What are the key features of QTT-111-02-L-T?
- 33-position single-row power plane terminal strip on 2.00 mm pitch for high-density board stacking signal and power interconnects
- 10 µin gold-over-nickel mating finish on phosphor bronze contacts delivers low contact resistance and corrosion resistance across hundreds of mating cycles
- Board stacking connector design enables secure mechanical and electrical connection between stacked PCBs without additional hardware
- Tin-over-nickel termination finish on the solder tail ensures reliable soldering with standard lead-free reflow profiles
What is QTT-111-02-L-T used for?
QTT-111-02-L-T is suited for board-to-board stacking configurations in compact embedded systems, industrial I/O modules, and communications equipment where 33 power or signal lines must bridge two PCBs on a 2.00 mm pitch. Its gold-over-nickel mating contacts withstand repeated engagement cycles, making it a reliable choice for field-replaceable module systems and development platforms with interchangeable daughter cards. The power plane terminal strip format ensures stable high-current distribution across stacked boards in space-constrained enclosures.

Frequently Asked Questions
What contact finish does QTT-111-02-L-T use on its mating surfaces, and why is this important for contact resistance?
QTT-111-02-L-T uses a 10 µin gold-over-nickel finish on the mating contacts. Gold at this thickness provides low and stable contact resistance even after hundreds of mating cycles, and the nickel underplate acts as a diffusion barrier that prevents base metal migration into the gold layer over time, which is critical for reliable signal integrity in board stacking power plane applications.
How many positions does QTT-111-02-L-T provide, and what pitch spacing is used between contacts?
QTT-111-02-L-T provides 33 positions on a 2.00 mm pitch in a single-row configuration. The 2.00 mm pitch occupies a 0.879 inch body length, offering a balance between contact density and solderability for power plane terminal strip applications in industrial and embedded board stacking designs.
What base contact material is used in QTT-111-02-L-T, and how does it affect spring force and durability?
QTT-111-02-L-T contacts are made from phosphor bronze, a copper alloy with excellent spring properties and fatigue resistance. Phosphor bronze maintains consistent spring force across the 33-position interface even after repeated mating cycles, ensuring stable 2.00 mm pitch board stacking connections in industrial environments with vibration or thermal cycling.
