Frequently Asked Questions
How many contacts does SFM-145-02-FM-D-A-P carry and what pitch do they use?
SFM-145-02-FM-D-A-P provides 90 contacts arranged in a dual-row pattern on a 0.050-inch (1.27 mm) pitch. This high-density layout supports routing large parallel buses, multiple power rails, and control signals through a single SMT connector footprint suitable for mezzanine card designs.
What makes SFM-145-02-FM-D-A-P suitable for repeated mating cycles in industrial deployments?
SAMTEC's SFM high-reliability series is engineered for repeated insertion and extraction cycles without significant degradation in contact resistance. The female socket contacts maintain controlled spring force across 90 pins, making the connector reliable for field-replaceable mezzanine modules in industrial PLC backplanes, test instrumentation, and avionics chassis requiring MSL-compliant storage and assembly.
Which mating header series pairs with SFM-145-02-FM-D-A-P to form a complete board stack?
SFM-145-02-FM-D-A-P mates with SAMTEC's SMM or TFM series 0.050-inch pitch male headers. The mating header stacking height can be selected from approximately 4 mm to 20 mm depending on board separation requirements, allowing designers to configure the mezzanine gap for their specific thermal management or component clearance needs across the 90-position interface.
How does the 0.050-inch pitch of SFM-145-02-FM-D-A-P compare to standard 0.100-inch pitch connectors for PCB routing?
The 0.050-inch (1.27 mm) pitch of SFM-145-02-FM-D-A-P is half that of the common 2.54 mm pitch, so the 90-position dual-row connector occupies roughly the same board footprint as a 45-position 2.54 mm strip. This density advantage is critical in compact systems where PCB real estate for a 90-signal interface is constrained.
