Product details
The 277149-8 from TE Connectivity AMP Connectors redefines excellence in Terminals - Ring Connectors, specifically engineered for aerospace and defense applications. This mil-spec terminal connector delivers unmatched performance in extreme environments through advanced materials and precision manufacturing processes.The Flat Sided, Tubular (Battery Lugs) configuration incorporates fail-safe design principles. The redundant contact system ensures continuous operation even with partial connection failure.Precision-machined for 1/4 Stud interfaces, this terminal features anti-galling properties. The specialized surface treatment reduces friction during mating while preventing seizing.With a 0.082" (2.08mm) profile, this component achieves optimal strength-to-weight ratio. The material selection has been validated for use in high-vibration environments.The 0.627" (15.92mm) dimension includes radiused corners to prevent insulation damage. This design feature is critical for maintaining dielectric integrity in high-altitude applications.The 2.000" (50.80mm) measurement provides sufficient leverage for proper torque application. The calibrated deformation zone indicates correct installation visually.The Free Hanging (In-Line) orientation enables high-density packaging in avionics systems. The low-profile design meets ARINC 600 spacing requirements.Employing Crimp technology, this connector creates permanent, high-integrity joints. The process produces intermetallic bonds that withstand extreme thermal cycling.Compatible with 4 AWG (Al), 6 AWG (Cu) conductors, this terminal features a graduated compression zone. The precision-engineered crimp profile ensures optimal strand capture.The Non-Insulated system exceeds MIL-DTL-38999 requirements for flame resistance. The material formulation produces minimal toxic emissions when exposed to fire.Constructed from Copper, the contacts exhibit excellent resistance to stress corrosion cracking. This property is critical for long-term reliability in harsh environments.The Tin plating provides superior performance in low-pressure environments. Testing confirms stable contact resistance at altitudes exceeding 50,000 feet.
