52558-4

The 52558-4 from TE Connectivity Aerospace, Defense and Marine 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 D-Shaped configuration incorporates fail-safe design principles. The redundant contact system ensures continuous operation even with partial connection failure.Precision-machined for 1/2 Stud interfaces, this terminal features anti-galling properties. The specialized surface treatment reduces friction during mating while preventing seizing.With a 0.136" (3.45mm) profile, this component achieves optimal strength-to-weight ratio. The material selection has been validated for use in high-vibration environments.The 1.535" (38.98mm) dimension includes radiused corners to prevent insulation damage. This design feature is critical for maintaining dielectric integrity in high-altitude applications.The 2.671" (67.84mm) 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 300-350MCM (kcmil) 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.Incorporating Brazed Seam, this connector demonstrates exceptional EMI/RFI shielding effectiveness. The seamless design provides 360 shielding with >90dB attenuation.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.
