SAS 29P SMT Female Connector 1.27mm Pitch, Type 45 Version with 30U" Gold-Plated

This SAS 29P Type 45 SMT female connector is designed for high-density electronic signal and low-power transmission in servers, storage arrays, communication equipment and industrial control systems. With a 1.27mm pitch and full SMT PCB mounting, it supports compact layouts and automated reflow assembly for high-volume production.

The 29-pin layout provides separate high-speed differential pairs and power/ground pins, making it ideal as a SAS backplane connector for HDD/SSD and other storage devices. Terminals are stamped from a high-strength phosphor bronze alloy and finished with a multilayer plating system: a nickel underlayer for corrosion protection and 30U" gold flash on the contact area to ensure low, stable contact resistance and clean high-speed signal transmission. Tin-plated solder areas deliver strong, reliable joints to the PCB pads.

The connector is rated at 1.5A @ 40VAC, with contact resistance ≤30mΩ, insulation resistance ≥1000MΩ and a withstand voltage of 500VAC per minute. Mechanical performance is controlled with a maximum mating force of 25N, minimum unmating force of 5N, and up to 500 mating cycles on the backplane side in accordance with EIA 364-09. A 48-hour salt-spray test on the gold area verifies good resistance to harsh environments.

Using halogen-free, RoHS 2.0 compliant LCP housing material, this SAS 29-pin SMT female connector is a robust choice for customized PCB, wire and cable designs in server, automotive, industrial and power-electronic transmission applications.

⚙️ Applications

• Server & Data Center Equipment – Used as SAS / SATA electronic signal and power connectors on HDD/SSD backplanes, RAID cards, JBOD/NAS and 1U/2U server boards.
• 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.
