Card Edge Connector
Industrial, IT Datacom
The PSAS 68PIN Vertical SMT Connector is engineered for next-generation enterprise storage and server applications requiring PCIe 5.0 signal integrity. Designed to meet the SFF-8639 specification, this receptacle connector delivers the 32GT/s data rates demanded by modern data center architectures while maintaining backward compatibility with PCIe 4.0 and SAS 3.0 infrastructures.
CONSHARE brings two decades of precision connector manufacturing expertise to this product, backed by ISO9001:2015 certification and full RoHS compliance. Whether you're designing high-performance NVMe storage arrays, enterprise servers, or AI acceleration platforms, this connector provides the electrical performance and mechanical reliability your system demands.
This connector supports both PCIe and SAS protocols on a single interface, enabling you to connect SAS HDDs, SATA drives, or NVMe SSDs without changing the board layout. For system architects, this means:
Simplified inventory management – one connector type across multiple product lines
Design reuse – the same PCB footprint works for SAS and PCIe-based storage
Future-proofing – migrate from SAS to NVMe without a complete board respin
The vertical surface-mount design positions the connector perpendicular to the PCB, making it ideal for applications where board real estate is at a premium. Compared to right-angle alternatives, the vertical orientation:
Reduces the connector's footprint on the PCB surface
Simplifies airflow management in densely packed chassis
Enables straightforward integration with standard 2.5-inch drive form factors
With 30µ" selective gold plating on contact areas and matte tin on solder tails, this connector delivers superior corrosion resistance and consistent low contact resistance over its service life. The 50µ" nickel underplate adds an additional barrier against oxidation and ensures reliable solder joint formation.
At PCIe 5.0 data rates, signal integrity is non-negotiable. The connector's 85Ω differential impedance is specifically tuned to match the characteristic impedance of high-speed PCB traces. This impedance matching minimizes reflections and insertion loss, preserving signal fidelity across the interconnect.
What this means for you: Cleaner eye diagrams, lower bit error rates, and fewer debug cycles during system validation. Your high-speed lanes will perform as specified, not as compromised by an inadequate connector.
The connector is rated for 500 mating cycles, a critical specification for enterprise environments where drives are frequently swapped for maintenance or upgrades. The insertion and withdrawal force ranges are carefully balanced:
Controlled insertion force – prevents damage to the connector or PCB during assembly
Adequate retention force – ensures the connector stays mated under vibration and shock
The molded guide posts automatically align the plug and receptacle during mating, reducing the risk of bent pins and improving assembly yield in manufacturing.
Constructed from high-temperature thermoplastic (UL94V-0 rated) and copper alloy terminals, this connector withstands the elevated temperatures of reflow soldering processes. The housing material is also halogen-free, meeting modern environmental compliance requirements without compromising mechanical strength.
In rackmount and blade servers, this connector serves as the interface between the motherboard and front-accessible drive bays. Its vertical SMT configuration enables direct connection to 2.5-inch U.2 and U.3 drives, supporting the high-density storage configurations common in hyperscale data centers.
For all-flash arrays leveraging NVMe over PCIe, this connector provides the bandwidth necessary to saturate Gen5 drives. The 32GT/s lane rate translates to approximately 4GB/s per lane, enabling storage subsystems to deliver the low latency and high throughput that modern applications demand.
Machine learning workloads are storage-intensive, often requiring rapid access to large datasets. The PCIe 5.0 interface, supported by this connector, provides the bandwidth to feed GPU and TPU accelerators without creating a storage bottleneck.
For space-constrained embedded systems, the vertical SMT form factor and surface-mount termination simplify automated assembly while maintaining the high-speed signal integrity required for edge AI and real-time analytics applications.

Finish Code | Contact Plating | Solder Tail Plating | Best For |
|---|---|---|---|
Au30" | 30µ" Gold | Matte Tin | Enterprise servers, high-reliability applications |
Au15" | 15µ" Gold | Matte Tin | Cost-sensitive commercial applications |
The Au30" specification (featured in this product) provides enhanced corrosion protection and lower contact resistance, making it the preferred choice for mission-critical enterprise environments where reliability is paramount.
Orientation | Best Application |
|---|---|
Vertical SMT | 2.5" drive bays, mezzanine cards, space-constrained designs |
Right-Angle SMT | Edge-mounted applications, add-in cards |
This vertical SMT version is optimized for applications where the connector mounts directly to the motherboard and a drive or daughter card plugs in from above.
For optimal signal integrity at PCIe 5.0 speeds, consider the following when designing your PCB footprint:
Use PCB materials with low dielectric constant (Dk in the 3.0–3.5 range) to improve signal integrity at high frequencies
Maintain 85Ω differential impedance for high-speed differential pairs
Follow the recommended PCB layout (top view) provided in the product datasheet for pad dimensions and placement
Ensure proper solder paste stencil design to achieve consistent SMT solder joints
