51863-4

The 51863-4 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 Circular configuration incorporates fail-safe design principles. The redundant contact system ensures continuous operation even with partial connection failure.Precision-machined for 6 Stud interfaces, this terminal features anti-galling properties. The specialized surface treatment reduces friction during mating while preventing seizing.With a 0.031" (0.79mm) profile, this component achieves optimal strength-to-weight ratio. The material selection has been validated for use in high-vibration environments.The 0.250" (6.35mm) dimension includes radiused corners to prevent insulation damage. This design feature is critical for maintaining dielectric integrity in high-altitude applications.The 0.844" (21.44mm) 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 18 AWG conductors, this terminal features a graduated compression zone. The precision-engineered crimp profile ensures optimal strand capture.The Insulated system exceeds MIL-DTL-38999 requirements for flame resistance. The material formulation produces minimal toxic emissions when exposed to fire.Incorporating Insulation Restriction, this connector demonstrates exceptional EMI/RFI shielding effectiveness. The seamless design provides 360 shielding with >90dB attenuation.The Red, White Stripe identification conforms to military wiring standards. High-contrast markings remain legible after repeated cleaning and decontamination.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.
