Key Features
- 18-position dual-row configuration with 0.050" (1.27 mm) pitch for compact, high-density SMT board interconnects
- Short tail length (STL) contact design minimizes PCB standoff height for low-profile and space-constrained assemblies
- High-reliability construction tested for demanding industrial and aerospace connector performance requirements
- Surface mount termination compatible with automated pick-and-place and standard solder reflow assembly processes
- Compatible with SAMTEC TSM and TMS series male headers sharing the 0.050" pitch for complete mated pair solutions
Applications
The SFM-109-T2-STL-D-A-K is well-suited for space-constrained PCB interconnects in portable instrumentation, industrial sensor modules, and small form factor embedded computing boards requiring an 18-position dual-row connector at 1.27 mm pitch. The short tail length (STL) variant is particularly advantageous in low-profile PCB stack designs and thin module carriers where minimizing overall board height is critical.

Frequently Asked Questions
What does STL mean in the SFM-109-T2-STL-D-A-K part number, and how does it affect PCB mounting?
STL stands for Short Tail Length, indicating that the contact tails are shorter than standard, which reduces the overall standoff height of the connector after SMT soldering. This allows thinner PCB stacks and is valuable in low-profile embedded modules or portable devices where keeping board-to-board separation under a critical height—such as under 5 mm—is required.
How many positions and rows does the SFM-109-T2-STL-D-A-K connector provide for a board-to-board link?
The SFM-109-T2-STL-D-A-K provides 18 positions arranged in a dual-row format (2 rows of 9 contacts) with a 0.050" (1.27 mm) pitch. This 18-position count is suited for moderate I/O density applications in industrial sensors, medical monitoring modules, and small embedded computing boards requiring a reliable SMT socket interface.
Which mating SAMTEC male headers pair with the SFM-109-T2-STL-D-A-K for a complete connector assembly?
The SFM-109-T2-STL-D-A-K is designed to mate with SAMTEC TSM and TMS series male pin headers in a dual-row 18-position, 0.050" (1.27 mm) pitch configuration. These male headers complete the board-to-board interconnect pair and are available in various stacking heights and termination styles to meet specific application clearance requirements.
Can the SFM-109-T2-STL-D-A-K be used in industrial automation equipment that experiences mechanical vibration?
Yes. The SFM-109-T2-STL-D-A-K is rated for high-reliability applications and its dual-row 18-position design with 0.050" (1.27 mm) pitch contacts provides redundant contact points that help maintain electrical continuity under vibration. The SMT termination also creates a mechanically secure solder bond compared to press-fit alternatives, making it appropriate for industrial automation and motion control environments.
