Frequently Asked Questions
How many contacts does the SFM-129-L2-H-D-A-P-TR have and what is its row configuration?
The SFM-129-L2-H-D-A-P-TR has 58 contacts in a dual-row surface-mount configuration with 0.050-inch (1.27 mm) pitch, providing 29 contacts per row. This arrangement suits moderate-density board-to-board interconnect applications in embedded systems and industrial controllers.
Why specify the SFM-129-L2-H-D-A-P-TR in tape-and-reel format for a high-volume production run?
The TR (tape-and-reel) suffix means the 58-pin socket strips are packaged for automated pick-and-place SMT equipment, enabling consistent placement accuracy and eliminating manual loading. This reduces per-board assembly time and error rates in medium and high-volume production environments using standard reflow soldering processes.
Can SFM-129-L2-H-D-A-P-TR be used in defense or ruggedized industrial enclosures?
Yes. The SFM series is a high-reliability connector family from Samtec rated for demanding environments including defense electronics and industrial control. The 58-position dual-row socket provides robust contact retention across the temperature cycling and vibration levels commonly specified in MIL-grade and ruggedized industrial equipment standards.
How does the L2 lead style in SFM-129-L2-H-D-A-P-TR affect PCB footprint design?
The L2 lead style on the SFM-129-L2-H-D-A-P-TR indicates a specific SMT lead geometry that adds a longer solder tail compared to the standard configuration. This provides greater solder fillet area and improved mechanical retention strength after reflow, which is beneficial for 58-pin connectors subject to board flexure or connector mating force in service.
