Frequently Asked Questions
What is the contact finish specification of the QTE-040-07-L-D-A and why does it matter for mating reliability?
The QTE-040-07-L-D-A uses gold (10 µin) over nickel (50 µin) contact plating, which provides contact resistance below 20 mΩ and sustains reliable electrical performance over repeated mating cycles without oxidation in standard industrial environments.
How does the QTE-040-07-L-D-A prevent mis-mating in a multi-connector stacking design?
This connector incorporates a polarized E.L.P. (Extended Latching Post) and peg-mount board anchor that physically prevent incorrect orientation during assembly, ensuring all 80 positions are correctly aligned before mating force is applied, reducing assembly errors in high-volume production.
For a 7-row stacking height design, which SAMTEC QTE variant should be specified?
The QTE-040-07-L-D-A suffix -07 designates a 7-row stacking height configuration, providing a board-to-board stack height compatible with PCB separations in the range of approximately 7 mm, suitable for module designs where specific vertical clearance is required between two stacked boards.
