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.

⚠️ 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.
