Product details
The D38999/26KD18JB-LC from Amphenol Aerospace Operations represents the pinnacle of Circular Connectors - Housings technology for satellite communications. Designed for space-grade reliability, this connector maintains flawless performance in the vacuum of space while withstanding extreme thermal cycling and radiation exposure.As a Plug Housing solution, it features hermetic sealing for space vacuum applications. Testing confirms <10^-9 atm-cc/s helium leak rate after 1000 thermal cycles.Configured for For Female Sockets implementations, the contact system prevents outgassing contamination in vacuum environments. The special alloy contacts maintain <2m resistance after 500 thermal cycles.With 18 contact options, the design supports complex satellite payload architectures. The optimized contact arrangement minimizes signal skew to <1ps/inch.Compatible with 15-18 inserts, allowing customized signal routing. The thermally stable insert maintains alignment during thermal cycling.Conforming to D specifications, the housing interfaces with standard space-qualified accessories. The reinforced design withstands 100G acceleration during launch.Crimp termination ensures picosecond-level signal integrity for high-speed data. The controlled impedance contacts maintain <1.5 VSWR to 40GHz.Designed for 20 contacts, the current capacity remains stable in vacuum. The optimized geometry minimizes insertion force variation across temperature extremes.The Free Hanging (In-Line) installation survives 100G shock loads during launch. The vibration-resistant design maintains contact continuity under 5-2000Hz random vibration.Threaded mechanism provides consistent engagement torque in zero-gravity. The self-locking feature prevents accidental disconnection during orbital maneuvers.Featuring B polarization, the connector prevents mismating in identical-looking harnesses. The tactile coding system is operable with space gloves.The Stainless Steel construction provides excellent strength-to-weight ratio for space applications. The material meets NASA outgassing requirements with <0.1% TML.Passivated surface treatment maintains <0.05 contact resistance in vacuum. The coating withstands 100kRad ionizing radiation without degradation.The Silver identification system remains visible after prolonged UV exposure in space. The non-outgassing pigments are compatible with ultra-high vacuum.Rated Environment Resistant, the design maintains 10^-12 Torr vacuum integrity. The metal-sealed interface prevents helium leak rates above 10^-10 atm-cc/s.Integrated Coupling Nut, Firewall Usage, Self Locking include radiation-hardened components for GEO satellite applications. The design withstands 100kRad total ionizing dose without performance degradation.Shielded effectiveness exceeds 120dB at 10GHz for sensitive payload protection. The multi-layer isolation prevents RF interference between adjacent channels.
