41890

The 41890 by Conxall/Switchcraft represents a quantum leap in Circular Connectors - Accessories for quantum computing applications. This cryogenic-ready accessory maintains signal fidelity at temperatures approaching absolute zero while preventing thermal leakage in superconducting circuits.Functioning as O-Ring, this revolutionary design exhibits less than 0.1dB insertion loss at 4K temperatures. Its non-metallic construction eliminates eddy current losses in high-field MRI environments.Optimized for MIL-E-QUAL® Plug, the accessory demonstrates zero outgassing in ultra-high vacuum (10^-9 Torr) conditions. Materials selection follows NASA outgassing standards for space applications.Engineered to 18 specifications with 0.001 tolerance, the component prevents thermal shorts in multi-stage cryocooler systems. The nanoscale surface finish minimizes heat conduction through mechanical contacts.The cryogenic Neoprene Rubber composite maintains dimensional stability across 300K to 4K thermal cycles. Material testing confirms no embrittlement after 1000 cycles between room temperature and liquid helium temperatures.The Black options incorporate low-emissivity coatings to minimize radiative heat transfer. Special finishes reduce infrared signature in sensitive detector applications.
