Frequently Asked Questions
What gold plating thickness do the mating contacts of SFM-118-02-S-D have, and why does it matter?
The SFM-118-02-S-D features 30 µin (microinches) gold plating on its mating contacts over a nickel underplate, providing robust corrosion protection and stable low contact resistance over many mating cycles. This plating level meets requirements for high-reliability applications where contact resistance must remain below specified limits across all 36 positions.
How does the 0.050-inch pitch of the SFM-118-02-S-D help reduce PCB footprint in a 36-signal design?
At 0.050-inch (1.27 mm) pitch, the SFM-118-02-S-D places 36 contacts within a 1.055-inch body length — roughly half the footprint of an equivalent 0.100-inch pitch socket. This density benefit is critical in space-constrained mezzanine modules and compact industrial PCBs where routing 36 signals in minimal board area is a design priority.
For a high-speed data acquisition module, is the SFM-118-02-S-D suitable and what body dimensions should the layout engineer plan for?
Yes, the SFM-118-02-S-D suits high-speed data acquisition applications where its 0.145-inch body breadth and 0.185-inch body depth minimize the keep-out zone adjacent to the connector footprint. The 1.055-inch body length accommodates 36 positions in dual rows, making it a practical choice when signal line counts and board space requirements both need to be tightly managed.
