La série HBB Smiths Connectors est une gamme de connecteurs circulaires de puissance unipolaire conçue pour les applications militaires et industrielles. Les connecteurs HBB sont étanches (IP67) et bénéficent d'un mécanisme de verrouillage autoguidé Disponible en versions plastique et métal renforcé.

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 0.05mΩwhich 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 polarised design with options that ease assembly allowing simple maintenance and quick changeover.
