- Gold-plated contacts provide low contact resistance and reliable mating performance over extended use cycles
- L2 lead style with surface mount termination ensures compatibility with automated reflow soldering processes
- High-reliability construction suits demanding industrial, telecom, and defense board-to-board interconnect applications
Applications
The SFM-132-L2-SM-D-A-K is well-suited for high-density board-to-board signal interconnect applications in industrial control systems, telecommunications line cards, and server backplanes requiring 64 signal positions. Its 0.050" pitch dual-row SMT design allows designers to route a large number of signals across mated PCBs while maintaining a small footprint. Defense electronics and test equipment manufacturers also select this connector for its proven reliability and compatibility with automated assembly processes.

Frequently Asked Questions
How many positions and rows does the SFM-132-L2-SM-D-A-K provide, and what pitch does it use?
The SFM-132-L2-SM-D-A-K is a 64-position connector arranged in 2 rows of 32 positions each, with a 0.050" (1.27 mm) pitch between contacts. This high-density dual-row layout enables compact PCB routing of 64 signal or power lines in board-to-board interconnect applications.
What does the L2 lead style mean for the SFM-132-L2-SM-D-A-K during PCB assembly?
The L2 designation on the SFM-132-L2-SM-D-A-K specifies a surface mount lead style with extended leads that improve solder joint inspectability during automated reflow soldering at standard peak temperatures of 260°C, making it easier to verify solder quality on high-pin-count SMT connectors.
Which applications benefit most from using the SFM-132-L2-SM-D-A-K over a through-hole connector?
Applications that require both high channel count (64 positions) and double-sided PCB populations benefit most: server mezzanine cards, telecom line cards, and industrial I/O expansion modules gain space savings and allow components on the back side of the board, advantages not achievable with through-hole 0.050" pitch alternatives.
What contact plating specification does SAMTEC apply to the SFM-132-L2-SM-D-A-K?
SAMTEC specifies gold-over-nickel contact plating—typically 30 µin (0.76 µm) gold—on the SFM-132-L2-SM-D-A-K, providing stable, low contact resistance across the 64 positions and ensuring consistent electrical performance even after repeated mating cycles in high-vibration environments.
How does the SFM-132 compare to the SFM-117 variant in terms of position count?
The SFM-132-L2-SM-D-A-K provides 64 positions versus 34 positions in the SFM-117 series, both using the same 0.050" (1.27 mm) pitch dual-row SMT format. Designers needing 30 additional signal lines can upgrade from SFM-117 to SFM-132 without changing pad pitch or assembly process.
