Frequently Asked Questions
How does the 0.050" pitch of the SFM-124-L2-FM-D-A-K compare to standard 0.100" pitch connectors for high-density designs?
At 0.050" (1.27 mm) pitch, the SFM-124-L2-FM-D-A-K provides twice the pin density per linear inch compared to 0.100" (2.54 mm) pitch connectors. A 48-position dual-row layout occupies only about 0.60 inch of board length, versus 1.20 inch for an equivalent 0.100" pitch strip, enabling tighter placement on compact PCBs used in FPGA and mezzanine card designs.
What contact technology does the SFM-124-L2-FM-D-A-K use and how many mating cycles does it support?
The SFM-124-L2-FM-D-A-K uses the Samtec friction mate (FM) contact system with gold-plated contacts rated for a minimum of 200 mating cycles. The dual-row arrangement distributes normal mating forces evenly across 48 pins, reducing per-contact stress and supporting reliable signal integrity in applications with infrequent board-swap operations such as test fixtures and module upgrades.
Which mating header from SAMTEC is compatible with the SFM-124-L2-FM-D-A-K for a complete mezzanine interconnect solution?
The SFM-124-L2-FM-D-A-K mates with SAMTEC TFM or TSM series terminal strips at 0.050" pitch in a 24-position-per-row dual-row configuration. The mated pair supports signal currents up to 1 A per contact at voltages up to 125 V AC/DC, covering most digital and low-voltage analog interfaces used in FPGA mezzanine, FMC, and custom daughter-card designs.
