Compact HBB connectors handle 300, 500 or 750A currents
Hypertac's new HBB connectors combine high current handling capability with small size and exceptional environmental performance for demanding power systems applications. The HBB range is suitable for use in all types of high-power applications. This is particularly applicable to electric drives used in fighting vehicles, weapons systems, ground-based and airborne avionics systems, rail transport and the automotive and medical sectors.
Designed for easy mating and quick release, the devices use Hypertac's hyperboloid contact technology to attain standard current ratings of 300A and 500A (plus 750A available on request) with high reliability and excellent integrity. Hyperboloid contacts produce contact resistance figures as low as 0.05mOhm that helps in reducing resistive losses. This both eases the task of thermal management and permits better power handling in a smaller space with a lower overall mass.
The HBB series connectors feature a polarised design with a variety of options that ease assembly, simplify maintenance and minimise system downtime. Offered with either metal or high-strength composite shells, these single-pole circular connectors are sealed to IP67 and feature 360-degree EMI/RFI shielding. Configurations are available in cable- or panel-mount versions and with straight or right-angle backshells, so users can choose the most appropriate variants to simplify their cable management architecture and therefore further increase reliability and reduce the likelihood of interconnection errors.
Rated for use at up to 1000V DC, 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 can be specified with a variety of plating options including zinc/cobalt, cadmium and electroless nickel.
Flange mounting sizes for 300A and 500A connectors are as per MIL-DTL-5015 shell sizes 20 and 24 respectively.
