Since the HSHM backplane connectors are based on IEC 61076-4-101 – the industry standard for 2mm hard metric connectors - these fully shielded socket connectors are footprint compatible with unshielded HM connectors on a typical single board computer. This means the unshielded HM socket can be replaced with a press-fit shielded connector with relative ease making the 3M™ MetPak™ HSHM connector the high-speed solution for challenging electrical performance requirements in 5-row hard metric backplanes.
