SAS 29Pin SMT Female PCB Connector 1.27mm Pitch, 30U" Gold Electronic Signal Terminal Connector for Server, Automotive & Power Transmission Wire Cable Customization

This SAS 29P SMT female connector is a compact, high-reliability electronic connector designed for high-speed signal and low-power transmission in modern servers, storage devices and industrial equipment. With a 1.27mm pitch and fully SMT PCB layout, it supports dense routing on multilayer boards while keeping assembly easy for automated reflow processes.

The contact system uses phosphor bronze C5191 terminals with a robust plating stack: 50µ" nickel underplate for corrosion resistance, 30µ" gold on the contact area to maintain low and stable contact resistance, and 80µ" matte tin on the solder area to ensure strong, reliable solder joints to the PCB pads. Two plated brass positioning pegs help align the connector accurately during SMT placement.

Electrically, the connector is rated at 1.5A @ 40VAC, with contact resistance ≤30mΩ, insulation resistance ≥1000MΩ, and a withstand voltage of 500VAC/minute. Mechanically, it offers controlled mating and unmating forces and up to 500 mating cycles on the backplane side according to EIA 364-09, while a 48-hour salt-spray test on the gold area demonstrates excellent resistance to harsh environments.

Thanks to its SMT structure, gold-plated terminals and halogen-free RoHS 2.0 compliant materials, this SAS 29-pin female connector is ideal for customized wire and cable assemblies, PCB interconnects and high-density designs in server, storage, automotive and other power-electronic applications.

⚠️ Notes

• Make sure the working voltage, current and temperature of your design stay within the connector’s rated values, with proper safety margin.
• Design PCB pads, holes and mechanical space according to the drawing and pitch, and avoid bending or twisting stress on the connector after soldering or assembly.
• Select appropriate wire gauge, insulation and cable structure based on current load, signal speed and bending requirements for both power and signal terminals.
• For IDC / crimp types, use matched tooling and press-force to ensure full insulation displacement; for solder types, follow a controlled soldering profile to avoid overheating the LCP housing.
• Insert and pull out the connector along the mating direction, avoid pulling on the cable itself, and do not exceed the specified mating/unmating force or durability cycles.
• Keep gold-plated contact areas clean and dry, avoid touching them with bare fingers, and store products in dry anti-static packaging before assembly.
