Frequently Asked Questions
Why does the SQT-120-01-S-D use gold-plated mating contacts rather than tin for a rugged PCB socket?
Gold-plated mating contacts on the SQT-120-01-S-D provide significantly lower contact resistance and greater corrosion resistance than tin, which is critical for 40-position rugged PCB sockets expected to endure many mating cycles. Gold is rated to maintain stable conductivity across hundreds to thousands of insertions at operating temperatures typically ranging from -55°C to +125°C.
What is the pitch and body size of the SAMTEC SQT-120-01-S-D socket connector?
The SQT-120-01-S-D uses a 2.00 mm pitch dual-row layout. The body is 1.586 inches long, 0.157 inches wide, and 0.079 inches deep. This compact profile suits dense PCB layouts while providing 40 positions for board-to-board signal connections in industrial and computing equipment.
What lead time should procurement teams plan for when ordering the SAMTEC SQT-120-01-S-D?
SAMTEC lists a factory lead time of 6 weeks for the SQT-120-01-S-D. Procurement teams should factor this into supply chain planning, particularly for new product introductions or volume orders. Stocking buffer inventory is advisable for production lines that cannot tolerate 6-week delivery windows.
In which applications is the SAMTEC SQT-120-01-S-D most commonly specified as a rugged socket connector?
SQT-120-01-S-D is commonly specified in rugged industrial computers, modular test fixtures, and backplane systems where a 2.00 mm pitch, 40-position board-to-board socket must withstand repeated insertion cycles. Its gold mating contacts and tin-nickel termination finish suit harsh-environment deployments operating from -55°C to +125°C.
