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, rail transport and industrial applications.

High currents can be easily transmitted with the smallest possible size: Size 17, single-pole, attains 300 amps and size 21, single-pole, 500 amps with high reliability and excellent integrity. Hypertac® hyperboloid contacts produce contact resistance figures as low as 0.03mΩ, 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 connectors are designed for easy insertion and quick release (Push-to-Mate). The connectors offered in metal shells, sealed to IPx7, feature 360° EMI/RFI shielding and have a polarized design with options that ease assembly allowing simple maintenance and quick changeover.
