Product details
The D38999/20TH55JN-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 Receptacle 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 55 contact options, the design supports complex satellite payload architectures. The optimized contact arrangement minimizes signal skew to <1ps/inch.Compatible with 23-55 inserts, allowing customized signal routing. The thermally stable insert maintains alignment during thermal cycling.Conforming to H 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 Panel Mount installation survives 100G shock loads during launch. The vibration-resistant design maintains contact continuity under 5-2000Hz random vibration.The Flange design enables hermetic sealing to 10^-11 atm-cc/s leak rate. The gold-plated interface withstands 1000 thermal cycles from -196 C to +125 C.Threaded mechanism provides consistent engagement torque in zero-gravity. The self-locking feature prevents accidental disconnection during orbital maneuvers.Featuring N (Normal) polarization, the connector prevents mismating in identical-looking harnesses. The tactile coding system is operable with space gloves.The Aluminum construction provides excellent strength-to-weight ratio for space applications. The material meets NASA outgassing requirements with <0.1% TML.Durmalon™ surface treatment maintains <0.05 contact resistance in vacuum. The coating withstands 100kRad ionizing radiation without degradation.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.Shielded effectiveness exceeds 120dB at 10GHz for sensitive payload protection. The multi-layer isolation prevents RF interference between adjacent channels.
