2mm HM is the industry’s most successful backplane connector system with a strong history. It is adopted by many backplane y g y p y y pstandards…. Right Angle Female Receptacle ( Socket ) Vertical Male
The UHM connector offers the ability yto support high-speed differential signals in 2mm HM systems without costly backplane and daughter card costly backplane and daughter card re-designs.
Th UHM t i hi ld d HM The UHM connector is a shielded HM socket, designed to be intermateable and footprint compatible to HM sockets with superior impedance control and crosstalk reduction.
