Sunbank’s Single Arm backshell is designed to withstand 50% greater bending moment than standard AS85049 composite options. This product is up to 40% lighter than aluminum. Reducing weight will positively impact the overall mass of the electrical system, reducing the fuel consumption of the aircraft. Sunbank has designed the Single Arm Series to be the strongest of its kind, while also obtaining the maximum weight depletion achievable.
The Single Arm backshell series is designed to offer strain-relief and damage protection to cables and harnesses, while also ensuring maximum weight saving. Engineered for civil and military EWIS applications, the Single Arm has many benefits compared to its die casted metallic version. The high-grade thermoplastic composite material is not prone to electromagnetic disturbance, “stealth ability”, and presents a higher resistance to vibrations due to reduced harmonic resonance because of the weight reduction.
Single Arm technology also offers the advantages of detent self-locking, a ratcheting coupling ring using non-corrosive clips inside. The audible ratcheting noise generated during the coupling process ensures a safe usage. The backshell is available in 3 versions: Straight, 45° and 90°.
