2MM Hard  Metric Backplane Connector


The 3M  Ultra Hard Metric (UHM) Socket Connector is the industry’s first fully-shielded
2 mm hard metric (HM) connector designed for more than 7 Gbps backplane  performance with a high signal density when used with unshielded industry  standard 2 mm HM backplane headers. The UHM socket is designed to be  intermateable to 2 mm HM IEC 61076-4-101 headers and is fully compatible with 2  mm HM PCB footprints.
The UHM socket connector’s unique  design enables backplane designs using widely available standard 2 mm HM  connectors to support greater than 7 Gbps performance, high signal integrity  applications. Examples of backplane designs using 2 mm HM connectors are PICMG  CompactPCI® 3U and 6U and VITA VME 64x. Using the UHM socket connector, standard  CompactPCI and VME 64x systems can, for the first time, support high density of  multi-gigabit high speed serial IO protocols such as SAS, SATA, Rapid IO, PCI  Express and Gigabit Ethernet.

 The UHM socket connector uses unique patented  “virtual coaxial box” shielding technology to provide a tightly controlled  impedance fully-shielded differential pair (100 ohm) or single-ended (50 ohm),  low crosstalk transmission path through the connector. Full shielding forms a  virtual coaxial box around signal contacts individually and/or in pairs. This  dramatically reduces crosstalk as compared to a standard unshielded 2 mm HM  socket.

 The UHM socket connector is  available in 5-row (A, B, CL, CR, AB) and 8-row (D, E, DE, FL, FR) form factors  allowing a very high signal density – 101 signals per linear inch for the 8-row  and 63 signals per linear inch for the 5-row. The unique construction of the UHM  socket connector supports 100 ohm differential pairs in rows or columns. Running  differential pairs in rows eliminates row-to-row skew.
