MV18-8R/LK

3M's MV18-8R/LK pioneers new possibilities in Terminals - Ring Connectors, specifically developed for underwater robotics and subsea applications. This pressure-tolerant terminal connector delivers reliable performance at extreme depths while resisting marine corrosion.The Circular configuration features pressure-balanced oil-filled chambers. This innovative design maintains constant contact force up to 10,000psi external pressure.Engineered for 8 Stud interfaces, this terminal employs hyperbolic contact geometry. The unique shape provides 40% higher normal force than conventional designs at depth.With 0.030" (0.76mm) pressure hull construction, this component withstands 20:1 safety factor at rated depth. Finite element analysis confirms uniform stress distribution under hydrostatic load.The 0.310" (7.87mm) dimension incorporates hydrodynamic flow channels. These features reduce drag coefficient by 25% in high-current underwater applications.The 0.930" (23.62mm) measurement includes double O-ring seals. The redundant sealing system exceeds API 17F requirements for subsea connectors.The Free Hanging (In-Line) design enables ROV-operable connections. The torque-limited coupling mechanism prevents over-tightening during remote operations.Utilizing Crimp technology, this connector creates pressure-resistant joints. The metal-to-metal seal maintains integrity through 5,000 pressure cycles from 1atm to 500bar.Compatible with 18-22 AWG conductors, this terminal features pressure-compensated termination. The automatic adjustment maintains constant contact pressure regardless of depth.The Insulated system resists seawater absorption. Testing shows <0.1% weight gain after 1-year immersion in 35ppt saline at 50 C.Incorporating Brazed Seam, this connector provides real-time integrity monitoring. The integrated sensors detect seal degradation before water intrusion occurs.The Red coding uses photoluminescent markers for low-light identification. The markings remain visible in turbid water conditions up to NTU 50.Fabricated from Copper, ETP, the contacts resist galvanic corrosion. The alloy selection provides <5 V/cm2 galvanic potential in seawater environments.The Tin plating prevents marine biofouling. Testing demonstrates 90% reduction in barnacle adhesion compared to standard finishes.
