Product details
Designed for precision instrumentation, the D38999/20KJ4AN from Amphenol Aerospace Operations sets new benchmarks in Circular Connectors - Housings performance. This ultra-reliable connector combines military-grade durability with precision signal transmission characteristics, making it ideal for laboratory equipment and measurement systems requiring nanosecond-level timing accuracy.The Receptacle Housing architecture supports impedance-controlled transmission lines with <1% variation. Time-domain reflectometry measurements show consistent 50 impedance across all contacts.Configured for For Male Pins applications, the contact plating maintains <2m resistance after 10,000 mating cycles. The noble metal plating prevents fretting corrosion in micro-motion scenarios.With 56 configuration options, the connector accommodates high-density signal routing. The patented contact arrangement reduces near-end crosstalk by 18dB at 6GHz.Compatible with 25-4 inserts, allowing customized contact arrangements. The floating insert design compensates for 1.5mm panel misalignment.Conforming to J specifications, the housing interfaces with standard circular connector accessories. The flanged design provides 360 shielding continuity.Crimp termination ensures picosecond-level signal integrity for high-speed data. The controlled impedance contacts maintain <3% reflection coefficient to 12GHz.Accommodating 16 (8), 20 (48) contacts, the design supports 100Gbps differential signaling. The elliptical contact geometry reduces skew to <1ps/inch.The Panel Mount design features integrated anti-rotation pins for precise alignment. Thermal finite element analysis confirms <0.1mm deflection at 125 C operating temperature.The Flange configuration enables hermetic sealing to 10^-9 atm-cc/s leak rate. The metal-to-metal seal withstands 5000 thermal cycles from -65 C to +175 C.Threaded mechanism provides consistent 12-15 in-lb engagement torque without lubrication. The self-cleaning threads resist contamination in foundry environments.Featuring N (Normal) polarization, the connector prevents damage from incorrect mating attempts. The tactile detent force measures 5N 0.5N for consistent operator feedback.The Stainless Steel construction demonstrates 80% lighter weight than comparable brass housings. The material's CTE matches PCB substrates to prevent thermal stress failures.Passivated surface treatment provides <0.05 contact resistance between mated shells. The coating withstands 500 hours salt spray per ASTM B117.The Silver coding system enables quick visual identification in rack-mounted systems. The UV-stable pigments maintain color fidelity for 10+ years outdoor exposure.Rated Environment Resistant, the connector survives 30-minute immersion at 1m depth. The hydrophobic seals repel oils and cutting fluids in CNC machine environments.The Firewall Usage include integrated transient voltage suppression up to 600W peak pulse. The gas-tight seals maintain performance at 0.01Torr vacuum conditions.Shielded effectiveness exceeds MIL-STD-461G RE102 requirements up to 18GHz. The seamless shell design eliminates RF leakage paths common in multi-part housings.
