Frequently Asked Questions

What is the contact pitch of the SQW-120-01-L-D-VS-K-TR and how does it affect PCB layout density?

The SQW-120-01-L-D-VS-K-TR uses a 2.00mm pitch, allowing 40 positions to span roughly 38mm, which balances connector density with adequate clearance for standard PCB trace routing and via placement.

Which industrial or embedded applications benefit most from the SQW-120-01-L-D-VS-K-TR socket?

This 40-position dual-row socket with 2.00mm pitch suits industrial controllers, embedded backplane modules, and data acquisition boards where a rugged, cost-effective board-to-board connection with gold-over-nickel contacts is required.

How does the gold-over-nickel contact finish on the SQW-120-01-L-D-VS-K-TR compare to standard tin contacts for long-term reliability?

The 10 µin gold over 50 µin nickel mating finish offers significantly lower contact resistance and better corrosion resistance than tin contacts, supporting more than 100 mating cycles with stable electrical performance.
