Product details
The 1950490000 from Weidmüller represents a quantum leap in Terminal Blocks - Headers, Plugs and Sockets technology for quantum computing applications. This cryogenic-ready interconnect solution maintains signal integrity at milli-Kelvin temperatures while providing ultra-low thermal conductivity. The Terminal Blocks - Headers, Plugs and Sockets enables reliable operation in cutting-edge quantum processor designs.Featuring Plug, Female Sockets construction, this component achieves unprecedented thermal performance at cryogenic temperatures. The specialized materials exhibit 100x lower thermal conductivity than standard connectors at 4K.Available in 20 positions, the design supports scalable qubit architectures. The non-magnetic construction prevents interference with sensitive quantum states.With 20 positions per level, the layout minimizes parasitic capacitance between control lines. This arrangement is critical for maintaining qubit coherence times.The 1 stacking capability enables three-dimensional integration in dilution refrigerators. The ultra-compact design maximizes valuable cryostat space.The 0.200" (5.08mm) pitch spacing prevents cross-talk between adjacent microwave control lines. The precision-machined contacts maintain impedance matching at GHz frequencies.270° entry geometry accommodates superconducting cabling. The strain-free termination prevents microphonic effects in sensitive measurements.Utilizing Screw - Clamping Yoke (Tension Sleeve) termination, the system ensures stable connections during thermal cycling. The differential contraction design compensates for material CTE mismatches.The Free Hanging (In-Line) mounting prevents thermal shorts in cryogenic systems. The G10 isolation standoffs reduce heat leak to milliwatt levels.Meeting 23A standards for quantum applications, the design handles picosecond pulse transmission. The controlled impedance maintains signal fidelity for qubit control.The 400 V certification includes testing for microwave leakage. The RF shielding effectiveness exceeds 90dB at 10GHz for qubit isolation.Rated for 20 A at 4K, the contacts utilize superconducting alloys. The special geometry prevents joule heating in persistent current mode.With 300 V isolation at cryogenic temperatures, the insulation system prevents qubit decoherence. The ultra-pure dielectrics exhibit negligible dielectric loss.Compatible with 12-30 AWG superconducting wires, the termination maintains critical current density. The gold-plated interfaces prevent oxidation in ultra-high vacuum.The Orange housing uses specialized low-outgassing materials for vacuum environments. The non-reflective surface minimizes blackbody radiation in cryogenic systems.Operating across -50°C ~ 100°C range, from 300K to 10mK, the materials maintain mechanical stability. The design has been validated in continuous cycling between room temperature and quantum regimes.Tin plating provides optimal performance at cryogenic temperatures. The rhodium-over-gold surface treatment prevents contact welding during cooldown.The Mating Flange, Retention Latches (Non-Wire Side) include integrated thermal anchoring points. These enable proper heat sinking of cables while maintaining electrical isolation in dilution refrigerators.
