Frequently Asked Questions
How does SFM-136-T2-L-D-A-P-TR achieve 72 circuits within the constraints of a 0.050 inch pitch SMT footprint?
By using a dual-row arrangement at 0.050 inch (1.27 mm) pitch, the SFM-136-T2-L-D-A-P-TR places 36 contacts per row across two parallel rows, yielding 72 total positions in a body length of approximately 1.800 inches (36 positions × 0.050 inch pitch). This nearly halves the board edge length required versus a 0.100 inch pitch single-row equivalent for the same 72-circuit count.
What role does the polarization feature play in preventing assembly errors on a 72-position socket strip?
With 72 positions at 0.050 inch pitch, manual alignment verification is impractical without mechanical assistance. The polarization key on SFM-136-T2-L-D-A-P-TR physically blocks 180-degree reversal mating, ensuring the mated connector pair aligns correctly on the first insertion. This is critical in FPGA carrier and backplane designs where a miswired 72-circuit bus could damage components powered through the connector.
When designing a high-density FPGA I/O expansion board, what advantages does SFM-136-T2-L-D-A-P-TR offer over two separate 36-position connectors?
A single SFM-136-T2-L-D-A-P-TR replaces two 36-position connectors, reducing board area by eliminating the inter-connector gap and saving at least one connector landing zone. Electrical continuity across all 72 positions is guaranteed with a single mating operation, reducing assembly steps. The unified 0.050 inch pitch footprint also simplifies PCB routing by keeping all 72 I/O signals within a single connector outline.
