This SAS 29P SMT female connector is a compact, high-reliability electronic connector designed for high-speed signal and low-power transmission in servers, storage systems and industrial equipment. With a 1.27mm pitch and full SMT PCB mounting, it supports dense routing on multilayer boards and is suitable for automated reflow assembly.
The contact system uses phosphor bronze C5191-H terminals with a multi-layer plating structure: 50µ" nickel underplate for corrosion resistance, 30µ" gold on selected contact areas to ensure stable low contact resistance for high-speed data lines, and 80µ" matte tin on the solder area to provide strong, reliable solder joints to PCB pads. Plated brass positioning pegs help align the connector accurately during placement and improve mechanical retention on the board.
Electrically, the connector is rated at 1.5A @ 40VAC, with contact resistance ≤30mΩ, insulation resistance ≥1000MΩ and a withstand voltage of 500VAC per minute. Mechanically, it offers defined mating and unmating forces, and up to 500 mating cycles on the backplane side according to EIA 364-09, while a 48-hour gold-area salt-spray test verifies its resistance to harsh environments.
Thanks to its SMT structure, 30U" gold-plated terminals and halogen-free RoHS 2.0 compliant materials, this SAS 29-pin female connector is an ideal choice for customized wire and cable assemblies, PCB interconnects and high-density designs in server, automotive and power-electronic transmission applications.

- Communication & Networking Systems – For routers, switches, base stations and other networking equipment that need compact PCB connectors and reliable high-speed transmission.
- Industrial & Automation Electronics – Applied in industrial PCs, PLCs, motion controllers, data loggers and test instruments as PCB-to-wire or cable connectors.
- Automotive & New Energy Applications – Used in in-vehicle data recorders, infotainment units, EV chargers and energy-storage systems for signal and low-power transmission.
- Custom Wire Harness & Cable Assemblies – Suitable for OEM/ODM projects that require connector customization for PCB, wire and cable layouts in electrical and electronic devices.
⚠️ 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.
