Product details
The 031-2743-1 from Amphenol RF 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 BNC, Triaxial 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, Male Pin architecture, the connector exhibits <1pA leakage current in vacuum. The molecular barrier coating prevents outgassing contamination of sensitive optics.Solder technology ensures stable contact resistance despite atomic oxygen exposure. The gold-iridium alloy contacts withstand >10,000 thermal cycles in LEO conditions.The Clamp system provides >100dB EMI shielding against solar flare events. The multi-foil design meets MIL-STD-188-164 requirements for spacecraft bonding.Precision-controlled Non-Constant 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 Essex 21-738 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 Bayonet Lock mechanism provides positive engagement with <5N m torque in zero-G. The captive hardware meets NASA-STD-8739.4 requirements.Characterized at 500 MHz, 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 Silver anodization provides <5% solar absorptance in AM0 conditions. The optical properties remain stable under UV and proton radiation.Exceeding Weatherproof requirements, the connector survives meteoroid impacts per ECSS-Q-ST-70-04. The redundant sealing system maintains vacuum integrity after mechanical shock.The Brass formulation resists cold welding in vacuum with <10mg contact force. The beryllium-copper alloy maintains spring properties at cryogenic temperatures.
