Subminiature D Type UHV Ribbon Cables – Connector to Cable

UHV Cable Assemblies

Connector to cable UHV ribbon cables are fitted with PEEK subminiature D connectors at one end and non terminated, Kapton^® insulated ribbon cable at the other. The female cable connectors mate directly onto the vacuum side of subminiature D feedthroughs  or with the male in-vacuum cable connectors. The ribbon cable is made with Kapton^® insulated 28AWG silver plated copper conductors, stranded 7 x 0.127mm. The cables are woven with a PEEK monofilament with a nominal diameter of 0.2mm.
Contact to cable UHV ribbon cables do not include PEEK connectors.

Stated electrical ratings are maximum test values. Feedthroughs are intended for instrumentation applications carrying low level signal voltages and currents.

For proper heat dissipation a maximum of 20% of the pins on a feedthrough may carry the maximum current at any one time.

Features:
• 7 x 0.127mm (28AWG) wires woven into a ribbon cable.
• PEEK monofilament weave.
• UHV compatible.
• Custom lengths available.
