999 Series II 32Pin Circular Aviation Connector，Circular Connector, 32 Pin, Defense‑Grade Standard, Quick Lock, EMI Shielding
Product Details
This product complies with GJB599B (MIL-DTL-38999M) Series II standard and adopts card-type quick connection structure.
It ranks the smallest in volume, lightest in weight and shortest in housing among all 599 series, and supports EMI/RFI shielding performance.
The contacts are press-fit and detachable, and diagonal insertion is not allowed. In narrow space where insertion and removal are inconvenient, it is recommended to pre-install pins in the socket.
This product is applied to circuit signal connection.
This is a lightweight electrical connector, suitable for working conditions without high-intensity vibration, severe wind, sand and humid harsh environments.
