New connectors for high power applications

04 September 2008

Now available in the UK from Aerco are Hypertac’s new HBB connectors that are rated up to 750A for use in high power applications. Providing easy mating and quick release with over 2,000 mating cycles and combining high current handling capability with small size and high levels of environmental performance, the HBB range is particularly suitable for electric drives used in fighting vehicles, weapons, avionics, rail transport and automotive and medical equipment.

These high performance connectors use Hypertac’s hyperboloid contact technology to provide standard current ratings of 300A and 500A while versions capable of over 750A are available on request. The hyperboloid contacts produce contact resistance figures as low as 0.05mW, thus cutting resistive losses. This simplifies the task of thermal management and allows better power handling in a much smaller size.

Supplied in a choice of metal or high-strength composite shells, these single-pole circular connectors are sealed to IP67 and provide 360° EMI/RFI shielding. Configurations are available in cable or panel mount versions with straight or right angle backshells.

Rated up to 1000Vdc, the HBB series can accept cable sizes of up to 70mm² for 300A versions and 120mm² for 500A versions. Receptacles are available with sizes conforming to MIL-DTL-5015, while metal versions offer a variety of plating options including zinc/cobalt, cadmium and electroless nickel.
