What are the key features of SFM-109-T2-F-D-LC?
- 18-position dual-row surface-mount socket strip at 0.050" (1.27 mm) pitch for high-density board-to-board interconnects
- High-reliability Tiger Claw contact design delivers consistent mating force and long cycle life for frequent insertion applications
- Low-clearance (-LC) profile minimizes vertical stack height between mated boards, saving space in compact multi-board assemblies
What is SFM-109-T2-F-D-LC used for?
SFM-109-T2-F-D-LC is used in high-density board-to-board stacking applications for embedded computing, FPGA daughtercards, and communications modules where a 0.050" pitch dual-row socket is required. The low-clearance surface-mount design enables tight board stacking in compact instrument enclosures and industrial control hardware, while the high-reliability contacts support repeated mating and demating during field maintenance.

Frequently Asked Questions
What pitch and row count does SFM-109-T2-F-D-LC use, and which mating header series is it designed to accept?
SFM-109-T2-F-D-LC uses a 0.050" (1.27 mm) pitch dual-row layout with 18 total positions to mate with SAMTEC TFC or TSM series 0.050" pitch headers. The 1.27 mm pitch allows 18 signals to route in half the board space of equivalent 0.100" pitch connectors, making it ideal for FPGAs, mezzanine cards, and daughtercards where PCB real estate below 20 mm² is critical.
How does the low-clearance (-LC) designation affect the stacking height between two PCBs mated with SFM-109-T2-F-D-LC?
The -LC (low clearance) variant of SFM-109-T2-F-D-LC reduces the board-to-board mating height compared to standard-profile socket strips, typically achieving inter-board gaps of 2 mm or less. This compact vertical stack height is essential in multi-board assemblies such as embedded SBCs, plug-in mezzanine modules, and compact instrument chassis where total enclosure depth is constrained to under 10 mm.
In a design requiring frequent board removal during testing, how many mating cycles can SFM-109-T2-F-D-LC reliably handle?
SFM-109-T2-F-D-LC is rated as a high-reliability socket strip, typically supporting 100 or more mating cycles without degraded contact resistance at 0.050" pitch. This cycle life exceeds standard low-cost socket strips by a factor of 2 to 3, making it suitable for test fixture daughtercards, prototype development boards, and field-replaceable module interfaces where repeated insertion of 18-position assemblies occurs over the product lifecycle.
