SAS 29P Female PCB Connector with Positioning Peg, Ni/Au/Sn Plated Terminals, 1.27mm Pitch Electronic Terminal Connector for Customization in Server & Automotive Applications

The SAS 29P Mixed Angle Female Connector with Positioning Peg is a specialized electronic signal and power connector designed for SAS-based server, storage and industrial systems. It features a dummy 29-pin layout where the 11th pin is intentionally left vacant, and a mixed-angle structure with 15 pins bent down 90° and 7 pins straight 180°, allowing highly flexible routing for PCB and wire-cable assemblies.

Terminals are produced from phosphor bronze C5191-H (t = 0.25mm) and finished with a robust three-layer plating system:

• Nickel ≥50u" under the gold area and nickel ≥25u" under the tin area for corrosion resistance;

• 15u" minimum gold on the contact area to ensure low contact resistance and stable high-speed electrical signal performance;

• 80u" minimum tin on the solder & crimp area for strong, reliable solder joints to copper wires.

The connector uses glass-filled LCP housing and base (black, UL94-V0, Halogen-Free), delivering excellent mechanical strength, dimensional stability and heat resistance for demanding electrical and electronic environments.

Electrical performance includes a rated current of 1.5A @ 40VAC, contact resistance ≤30mΩ, insulation resistance ≥1000MΩ, and withstand voltage 500VAC/minute. Mechanically, the connector supports mating force up to 50N, unmating force at least 20N, single pin retention ≥0.8kgf, and 25 mating cycles at 200 cycles/hour, ensuring long-term stability.

A positioning peg and housing bump (top boss) provide accurate alignment and additional mechanical locking, making this connector ideal for customized PCB, wire and cable configurations in space-constrained systems.

Key Features

• Phosphor bronze C5191-H terminals provide strong spring force and durability under vibration and repeated mating
• LCP G/F UL94-V0 HF housing ensures high mechanical strength and heat resistance in harsh electronic environments
• Positioning peg and top boss improve assembly accuracy and mechanical retention in PCB and cable assemblies
• Defined mating/unmating forces and single-pin retention ≥0.8kgf guarantee secure connections during handling and operation
• Suitable for electrical / electronic signal and power transmission, especially in server, storage and automotive applications where customization is required

⚙️ Applications

• This SAS 29P female connector is suitable for a variety of electrical / electronic uses:
• Server & Data Center Equipment
  • Dummy or special-coding connectors on SAS backplanes
  • PCB connectors for controller boards, test boards and interposers in data-center servers
• Storage & Communication Systems
  • HDD/SSD interface boards where specific pins must be isolated or used for mechanical keying
  • Communication equipment using SAS-style high-speed signal connectors
• Automotive & Industrial Electronics
  • Data logging units, industrial PCs and testers that need customized SAS-type connector footprints
  • Wiring harness modules where mixed-angle pins simplify cable routing and stress relief
• Custom PCB & Wire Cable Assemblies
  • OEM / ODM projects requiring connector-level customization (dummy pins, special angles, position coding)
  • Electrical signal and power connectors in compact devices where standard SAS connectors cannot meet layout constraints

⚠️ Notes

• Design the PCB pad and hole layout according to the 1.27mm pitch and mixed-angle structure (15P 90° + 7P 180°) to avoid mechanical interference.

• When soldering wires to the tin-plated areas, follow an appropriate soldering profile to ensure full wetting and reliable joints while protecting the LCP housing.

• Keep gold-plated contact areas clean; avoid touching the terminals with bare hands to prevent contamination and oxidation.

• Make full use of the positioning peg and housing bump for accurate alignment in fixtures, housings or over-molded shells, reducing stress on terminals.

• Do not exceed the specified mating/unmating forces and mating cycles to maintain terminal elasticity and connector life.

• Store connectors in dry, anti-static packaging, and handle them in ESD-protected areas when assembling into sensitive electronic equipment.

• Operate the connector only within the rated temperature range (–20°C to +85°C) and electrical ratings to ensure long-term reliability.
