Product details
The 131-8404-011 from Cinch Connectivity Solutions Johnson sets new benchmarks in Coaxial Connectors (RF) performance for satellite payload systems. Designed for GEO orbit conditions, this connector maintains flawless signal integrity through 15+ years of continuous operation in the space environment.Featuring SMB, Mini configuration, the connector achieves <0.001dB/mate insertion loss variation after 500 thermal cycles. The radiation-hardened dielectric prevents total dose effects up to 100kRad.With Plug, Female Socket architecture, the connector exhibits <1pA leakage current in vacuum. The molecular barrier coating prevents outgassing contamination of sensitive optics.Crimp or Solder technology ensures stable contact resistance despite atomic oxygen exposure. The gold-iridium alloy contacts withstand >10,000 thermal cycles in LEO conditions.The Crimp system provides >100dB EMI shielding against solar flare events. The multi-foil design meets MIL-STD-188-164 requirements for spacecraft bonding.Precision-controlled 75Ohm maintains <0.5% deviation across -150 C to +125 C. The compensated dielectric design accounts for thermal expansion in vacuum.Designed for Free Hanging (In-Line) installation, the connector withstands 50G vibration during launch. The titanium housing provides >98% radiation shielding effectiveness.Qualified with RG-179DS, 187DS space-grade cables, the connector passes NASA outgassing tests with <0.1% TML. The strain relief system survives 1,000 flex cycles in thermal vacuum.The Snap-On mechanism provides positive engagement with <5N m torque in zero-G. The captive hardware meets NASA-STD-8739.4 requirements.Characterized at 2 GHz, the connector shows <0.05dB PIM in high-power RF applications. The multipaction-resistant design handles 5kW peak power at altitude.With 1 isolated channels, the connector supports redundant spacecraft systems. Each port features individual radiation-hardened ESD protection.The Gold anodization provides <5% solar absorptance in AM0 conditions. The optical properties remain stable under UV and proton radiation.The Beryllium Copper formulation resists cold welding in vacuum with <10mg contact force. The beryllium-copper alloy maintains spring properties at cryogenic temperatures.
