These high reliability (HI-REL) assemblies, which are intermateable with various LGH™ interfaces, are rated from 10 to 25 kVDC and will operate at altitudes up to 70,000 ft. over a temperature range of -55°C to 125°C. In comparison to the C Series, this series has improved temperature range exposure at altitude operation due to incorporation of annular sealing rings on the plug insulator.

HI-REL plugs are offered in kit form when customers find it necessary to fabricate cable assemblies. Customers should use silicone rubber or silicone coated FEP cable of a diameter matching the rear insulator hole. Fluorosilicone rubber insulators are available for applications where Coolanol® or other fluids that cause silicone rubber to swell may exist.

Plastic bodies are used in the HI-REL plug design to captivate the coupling nut and prevent tearing of silicone insulators from overtorque during mating.

This family of connectors have been widely used for more than 25 years in Military/Aerospace applications. Typical applications are:

• Electronic Countermeasure Systems (ECM)
• TWT connections
• Lasers
• Airborne high voltage power supplies
