Frequently Asked Questions
What contact finish does the QTT-112-02-L-T use on its mating and termination surfaces?
The QTT-112-02-L-T uses 10 µin gold over nickel on the mating interface to ensure low contact resistance and corrosion resistance. The termination end is finished with tin over a nickel barrier, providing excellent solderability to PCB pads during reflow or wave soldering processes.
How many positions does QTT-112-02-L-T provide and what is its board-stacking pitch?
The QTT-112-02-L-T provides 36 positions at a 2.00 mm pitch arranged as a board-stacking connector measuring approximately 0.958 inches long. This layout enables connection of 36 power or signal lines between two stacked PCBs in compact industrial, motor-drive, or embedded computer assemblies.
Why is phosphor-bronze used for the QTT-112-02-L-T contacts rather than brass?
Phosphor bronze provides higher spring force and better fatigue resistance than standard brass, maintaining reliable contact pressure across hundreds of mating cycles and under mechanical vibration. In board-stacking power-plane applications with 36 contacts, the superior elasticity of phosphor bronze ensures that each pin retains consistent normal force, reducing micro-arcing and contact resistance over the product lifetime.
