What are the key features of SFM-106-L2-SM-D-LC?
- 12-position dual-row 0.050" (1.27 mm) pitch SMT socket enabling 6 contacts per row in an ultra-compact low-current board interface
- Low-current (LC) contact rating optimized for signal-level applications requiring minimal contact resistance and high signal integrity
- High-reliability gold-plated contacts designed for repeated mating cycles in demanding industrial and instrumentation applications
- Surface-mount termination compatible with standard lead-free reflow processes for automated PCB assembly
What is SFM-106-L2-SM-D-LC used for?
The SFM-106-L2-SM-D-LC is used in signal-level board-to-board connections within precision instrumentation, medical sensors, and compact industrial modules where a 12-pin dual-row 0.050" pitch SMT socket is required at low current levels. Its high-reliability gold-plated low-current contacts maintain signal integrity across the 12-pin interface even after multiple mate-and-unmate cycles, supporting modular sensor designs and calibration equipment with removable PCB modules. The compact 0.050" pitch footprint enables dense PCB layouts in size-constrained enclosures.

Frequently Asked Questions
What does the LC (low-current) designation mean for the SFM-106-L2-SM-D-LC contact rating?
The LC designation on the SFM-106-L2-SM-D-LC indicates that the contacts are optimized for low-current signal applications, typically rated below 1 A per contact, with contact geometry and gold-plating thickness tuned to minimize contact resistance for small signal voltages at the 0.050" (1.27 mm) pitch interface. This makes the 12-position socket unsuitable as a power connector but ideal for routing digital, analog, or RF signals in precision instruments, sensor boards, and data acquisition modules where signal integrity matters more than current capacity.
How compact is the SFM-106-L2-SM-D-LC footprint compared to a 12-pin connector at 0.100" pitch?
The SFM-106-L2-SM-D-LC uses 0.050" (1.27 mm) pitch for its 12 positions arranged in 2 rows of 6, resulting in a connector body approximately 8 mm long. An equivalent 12-position connector at 0.100" (2.54 mm) pitch would require roughly 16 mm of board length for the same contact count, meaning the SFM-106-L2-SM-D-LC occupies about half the board footprint. This compact size is critical in miniaturized medical sensor modules and wearable device designs where PCB area is severely limited.
When should a designer choose the SFM-106-L2-SM-D-LC over a higher-current-rated socket strip for a 12-pin interface?
A designer should select the SFM-106-L2-SM-D-LC when all 12 contacts carry only signal-level currents typically below 1 A and the design priority is minimizing contact resistance and maximizing signal integrity at 0.050" (1.27 mm) pitch rather than handling power loads. In applications such as precision ADC reference signal routing, sensor output connections, or SPI bus interfaces between a microcontroller and a removable sensor PCB, the low-current gold contact geometry of the SFM-106-L2-SM-D-LC provides better electrical performance than a general-purpose higher-current-rated socket at the same pitch.
