High-Reliability SAS 29P 180° IDC Female PCB Connector, Ni/Au/Sn Plated Terminals | Electrical Wire Cable Connector Customization for Server & Power Applications

The SAS 29P IDC Female Connector 1.27mm Pitch 180° Straight is a high-density electronic signal connector designed for SAS-based server, storage and industrial systems. It uses an IDC (insulation-displacement) termination to quickly connect flat cables or discrete wires without stripping, greatly improving assembly efficiency for mass production of wire harnesses and cable assemblies.

Each terminal is made of phosphor bronze C5191-H and plated with 50U" nickel, 15U" gold on the contact area, and 80U" tin on the IDC area, ensuring low contact resistance, excellent corrosion resistance and reliable mechanical retention. The housing and base are LCP G/F, black, UL94-V0, providing high strength and heat resistance.

With 1.5A @ 40VAC, ≤30mΩ contact resistance, ≥1000MΩ insulation resistance and 500VAC dielectric withstand, this connector delivers stable performance for high-speed signal and low-power transmission in compact equipment.

• 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.
