POWER CONNECTORS

BusMate®

Power Busbar Connector System

BusMate® provides an efficient, high-density power interface to connect one bus to another in power steering motors, traction drives and power conversion, inversion, and distribution systems. As a highly reliable and assembly-friendly solution, BusMate® enables compact and robust power assembly designs with its small footprint and large ampacity-to-size ratio.

SMALL
HIGH-POWER DENSITY
INNOVATION

BusMate® can support robust power densities, from 40 to 60 Amp interfaces up to 60 to 80 Amps. Its flexibility enables cost-effective creation and assembly of a variety of connector arrays to handle different mating configurations such as board-to-blade, board-to-board, and blade-to-blade scenarios.
