Connectors handle up to 750A for rugged power applications

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 0.05m that will 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.

The HBB series features a polarised design with a variety of options that ease assembly allowing simple maintenance and speedy changeover for minimal system downtime. Offered in a choice of metal or high-strength composite shells, these single-pole circular connectors are sealed to IP67 and feature 360° EMI/RFI shielding. Configurations are available in cable or panel mount versions and with straight or right angle back shells, allowing users to 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 as per MIL-DTL-5015 shell sizes 20 and 24 respectively.
