327289-4

TE Connectivity AMP Connectors's 327289-4 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 Rectangular Tongue 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.The 0.200" (5.08mm) specification balances weight savings with current-carrying capacity. This thickness is calculated to withstand vibration frequencies typical in turbine engine environments.At 4.800" (121.92mm), this terminal provides proper clearance for high-voltage avionics systems. The length includes margin for thermal contraction at high-altitude temperatures.The 1.800" (45.72mm) 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 500MCM (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.
