PowerWize Blind-Mate Interface (BMI) Connectors

Power efficiency is critical to cost and safety management in power-intensive applications such as power transmission systems in datacenters, base stations, battery management, and inverters. PowerWize BMI connectors incorporate Molex’s proven COEUR socket which has multiple contact beams to create a large contact surface at the contact interface, resulting in very low contact resistance. The voltage drop across the contact interface is very low with minimal heat generation.

Dense electronic packaging often requires designs where subassemblies are mated without visual guidance, such as drawer-style applications. PowerWize BMI connectors are designed for blind-mating situations. Guide rails engage before the electrical components to help ensure gross alignment and the panel-mount housing flanges allow ±2.0 mm of radial self-alignment to mitigate tolerance stack-up issues.

High-power wire-to-board/busbar interconnects can be attached to a wide range of substrates and crimped to a wide range of wire gauges. PowerWize BMI screw-mount headers can attach to either printed circuit boards or busbars and PowerWize BMI solder tail headers attach to printed circuit boards. PowerWize BMI crimp machined contacts cover a wide range and will accept 1/0 AWG, 2 AWG, 4 AWG, 6 AWG, 8 AWG, or 10 AWG wires.
