Frequently Asked Questions
What contact finish does the FTSH-125-01-L-DV-EJ-K-P-TR use, and how does it affect connector longevity?
The FTSH-125-01-L-DV-EJ-K-P-TR uses gold (10 µin) over nickel (50 µin) mating contacts, which provides excellent corrosion resistance and low contact resistance over many mating cycles. This finish is well-suited for test equipment and instrumentation where connectors are repeatedly mated and demated, ensuring stable signal quality is maintained throughout the product lifecycle.
How does the polarized design of the FTSH-125-01-L-DV-EJ-K-P-TR prevent assembly errors in production?
The polarized connector body of the FTSH-125-01-L-DV-EJ-K-P-TR physically prevents incorrect mating orientation, which is critical when handling 50-pin dual-row configurations during board assembly and system integration. This design feature eliminates the risk of reversed insertion damage to connected circuits, reducing rework costs in high-volume PCB production and field service operations.
What board space does the FTSH-125-01-L-DV-EJ-K-P-TR occupy, and which embedded computing designs benefit most?
The FTSH-125-01-L-DV-EJ-K-P-TR has a body length of 1.25 inches and a body breadth of 0.135 inch, making it compact enough for high-density embedded computing boards, FPGA mezzanine cards, and SOM carrier boards where 50 signals must be routed between boards in a constrained footprint. Its dual-row layout maximizes pin count per unit length compared to single-row alternatives.
