Product details
Designed for precision instrumentation, the D38999/24FJ4SNLC 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 Female Sockets 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 Bulkhead - Front Side Nut 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 Aluminum construction demonstrates 80% lighter weight than comparable brass housings. The material's CTE matches PCB substrates to prevent thermal stress failures.Electroless Nickel 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.Shielded effectiveness exceeds MIL-STD-461G RE102 requirements up to 18GHz. The seamless shell design eliminates RF leakage paths common in multi-part housings.
