The Hi/MateD™ Series of high voltage insertable/removable contact assemblies are rated at 13.5 kVDC and can be fitted into a Subminiature-D (Sub-D) 8 gauge insert cavity. The assemblies are ideal for airborne applications up to 70,000 feet altitude over a temperature range of -55 °C to 125 °C. Hi/MateDis fully compatible with signal lines, co-axial, fiber optic and power contacts in the same Sub-D connector. These contact assemblies are independent high voltage connectors, and do not rely upon the dielectric properties of the Sub-D insert.

Complete cable assemblies with Hi/MateD™ high voltage contact assemblies installed into Positronic CBD Series Subminiature-D connectors, are available from Teledyne Reynolds as fully tested units.
