Key Features
- 34-position dual-row surface-mount socket at ultra-fine 0.050" (1.27 mm) pitch for high-density board-to-board signal routing in compact PCB assemblies
- High-reliability construction with press-fit (P) retention provides mechanical stability during reflow and field operation in vibration-prone environments
- Dual-row (D) layout distributes 34 contacts across two rows, reducing connector body length compared to single-row alternatives at the same pin count
Applications
The SFM-117-L2-FM-D-A-P is designed for high-reliability board-to-board interconnects in aerospace, defense, and industrial automation equipment requiring 34 signals at 0.050" pitch with anti-vibration press-fit retention. Its dual-row SMT configuration supports dense PCB layouts in backplane systems, FPGA mezzanine cards, and ruggedized embedded computing platforms where signal integrity and mechanical durability are critical.

Frequently Asked Questions
What is the pitch and contact count of the SFM-117-L2-FM-D-A-P and how does it benefit compact PCB designs?
The SFM-117-L2-FM-D-A-P provides 34 positions in a dual-row configuration at a 0.050" (1.27 mm) pitch. Compared to standard 0.100" pitch alternatives, the 0.050" pitch reduces the connector footprint by approximately 50%, enabling significantly denser PCB layouts for applications requiring 34 signal connections in space-constrained boards.
How does the press-fit (P) designation on SFM-117-L2-FM-D-A-P improve assembly reliability?
The press-fit feature mechanically locks the SFM-117-L2-FM-D-A-P into the PCB before and during soldering, preventing the 34-position dual-row strip from shifting during reflow. This is particularly important for fine-pitch 0.050" pitch connectors where even sub-millimeter misalignment can cause bridging or opens across the dual-row contact pattern.
In what high-reliability applications is the SFM-117-L2-FM-D-A-P typically used?
This 34-position, 0.050" pitch dual-row SMT socket strip is commonly used in FPGA mezzanine card (FMC) interconnects, ruggedized industrial control backplanes, aerospace avionics modules, and defense electronics where high-reliability 34-pin board-to-board connections must withstand vibration, shock, and thermal cycling over extended service lifetimes.
How does SFM-117-L2-FM-D-A-P compare to SAMTEC single-row SFM connectors for the same 34-pin count?
The dual-row (D) SFM-117-L2-FM-D-A-P at 0.050" pitch distributes 34 contacts across 2 rows, resulting in a connector body length of approximately 17 positions per row (0.85"), versus a single-row 34-position SFM connector at approximately 1.65" long. The dual-row version is significantly shorter, which is advantageous when board edge space is limited along one axis.
