Key Features
- 50-position dual-row layout on 0.050-inch (1.27 mm) pitch for high-density board-to-board mating
- Tiger Eye contact technology with 30 µin gold mating finish for superior reliability and low insertion force
- Surface-mount termination with matte tin (Sn) over nickel (Ni) barrier for robust solder joint integrity
- Compact SMT footprint: 1.265 inch body length, 0.19 inch depth, designed for space-constrained PCB layouts
Applications
The SFM-125-02-S-D-P-TR is suited for high-density board-to-board interconnects in industrial computing, communications, and test-and-measurement systems where 50-position dual-row, 0.050-inch pitch sockets are required. Its Tiger Eye contact system and gold mating surface make it a preferred choice for backplane and mezzanine card assemblies that demand reliable, low-resistance mating cycles. Surface-mount placement enables automated PCB assembly in compact electronic modules.

Frequently Asked Questions
What is the contact pitch and row configuration of the SFM-125-02-S-D-P-TR?
The SFM-125-02-S-D-P-TR uses a 0.050-inch (1.27 mm) pitch dual-row layout with 50 total positions (25 per row), making it suitable for high-density board-to-board applications where space on a PCB is limited.
Which PCB assembly processes are compatible with the SFM-125-02-S-D-P-TR surface-mount package?
This connector uses a surface-mount termination style with matte tin (Sn) over nickel (Ni) barrier plating, making it fully compatible with standard SMT reflow soldering processes at typical peak reflow temperatures of 260°C, enabling automated pick-and-place assembly.
How does the Tiger Eye contact technology in the SFM-125-02-S-D-P-TR improve mating reliability over standard sockets?
Tiger Eye contacts provide a wiping dual-beam design that maintains consistent normal force across 50 positions, combined with 30 µin gold mating finish to reduce contact resistance and support hundreds of mating cycles without degradation in high-vibration industrial or telecom environments.
What are the body dimensions of the SFM-125-02-S-D-P-TR for PCB layout planning?
The connector body measures 1.265 inches in length, 0.145 inches in breadth, and 0.19 inches in depth, giving designers precise keep-out dimensions for routing signal traces and placing adjacent components on a densely populated PCB.
