A low-profile object is defined as lower or slimmer than what is typical. Samtec’s new low-profile PCI Express® Gen 4 edge card connector fits the bill. It is designed to meet the industry demands for greater density and higher performance in compact electronics.
This new low-profile edge card connector (PCIE-LP Series) is PCI Express® Gen 4 compliant and supports one, four, eight and sixteen links for different bandwidth requirements. It also features Edge Rate® contacts on a 1.00 mm (.0394”) pitch for optimized signal integrity performance.
The incredibly low 8 mm profile is 3 mm less than the standard 11 mm profile connector with an identical 3.50 mm contact wipe. Ultimately this providesmore vertical space in a standard size chassis with a set form factor allowing for greater system air flow and space to route other components over the connector. The low 8 mm profile connector is ideal for applications where space is limited or dimensions are not pre-determined.
“We are excited to introduce the new PCIE-LP Series, which adds to Samtec’s already extensive and diverse edge card solutions,” said Terry Emerson, Micro Rugged Project Manager at Samtec, Inc. “This interconnect meshes high-speed signals with a smaller than industry standard form factor and enables customers to have more flexibility when designing their systems.”With PCI Express® Gen 4 compliance, this edge card connector achieves a 16 GT/s bit rate to meet the industry demands for increased bandwidth. Support of the PCI Express® protocol also ensures low latency, power savings and guaranteed transmission of the connector.
Samtec’s Edge Rate® contact system is designed to increase cycle life and minimize the effects of broadside coupling. This decreases crosstalk for superior signal integrity performance and impedance control. Rugged Edge Rate® contacts are also less prone to damage when “zippered” during unmating.
Standard PCI Express® expansion cards, 1.60 mm (.062”) thick cards and Samtec’s PCI Express® jumpers (PCIEC Series) mate with the low-profile edge card connector, making it a good alternative to the standard PCI Express® edge card. Polarization to ensure proper mating and surface mount tails are standard options; press-fit tails are in development.
