HBB single pole, circular connectors combine high current handling capability with small size and exceptional performance in harsh environments. Designed for use in all types of high-power applications, the HBB series is particularly suitable for electric drives used in fighting vehicles, unmanned vehicles, avionics systems, rail transport and industrial applications.

Designed for easy mating and quick release, the connectors attain standard current ratings of 300A and 500A (750A available on request) with high reliability and excellent integrity. Hyperboloid contacts produce contact resistance figures as low as 0.05mΩ which help in reducing resistive losses. This both eases the task of thermal management and allows better power handling in a smaller space with a lower overall mass.

HBB are offered in metal or plastic shells, are sealed to IPx7, feature 360° EMI/RFI shielding and have a polarized design with options that ease assembly allowing simple maintenance and quick changeover .
