40149

3M's 40149 delivers aerospace-grade performance in Terminals - Rectangular Connectors for next-generation avionics systems. This lightweight connector combines exceptional vibration resistance with minimal signal loss, critical for flight control and navigation electronics. The materials are selected for optimal performance across extreme altitude and temperature conditions encountered in commercial and military aircraft.The Lug, Grounding design ensures reliable signal transmission despite extreme G-forces and vibration. The contact geometry is optimized to prevent micro-arcing in low-pressure environments.Available in 1/2 Stud configurations, this terminal meets diverse avionics power distribution requirements. The contacts feature special alloys to prevent cold welding in vacuum conditions.With Two Stud Holes architecture, this connector provides positive locking for critical flight systems. The design includes secondary retention features that meet FAA redundancy requirements.At 6.000" (152.40mm), this terminal provides proper clearance for high-voltage avionics systems. The length includes margin for thermal contraction at high-altitude temperatures.The 1.250" (31.75mm) dimension allows for efficient heat dissipation in confined avionics bays. This design prevents thermal buildup in continuous operation scenarios.The Free Hanging (In-Line) configuration enables rapid maintenance access in aircraft electrical systems. This design allows for tool-less servicing in confined cockpit spaces.Employing Crimp, Barrel technology, this connector maintains performance despite rapid pressure changes. The gas-tight connections prevent moisture ingress during descent cycles.Supporting 250MCM (kcmil) conductors, this terminal accommodates both heavy power feeds and delicate sensor wiring. The design prevents conductor fatigue from constant aircraft vibration.The Non-Insulated system provides arc tracking resistance for high-altitude electrical systems. The material maintains dielectric strength despite rapid decompression events.The Red coding follows aerospace standards for quick identification in low-light cockpit conditions. The markings remain visible after years of UV exposure at high altitudes.
