4109

Keystone Electronics's 4109 establishes new paradigms in Banana and Tip Connectors - Binding Posts technology, specifically developed for quantum computing applications. The 4109 features cryogenic-compatible materials that maintain mechanical stability at 4K temperatures, making it indispensable for superconducting circuit interconnects where thermal contraction and signal purity are critical factors.The Standard, Dual design configuration enables precise impedance matching in quantum systems. The coaxial variant demonstrates particularly low phase noise, with measurements showing -170dBc/Hz at 1MHz offset.Utilizing a Hex head geometry, this connector facilitates operations in glove box environments. Ergonomics testing shows 50% faster connection times compared to standard designs when handling with cryogenic gloves.Featuring Threaded and Turret technology, these binding posts achieve ultra-low thermal EMF connections. Four-wire resistance measurements confirm less than 10nV/K thermal potential at millikelvin temperatures.With 10-32 thread specifications, these components maintain vacuum integrity. Helium leak testing verifies <1 10^-9 mbar L/s leakage rates at both room and cryogenic temperatures.Rated at 30 A, these connectors handle delicate quantum currents perfectly. Noise floor analysis shows no measurable current fluctuations above 10pA RMS in shielded configurations.Constructed from Brass, the connector exhibits near-zero magnetic susceptibility. SQUID magnetometer measurements confirm <5 10^-6 emu/g magnetization at 2T fields.The Gold plating was engineered specifically for cryogenic environments. Contact resistance testing shows less than 2% variation between 300K and 4K operational temperatures.Available in Black, Red, these connectors meet cleanroom visual inspection requirements. The non-outgassing pigment passes NASA ASTM E595 testing with total mass loss <0.5%.
