SAS 3.0 29Pin Female PCB Connector, 1.27mm Pitch Mixed SMT + TH Pin Terminal

This SAS 3.0 29Pin female connector is designed for high-speed electronic signal and low-power transmission in compact server, storage and industrial systems. With a 1.27mm pitch and a mixed 7SMT + 7SMT + 15TH structure, it combines the high-density advantages of SMT pads with the mechanical strength of through-hole pins, providing a reliable PCB connector solution for both signal and power lines.

Terminals are stamped from phosphor bronze C5191-H and finished with a multilayer plating system: 50µ" nickel underplate for corrosion resistance, 30µ" gold on the contact area to ensure stable low-resistance signal paths, and 80µ" tin on the solder area for strong solder joints to the PCB. The peg is made from brass C2680-H with Ni/Sn plating to improve positioning and mechanical retention. The housing and cap use glass-filled LCP, black, UL94-V0, providing excellent heat resistance, dimensional stability and flame retardancy.

Electrically, the connector is rated at 1.5A @ 40VAC, with contact resistance ≤30mΩ, insulation resistance ≥1000MΩ, and 500VAC dielectric withstand. Mechanically, it supports up to 500 mating cycles on the backplane side and 25 cycles on the cable side under EIA 364-09, with controlled mating and unmating forces to protect the PCB and solder joints. This makes it an ideal connector choice for customized PCB, wire and cable layouts in servers, communication equipment, automotive electronics and other high-reliability 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.
