Frequently Asked Questions
How does the 2.00 mm pitch of the SQW-110-01-F-D-VS-K-TR compare to 2.54 mm pitch alternatives for space-constrained industrial PCBs?
The 2.00 mm pitch reduces the connector footprint length by approximately 21 % compared with a 2.54 mm pitch equivalent for the same 20-position, dual-row count, allowing denser placement on space-constrained industrial PCBs while still accommodating standard SMT reflow soldering processes.
What mating contact finish does the SQW-110-01-F-D-VS-K-TR use, and how does it affect insertion cycle life?
The SQW-110-01-F-D-VS-K-TR uses gold flash (3 micro-inch minimum) on the mating interface with a nickel barrier over matte tin termination, which typically supports dozens of insertion cycles and provides adequate corrosion protection for sockets in climate-controlled environments.
For a daughter card that must mate and de-mate frequently during firmware development, is the SQW-110-01-F-D-VS-K-TR a suitable socket?
For high-cycle development scenarios requiring hundreds of insertions, a heavier gold plating grade connector from Samtec's SQW or SSW series with selective gold contacts may be more appropriate; the SQW-110-01-F-D-VS-K-TR gold flash finish is optimized for lower-cycle production mating rather than 500-plus insertion cycle lab use.
