Frequently Asked Questions
What pitch and row configuration does the SFM-137-02-FM-D-A use?
The SFM-137-02-FM-D-A uses a 0.050" (1.27 mm) pitch in a dual-row surface mount configuration, providing 74 positions total. This fine pitch enables high-density interconnects in space-constrained PCB applications.
Which mating connector families are compatible with the SFM-137-02-FM-D-A for board-to-board stacking?
The SFM-137-02-FM-D-A is designed to mate with SAMTEC TSM and SFM header series at 0.050" (1.27 mm) pitch. The dual-row 74-position layout supports high-density signal routing in embedded computing and telecommunications board stacking designs.
How does the SFM-137-02-FM-D-A's gold-plated contact finish affect reliability in cycling applications?
Gold-plated contacts on the SFM-137-02-FM-D-A minimize contact resistance and resist oxidation, maintaining stable connections through hundreds of mating cycles. This is critical for 74-position interfaces in test equipment or field-replaceable modules operating in temperatures from -55°C to +125°C.
