What are the key features of SFM-109-02-H-D-LC-TR?
- 18-position dual-row 1.27mm pitch socket strip with H high-mount profile providing generous clearance for taller components on mated boards
- LC low contact force mating design reduces insertion force by up to 50% compared to standard contacts, preventing PCB flexure during assembly
- Gold-plated contacts on tape-and-reel packaging delivering consistent 1A per contact reliability across -55°C to +125°C operating range
What is SFM-109-02-H-D-LC-TR used for?
The SFM-109-02-H-D-LC-TR is well suited for high-density board-to-board stacking in embedded processor modules, wireless communication shields, and sensor expansion boards requiring 18 signal connections. Its high-mount H profile provides extra clearance above the lower PCB, accommodating taller passive components or heat sinks between the mated boards. The low contact force design reduces mechanical stress during repeated mating cycles, extending connector service life in field-serviceable industrial and laboratory equipment.

Frequently Asked Questions
What does the H (high-mount) profile mean for the SFM-109-02-H-D-LC-TR stack height?
The H designation on the SFM-109-02-H-D-LC-TR specifies a high-mount profile that results in a mated board-to-board separation of approximately 7mm to 11mm, depending on the complementary header height selected. This extra clearance accommodates taller components such as electrolytic capacitors or RF shields between the two stacked PCBs, making it suitable for complex multi-board assemblies in industrial control and communications hardware.
For an 18-signal sensor board, how does the LC low contact force feature of the SFM-109-02-H-D-LC-TR benefit repeated mating?
The LC (low contact force) design reduces the insertion force required to mate the 18-position connector by approximately 50% compared to standard contact styles. This lower force prevents PCB warping and solder joint stress during assembly, and makes manual mating feasible on thin, flexible substrates. In test fixtures where sensor boards may be inserted and removed 100 or more times, the reduced force extends the connector's mechanical lifespan while maintaining contact resistance below 30 milliohms.
How does the SFM-109-02-H-D-LC-TR compare to a 2x9 0.1-inch pitch connector for the same 18-position application?
The SFM-109-02-H-D-LC-TR at 1.27mm pitch occupies roughly half the PCB footprint length compared to a 2.54mm pitch 2x9 header, reducing connector board area from about 45mm to approximately 22mm for an 18-position dual-row layout. The higher density is advantageous in space-constrained embedded modules, though the finer pitch requires more precise SMT placement with pick-and-place accuracy of at least ±0.1mm to avoid bridging.
