Frequently Asked Questions
How many contact positions and what pitch does the SFM-128-L2-FM-D support?
The SFM-128-L2-FM-D provides 56 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch. This high-density layout allows engineers to route up to 56 signal lines in a compact surface-mount footprint, making it ideal for space-constrained PCB designs requiring reliable high pin-count interconnects.
Which SAMTEC mating headers are compatible with the SFM-128-L2-FM-D?
The SFM-128-L2-FM-D is designed to mate with SAMTEC's SFM-series pin headers that share the same 0.050" (1.27 mm) pitch and dual-row 56-position pattern. Using matched SAMTEC header and socket pairs ensures controlled impedance, reduced crosstalk, and consistent insertion force across the full 56-pin interface, which is critical in signal-integrity-sensitive applications.
Is the SFM-128-L2-FM-D suitable for high-cycle industrial applications?
Yes, the SFM-128-L2-FM-D is built to SAMTEC's high-reliability standards, supporting repeated mating cycles demanded by industrial test fixtures and automated equipment. The socket strip's surface mount termination withstands standard SMT reflow temperatures, and the gold-plated contacts maintain low contact resistance across hundreds of insertions, making it suitable for burn-in boards and instrumentation where durability over many cycles is mandatory.
