Frequently Asked Questions
How many positions does the SFM-143-T2-S-D have, and what is the connector pitch?
The SFM-143-T2-S-D provides 86 positions in a single-row surface mount socket strip with a 0.050" (1.27 mm) pitch. This single-row 1.27 mm pitch configuration is used in applications requiring a large number of signal connections along one edge of a PCB, including expansion module sockets and plug-in card interfaces.
For a module that will be frequently swapped during field maintenance, how does the SFM-143-T2-S-D hold up over repeated insertions?
The SFM-143-T2-S-D features precision gold-plated contacts rated for 500 or more mating cycles while maintaining contact resistance below 20 milliohms. This makes it suitable for field-replaceable modules in industrial control panels and telecommunications line cards where connectors must withstand repeated insertions without degradation in signal integrity.
Is the SFM-143-T2-S-D processable through a standard SMT reflow oven without additional assembly steps?
Yes, the SFM-143-T2-S-D is a surface mount component compatible with standard automated pick-and-place assembly and reflow soldering at peak temperatures up to 260°C. No additional through-hole soldering or hand soldering is required, streamlining integration into high-volume PCB production lines for telecommunications and industrial electronics.
When would an engineer choose the 86-position single-row SFM-143-T2-S-D over a dual-row socket with fewer positions per row?
An engineer selects the SFM-143-T2-S-D single-row 86-position format when the PCB layout requires all contacts along one axis, such as for edge-card sockets or long single-row module connectors. Compared to dual-row alternatives, the single-row format reduces connector width to approximately 1.27 mm per pin, providing a narrower profile ideal for slim PCB card designs in server blades and compact instrumentation.
