Product details
The 1757821-3 by TE Connectivity Aerospace, Defense and Marine sets new standards in D-Sub, D-Shaped Connectors - Housings for particle accelerator systems, optimized for ultra-high vacuum and radiation environments. This specialized D-Sub connector enables precise beam control and diagnostics in synchrotrons and linear accelerators.Implementing D-Sub architecture, the connector achieves 90% reduction in outgassing compared to conventional UHV connectors while maintaining RF shielding effectiveness.The Plug for Male Contacts design features all-metal seals that maintain <10^-11 Torr L/s leak rates in bakeable ultra-high vacuum systems.With 25 available circuits, the configuration supports beam position monitors, corrector magnets, and RF cavity controls in single compact interface.Precision 2 row arrangement prevents beam-induced heating effects at average beam currents up to 1A.The 3 (DB, B) incorporates beam dump shielding that attenuates prompt radiation by >10^6 for personnel safety.Special Signal contacts employ radiation-resistant alloys that maintain <5m contact resistance after 10^9 rad(Si) exposure.Optimized for Free Hanging (In-Line) installation, the connector features alignment pins accurate to 5 m for precise beam instrumentation positioning.The Housing/Shell (Unthreaded) includes ConFlat compatible flanges that integrate directly with standard UHV chamber configurations.Utilizing Steel, Yellow Chromate Plated Zinc, the housing demonstrates <0.001% magnetic permeability to prevent beam steering effects.Precision 20µin (0.51µm) plating provides stable secondary emission characteristics for electron cloud mitigation.
