The SAS 29P Solder-Type Female Cable Connector 180° with Positioning
Peg & Top Boss is a robust electronic signal and power connector designed for SAS-based server, storage and industrial
applications. With a 1.27mm pitch housing and 29 female pins, it enables compact, high-density wire and cable assemblies between backplanes, test fixtures or dummy ports and
controller boards.
Each terminal is made from phosphor bronze C5191-H (t = 0.25mm) and receives a three-layer plating system:
50u" minimum nickel over the entire terminal 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 tail for strong solder joints to copper wires in cable harnesses.
The glass-filled LCP housing (black, UL94-V0, Halogen-Free) offers excellent mechanical strength, dimensional stability and
heat resistance, making the connector suitable for demanding
electrical and electronic equipment.
Electrically, the connector is rated at 1.5A @ 40VAC, with contact resistance ≤30mΩ, insulation resistance ≥1000MΩ, and withstand voltage 500VAC/minute. Mechanical specifications define mating and unmating forces for both backplane and cable, and single pin retention ≥0.8kgf, ensuring that terminals remain secure even under vibration and
handling.
The positioning peg and top boss help align the connector accurately in jigs, housings or
over-molded shells, simplifying assembly and improving reliability
for customized wire, cable and PCB interconnect solutions.

⚠️ Notes
- Select appropriate wire gauge and insulation according to the 1.5A @ 40VAC rating and application requirements
(signal + power).
- Use the recommended soldering process for the tin-plated tails; ensure sufficient solder wetting for low
resistance and high pull-out strength.
- Keep the gold-plated contact area clean; avoid touching terminals with bare fingers to prevent
contamination and oxidation.
- When assembling, make full use of the positioning peg and top boss to align the connector correctly in fixtures or housings, reducing
stress on the terminals and PCB.
- Do not exceed the specified mating/unmating forces for backplane and cable to maintain terminal elasticity and
connector lifetime.
- After durability testing (up to 25 cycles at 200 cycles/hour),
verify that contact resistance per pin remains ≤30mΩ and that no distortion, cracks or deformation appear.
- Store connectors in dry, anti-static packaging, and handle them in ESD-protected areas when integrating into
sensitive electronic systems.
- Operate only within the specified temperature range (–20°C to +85°C) and electrical ratings to guarantee long-term reliability.
