Frequently Asked Questions
What position count and pitch does the SFM-123-L2-F-D-A-K provide for board-to-board connections?
The SFM-123-L2-F-D-A-K provides 46 positions in a dual-row configuration at 0.050 inch (1.27 mm) pitch, with 23 positions per row. This compact pitch allows designers to route 46 signal lines in a much smaller PCB area than standard 0.100 inch pitch alternatives, ideal for space-constrained high-density applications.
How does the L2 designation in the SFM-123-L2-F-D-A-K part number affect the connector design?
The L2 designation in the SFM-123-L2-F-D-A-K indicates a specific lead length or lead style variant within the SFM series. This affects the standoff height and solder tail dimensions relative to the PCB surface, allowing designers to select the appropriate version for their 0.050 inch pitch 46-position surface mount application based on board stack height requirements.
In which high-reliability industries is the SFM-123-L2-F-D-A-K socket strip commonly specified?
The SFM-123-L2-F-D-A-K is commonly specified in defense electronics, aerospace avionics, and medical device applications where connectors must withstand extended mating cycles, vibration, and temperature extremes. The 46-position 0.050 inch pitch dual-row design meets the density requirements of these sectors, and Samtec's high-reliability construction ensures stable contact resistance over thousands of mating cycles.
