Product details
The 71781-004LF from Amphenol ICC (FCI) delivers laboratory-grade performance in D-Shaped Connectors - Centronics, specifically designed for precision measurement equipment. This low-noise connector system maintains signal integrity for sensitive analog signals down to microvolt levels, making it ideal for medical imaging and test instrumentation.Outer Shroud Contacts geometry incorporates guarded contacts that reduce leakage currents below 1pA for high-impedance measurement circuits.Available in Receptacle configurations, these connectors support 10Gbps differential signaling required in modern oscilloscope front-ends.With 40 contacts arranged in optimized pinout patterns, this series minimizes parallel crosstalk below -90dB in multi-channel acquisition systems.The 2 row staggered layout reduces mutual inductance between adjacent contacts by 60% compared to conventional designs.Through Hole options include non-magnetic variants for MRI equipment and other applications sensitive to ferromagnetic interference.Employing Solder techniques, these connectors achieve thermal EMF below 0.2 V/ C for precision DC measurement applications.As a SCA-2 implementation, this series features embedded Faraday cages that provide 100dB shielding effectiveness against RF interference.Critical Board Lock, Latch Lock include hermetic sealing options and ultra-high vacuum compatibility down to 10^-9 Torr for scientific instruments.Gold, GXT™ plating combines with special underplating to maintain contact noise below 5nV/ Hz in low-level signal paths.Precision-controlled 30.0µin (0.76µm) ensures stable contact properties through 10,000 mating cycles in automatic test equipment.
