Infinite Electronics’ new line of USB 2.0 and 3.0 double stack adapter couplers and cables allow users to double the number of USB ports in their rack, panel or box, but without taking up more space. They also bring faster data transmission from USB 2.0 to match cutting-edge gear. Two USB-A connector combinations are available: one with two female jacks to two male plugs, or two female to two female. The ECF-style panel mounts fit most racks and panel cutouts. The adapter cable has a chrome-plated, shielded and grounded ABS housing, and 30 micro-inch gold-plated contacts that ensure reliable connection even after repeated mating cycles. The adapter comes in chrome plated, shielded or unshielded housing types, depending on whether the user prefers to ground the connector shell to their rack, panel or box. Seven length options range from 1 foot to 10 feet.
