Frequently Asked Questions
What pitch and position count does the SFM-143-02-SM-D-A-K offer for high-density designs?
The SFM-143-02-SM-D-A-K features a 0.050" (1.27 mm) pitch with 86 total positions in a dual-row arrangement of 43 contacts per row, making it one of Samtec's fine-pitch high-density socket strips ideal for space-constrained PCB layouts.
In which applications does the SFM-143-02-SM-D-A-K's high-reliability socket design provide the most benefit?
The high-reliability socket contacts in the SFM-143-02-SM-D-A-K are best suited for FPGA mezzanine cards, rugged military electronics, and aerospace instrumentation modules where 86 signal connections must maintain low contact resistance below 20 mΩ through thousands of mating cycles and wide temperature swings from -55°C to +125°C.
How does the 0.050" pitch of SFM-143-02-SM-D-A-K compare to 0.100" pitch connectors when board space is limited?
At 0.050" (1.27 mm) pitch versus a standard 0.100" (2.54 mm) pitch, the SFM-143-02-SM-D-A-K reduces the connector row length by approximately half while maintaining 86 positions, allowing designers to fit twice the signal density within the same PCB footprint — critical for compact embedded computing and high-layer-count backplane designs.
