Product details
The MU18-4R/SK from 3M 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 4 Stud interfaces, this terminal features anti-vibration locking. Testing per MIL-STD-810H shows zero loosening under 15Grms random vibration.With 0.030" (0.76mm) construction, this component achieves 60% weight reduction versus standard connectors. The composite material maintains full performance at -65 C to 200 C.The 0.250" (6.35mm) dimension includes aerodynamic profiling. Computational fluid dynamics analysis confirms <0.5% drag contribution at 200 knots airspeed.The 0.600" (15.24mm) 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 18-22 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.Constructed from Copper, ETP, 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.
