Frequently Asked Questions
What pitch and position count does the SFM-122-L2-FM-D-A-K provide for fine-pitch PCB designs?
The SFM-122-L2-FM-D-A-K provides 44 positions in a dual-row configuration on a 1.27 mm (0.050 inch) pitch. This fine pitch allows high-density routing on compact PCBs and is compatible with SAMTEC's SFM-series mating headers at the same 0.050 inch spacing.
In which high-reliability applications is the SFM-122-L2-FM-D-A-K socket strip commonly used?
This 44-position socket strip is frequently used in aerospace electronics, military communication modules, and ruggedized embedded computing boards where a fine-pitch 1.27 mm dual-row SMT socket must withstand repeated mating cycles and vibration loads beyond what standard commercial-grade connectors tolerate.
How does the 0.050 inch pitch of SFM-122-L2-FM-D-A-K compare to 0.100 inch pitch strips for PCB area savings?
At 1.27 mm pitch, the SFM-122-L2-FM-D-A-K occupies roughly half the board length of a comparable 44-pin 2.54 mm (0.100 inch) strip. For a 44-position dual-row connector, this translates to approximately 28 mm versus 56 mm of connector length, freeing significant PCB real estate on constrained layouts.
