Connector systems specified for embedded applications
Samtec's rugged 0.635mm pitch QMS/QFS series, or Q2, has been designed to meet industry recognised standards for embedded applications including PCI/104-Express, StackableUSB, and SUMIT. Samtec has designed Q2 connector strips with a 15.24mm stack height for top and bottom board stacking.
The PCI/104-Express standard specifies Samtec's Q2 QMS/QFS series connectors in a three bank (156pin) orientation (ASP-129637-03/ASP-129646-03) for module stacking, while the StackableUSB and SUMIT standards specify the QMS/QFS Series system in a one bank (52pin) orientation (ASP-129637-01/ASP-129646-01).
Both configurations employ Samtec's precision machined standoffs with a 15.24mm stack height (SO-1524-03-01-02-L) to meet each standard. According to Samtec, the standoffs also limit the impact of tolerance stack up issues in stackable embedded applications.
