BRE.4S.200.NAS

The BRE.4S.200.NAS by LEMO 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 Cap (Cover), Blanking, 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 4B, 4S Series Panel Mount Receptacle, the accessory demonstrates zero outgassing in ultra-high vacuum (10^-9 Torr) conditions. Materials selection follows NASA outgassing standards for space applications.The cryogenic Brass 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.Featuring Contains Strap with Ring, Dust Tight, Water Resistant, this solution provides ultra-low thermal conductivity (<0.1 W/mK) while maintaining 100Gbps data transmission. Its monolithic construction eliminates differential contraction issues in cryogenic environments.The Silver options incorporate low-emissivity coatings to minimize radiative heat transfer. Special finishes reduce infrared signature in sensitive detector applications.
