The Hi/Mate™ Series are miniature insertable/removable high voltage contact assemblies for use in MIL-C-38999 Series I, III and IV off-the-shelf connectors having a 12 gauge, rear release, contact retention cavity.

Hi/Mate™ expands the capability of MIL-C-38999 Series I, III and IV connectors, by adapting them to carry 13.5 kVDC from sea level to airborne applications up to 70,000 feet altitude over a temperature range of -55 °C to 125 °C.

Hi/Mate™ contact assemblies are insertable into four standard shell sizes and eight insert arrangements in accordance with MILSTD-1560. These contact assemblies are, in actuality, independent high voltage connectors, and do not rely upon the dielectric properties of the MIL-C-38999 insert. This fact makes the Hi/Mate™ ideally suited to be combined in inserts with fiber optic, co-axial or low voltage pins. The insert is merely a holder for the Hi/Mate™ contact and Advanced Interface Seal™.

The Advanced Interface Seal™ was patented by Teledyne Reynolds and has been highly successful in numerous connectors designed for use in theharshest of environments from sea level to Deep Space.
