Product details
Amphenol ICC (Commercial Products)'s L777HRD78P delivers breakthrough D-Sub, D-Shaped Connectors - Housings performance for fusion energy research, engineered to withstand extreme plasma environments. This high-voltage D-Sub connector enables reliable diagnostics and control signal transmission in tokamak and stellarator applications.Featuring D-Sub, High Density design, the connector achieves 80% better resistance to X-ray induced conductivity compared to standard high-voltage connectors.The Plug for Male Contacts configuration employs graded insulation that prevents partial discharge up to 40kV in 10^-5 Torr vacuum conditions.With 78 available channels, the design supports multi-channel diagnostics including Langmuir probes, interferometers, and bolometers.Special 4 row spacing prevents flashover at 50kV potentials in hydrogen plasma environments.The 5 (DD, D) High Density incorporates boron nitride insulating layers that withstand neutron fluxes up to 10^14 n/cm s.Utilizing Signal contacts with refractory metal cores that maintain mechanical properties at 1000 C bakeout temperatures.Designed for Free Hanging (In-Line) installation, the connector features ceramic standoffs that provide 100kV/mm dielectric strength in ultra-high vacuum.The Housing/Shell (Unthreaded) includes copper gaskets that maintain vacuum integrity through 1000 thermal cycles from room temperature to 400 C.Incorporating Grounding Indents, the design implements optical isolation barriers that prevent ground loops in sensitive plasma measurement systems.Constructed with Steel, Tin Plated, the housing demonstrates exceptional resistance to hydrogen embrittlement and tritium permeation.Precision 100µin (2.54µm) plating ensures stable secondary electron emission characteristics (<1.0 yield) in strong magnetic fields.
