Frequently Asked Questions
How many positions does LTH-050-01-G-D-A-K provide, and what pitch spacing is used for this board stacking connector?
LTH-050-01-G-D-A-K offers 50 positions in a dual-row configuration with 0.050-inch (1.27mm) pitch spacing. The 1.15-inch body length accommodates all 50 contacts in a compact dual-row layout, suitable for high-density signal routing between stacked PCBs in embedded computing and test equipment designs.
What contact finish does LTH-050-01-G-D-A-K use, and how does it affect connector reliability in high-cycle applications?
LTH-050-01-G-D-A-K uses gold (Au) contact finish on mating surfaces with a nickel (Ni) barrier on termination contacts. Gold plating provides low contact resistance typically below 10 milliohms and excellent corrosion resistance, supporting hundreds of mating cycles while maintaining reliable electrical performance in demanding environments.
Which board mounting method does LTH-050-01-G-D-A-K use, and what advantage does peg mounting provide during PCB assembly?
LTH-050-01-G-D-A-K uses a peg board mounting option with 0.066-inch body depth. The mounting pegs insert into PCB holes to mechanically fix the connector before soldering, preventing misalignment during reflow. This ensures all 50 positions maintain accurate 0.050-inch pitch registration across the 1.15-inch body length during assembly.
