Key Features
- 32-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch for compact high-density board-to-board connections
- High-reliability contact design rated for thousands of mating cycles, suitable for field-serviceable daughter card applications
- Surface-mount termination enabling automated reflow soldering and low-profile PCB assembly with minimal board clearance requirements
Applications
The SFM-116-L2-STL-D is used in high-density board-to-board mating applications such as FPGA daughter card sockets, memory module test fixtures, and modular industrial controller daughter boards. Its 32-position dual-row surface-mount configuration enables efficient signal routing in space-constrained enclosures. The high-reliability contact design makes it well suited for telecom line cards and embedded computing platforms requiring repeatable low-insertion-force mating.

Frequently Asked Questions
How many positions and rows does the SFM-116-L2-STL-D socket strip have?
The SFM-116-L2-STL-D is a 32-position dual-row socket strip with 0.050 inch (1.27 mm) pitch, providing 16 contacts per row and enabling high-density signal connections within a compact surface-mount footprint on PCB assemblies.
For which board-to-board applications is the SFM-116-L2-STL-D most appropriate?
This 32-position, 1.27 mm pitch SMT socket is well suited for daughter card mating in FPGA evaluation boards, signal acquisition modules, and modular industrial controllers where boards must mate reliably across thousands of insertion cycles while maintaining impedance below 30 mΩ per contact.
How does the surface-mount termination of the SFM-116-L2-STL-D simplify PCB assembly?
The SFM-116-L2-STL-D surface-mount leads are compatible with standard reflow soldering profiles up to 260°C, eliminating the need for through-hole drilling and allowing automated pick-and-place assembly, which reduces assembly cost and improves pad co-planarity to within 0.1 mm across all 32 positions.
When is SFM-116-L2-STL-D preferred over through-hole socket strips for the same pitch?
The SMT SFM-116-L2-STL-D is preferred when board thickness is below 1.6 mm, when the mated height budget is under 5 mm, or when double-sided board assembly requires placing components on both surfaces without through-hole lead protrusion interfering with the opposite-side components.
