Additional Details

The D38999/20FC04SN connector features a threaded coupling mechanism that ensures a secure and vibration-resistant connection. Its aluminum alloy shell provides excellent strength and shielding against electromagnetic interference (EMI). The cadmium over electroless nickel plating offers corrosion resistance, making it suitable for use in marine and other harsh environments. The socket contacts are designed for solder termination, providing a robust and reliable connection to wires or cables. This connector is designed to meet the stringent requirements of military and aerospace applications, ensuring reliable performance in critical systems. The specified contact arrangement is ideal for power and signal transmission. The cadmium plating offers excellent corrosion resistance but newer versions using RoHS compliant platings like Zinc-Nickel are becoming more common. Always check current regulations and application requirements before using components with cadmium plating.
