Product details
The 321877 from TE Connectivity AMP Connectors delivers military-grade performance in Terminals - Ring Connectors, specifically engineered for unmanned aerial vehicle systems. This lightweight terminal connector combines extreme environmental resistance with reliable power transmission for aerospace applications.The Circular design incorporates quick-disconnect safety features. The breakaway mechanism activates at 50N force to prevent cable damage during snag events.Precision-machined for 1/2 Stud interfaces, this terminal features anti-vibration locking. Testing per MIL-STD-810H shows zero loosening under 15Grms random vibration.With 0.091" (2.31mm) construction, this component achieves 60% weight reduction versus standard connectors. The composite material maintains full performance at -65 C to 200 C.The 1.020" (25.91mm) dimension includes aerodynamic profiling. Computational fluid dynamics analysis confirms <0.5% drag contribution at 200 knots airspeed.The 2.112" (53.64mm) measurement enables field-repairable terminations. The modular design allows in-situ connector repair without special tools.The Free Hanging (In-Line) orientation supports 360 rotation during installation. The self-aligning feature compensates for up to 5 misalignment during mating.Employing Crimp technology, this connector creates EMI-shielded joints. The seamless RF gasket design provides 70dB shielding effectiveness up to 18GHz.Compatible with 3/0 AWG high-strand-count cables, this terminal features anti-fretting design. The contact geometry prevents micro-motion damage during thermal cycling.The Non-Insulated system resists UV degradation and fungal growth. Accelerated weathering tests equivalent to 10 years outdoor exposure show no measurable material breakdown.Incorporating Brazed Seam, Serrated Termination, this connector provides built-in moisture detection. The color-changing indicator alerts maintenance crews to water intrusion before damage occurs.Constructed from Copper, the contacts withstand lightning strikes. Testing to DO-160G Section 22 shows no damage after 200kA transient exposure.The Tin plating maintains performance in thin-air conditions. Contact resistance remains stable at altitudes exceeding 60,000 feet.
