The 10039851-101LF is a right-angle header connector with 4-wall construction designed for AirMax VS® backplane and midplane applications. This connector features 8 columns with 24 differential pairs and a 2mm column pitch, enabling flexible board layout and reduced PCB routing complexity. The connector uses innovative edge-coupling and air dielectric technology to deliver low insertion loss and crosstalk performance, with contact resistance of =35mO initial and =10mO increase after environmental testing. It supports a current rating of 0.5A per contact at =30°C rise above ambient and offers durability of 200 mating cycles with mating force of 0.45N max. per contact. The shieldless open pin field design provides ultimate flexibility for telecom, networking, server, and storage applications while reducing connector cost, weight, and system complexity.
