Phoenix Contact's 1840557 redefines Terminal Blocks - Panel Mount technology for quantum computing infrastructure. Its cryogenically-optimized design enables reliable interconnects in superconducting qubit arrays while maintaining ultra-low thermal loads in dilution refrigerator environments.The Header, Male Pins employs niobium-titanium alloy contacts that transition superconducting below 9K. This property eliminates joule heating in quantum processor I/O connections, critical for maintaining qubit coherence times.Designed for milliKelvin operation, the Bolt/Screw Clamp - Wire Entry Parallel to Panel options feature Kapton-insulated phosphor bronze springs with <10 N contact force. This delicate pressure prevents damage to fragile Josephson junction arrays while ensuring reliable connections.With 1.451" (36.86mm) options available, researchers can minimize parasitic capacitance in qubit control lines. The 3mm variant reduces crosstalk to <0.1% between adjacent qubits in 50GHz multiplexed readout systems.Compatible with 0.039 ~ 0.197" (1.0 ~ 5.0mm) specifications from 0.25mm to 3mm, the mounts adapt to both thin silicon substrates and thick copper mounting plates. The strain-free attachment prevents stress-induced frequency shifts in flux-tunable qubits.The 2 hexagonal close-packing matches surface code lattice geometries. This arrangement supports fault-tolerant quantum error correction architectures with nearest-neighbor connectivity requirements.The Screw Mount - Front Flange incorporates amorphous metal alloys to minimize magnetic flux trapping. This prevents quasiparticle generation that could decohere transmon qubits in superconducting quantum processors.Precision 0.300" (7.62mm) spacing maintains 50 impedance in coplanar waveguide feeds. The ultra-low-loss Rogers 4350B dielectric minimizes microwave attenuation in multi-qubit control and measurement systems.Rated for 600 V operation, the terminals withstand 5kV electrostatic discharges without generating Cooper pair-breaking phonons. This protection is crucial for maintaining quantum state integrity during cooldown cycles.The 35 A capacity supports persistent currents up to 10mA in superconducting loops. The niobium contacts maintain zero resistance up to their critical field strength of 200mT in fluxonium qubit applications.Supporting 10-30 AWG ranges, these terminals handle both 36AWG superconducting wiring and heavier cryocooler power leads. The bimetallic interface prevents thermal shorts while maintaining electrical continuity from 300K to 10mK stages.The Green coding uses non-fluorescent markers to avoid stray photons in dark matter detection experiments. The pigments maintain visibility under red darkroom lighting without introducing optical noise.Featuring Threaded Mating Lock, these connectors implement RF filtering for qubit control lines. The integrated -filters suppress noise above 12GHz while maintaining <0.1dB insertion loss in the 4-8GHz sweet spot for transmon qubits.The 1 single-layer design minimizes quasiparticle generation from nonequilibrium phonons. This architecture reduces dielectric loss tangents to <10^-6 in 3D superconducting quantum circuit assemblies.
