The One Arm Composite Backshell is specifically designed to offer a robust and unique performance in terms of reliability and functionality for defense, aerospace, and other harsh environment applications. Its design team took into consideration different scenarios and needs for protecting cable connections from damage and providing better strain relief. The One Arm backshell family comes in three types of configurations: Straight, 45º, and 90º. It is designed to satisfy requirements for all sizes of MIL-DTL-38999 Series I, II, and III connectors. The One Arm not only provides unique support and strain relief to open wire bundles, it also offers a reliable grounding option with its solderable ground lug. Due to its flexibility, it can also support different plating combinations to suit the needs required for specific applications. The One Arm is also designed to be economically coat-effective but highly reliable, with high grade thermoplastic materials intended for critical applications and environments, especially on military and commercial EWIS applications that require weight per part savings, corrosion resistance, and electromagnetic interference (EMI) protection.
