What are the key features of SFM-124-L2-FM-D-LC?
- 48-position dual-row socket on 1.27 mm (0.050 inch) pitch offers high-density SMT interconnect in a compact board footprint
- Low-cost (-LC) plating option reduces per-unit connector cost while maintaining reliable electrical performance for standard mating applications
- High-reliability socket strip construction supports repeated mating cycles required by modular and field-replaceable board designs
What is SFM-124-L2-FM-D-LC used for?
The SFM-124-L2-FM-D-LC is suited for 48-signal board-to-board mating on compact embedded modules, sensor interface daughtercards, and low-power IoT gateway expansion boards. Its 1.27 mm pitch SMT design minimizes PCB footprint and eliminates through-hole drilling, making it cost-effective for medium-volume production runs using standard reflow soldering processes.

Frequently Asked Questions
What pitch and position count does the SFM-124-L2-FM-D-LC offer and how compact is its PCB footprint?
The SFM-124-L2-FM-D-LC provides 48 positions on a 1.27 mm (0.050 inch) pitch in a dual-row surface mount configuration. At this pitch, the dual-row body spans approximately 30.48 mm in length for 24 positions per row, delivering a space-efficient footprint roughly half the size of an equivalent 2.54 mm pitch connector with the same pin count.
What does the -LC suffix on the SFM-124-L2-FM-D-LC indicate and when should engineers choose it over a standard gold finish?
The -LC suffix denotes a low-cost contact plating option, which reduces per-unit connector price compared to the standard heavy gold finish. Engineers should choose the -LC version for designs requiring fewer than 100 mating cycles, such as factory-programmed modules or single-board computers where connectors are mated once or only a handful of times, rather than in high-cycle test fixtures.
Which embedded computing or sensor designs benefit from a 48-position 1.27 mm pitch dual-row socket?
Compact embedded SBCs, 48-channel analog sensor interface cards, and industrial IoT expansion modules operating at 3.3 V or 1.8 V I/O logic levels benefit from this 48-position 1.27 mm pitch socket. The dual-row layout concentrates all 48 signals into a narrow 2-row by 24-column grid, supporting high routing density on 4-layer or 6-layer PCBs with limited board area.
