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.
