Product details
TE Connectivity AMP Connectors's 638831-5 revolutionizes Coaxial Connectors (RF) connectivity for automotive radar and ADAS systems. This ruggedized solution combines automotive-grade reliability with RF performance that meets 77GHz automotive radar requirements.The SMB, Fakra interface features minimized flange dimensions for space-constrained installations. The low-profile design reduces aerodynamic drag in vehicle-mounted applications.Utilizing Jack, Male Pin configuration, the connector achieves <-25dB PIM performance at 2x43dBm. The multi-point contact design eliminates non-linear junctions.Crimp technology provides vibration-resistant connections per LV 214-2016. The friction-locked contacts maintain <10m resistance under 50G vibration.With Crimp methodology, the connector achieves <1 ground path resistance up to 100GHz. The segmented shielding design prevents ground loops in array antennas.The 50Ohm matched transition features tapered dielectric compensation for ultra-wideband performance. Measured group delay variation is <5ps across 76-81GHz band.Designed for Free Hanging (In-Line) installation, the connector withstands 1000 thermal cycles (-40 C to +125 C). The material CTE is matched to automotive-grade PCBs.Validated with RG-174, 316 cables, the connector maintains amplitude stability within 0.2dB under hood temperatures. The high-temperature dielectric withstands 150 C continuous operation.The Locking Ramp mechanism provides tool-less installation meeting VW 60330 standards. The positive engagement system provides audible mating confirmation.Characterized at 3 GHz, the connector exhibits insertion loss <0.3dB at 77GHz. The surface finish minimizes conductor loss at millimeter-wave frequencies.With 1 automotive-qualified channels, the connector supports multi-sensor fusion architectures. Each port features integrated moisture barriers.Advanced Code E include radar-absorbing materials for reduced antenna coupling. The connector is qualified per AEC-Q200 for automotive safety systems.The Green, Leaf housing material meets BMW GS 94004 chemical resistance requirements. The laser-markable surface permits permanent identification marking.The Brass formulation provides stress relaxation resistance at 150 C. Material properties are verified per USCAR-2 vibration standards.
