Frequently Asked Questions
How many positions does the MLE-126-01-G-DV-A provide and what is its contact pitch?
The MLE-126-01-G-DV-A provides 52 positions arranged in a single-beam configuration with a 1.00 mm Tiger Beam pitch. This compact pitch allows designers to achieve high pin counts in a board footprint less than 26 mm long, enabling dense interconnects in space-constrained PCBs.
What contact plating does the MLE-126-01-G-DV-A use and why does it matter for signal integrity?
The mating contacts feature gold (10 µin) over nickel plating, which provides low and stable contact resistance across all 52 positions. Gold resists oxidation and maintains reliable electrical performance through at least 500 mating cycles, critical in automated test and instrumentation applications.
When should engineers choose MLE-126-01-G-DV-A over a 2.00 mm pitch connector for the same application?
The 1.00 mm Tiger Beam pitch is preferred when PCB area is constrained and 52 or more signals must be routed between boards within a 26 mm connector length. Compared to a 2.00 mm pitch alternative requiring 52 mm of board edge, the MLE-126-01-G-DV-A reduces connector footprint by approximately 50%, freeing space for routing or additional components.
How do the solder holding posts on MLE-126-01-G-DV-A aid PCB assembly?
The integrated solder holding posts mechanically lock the connector body to the PCB during reflow soldering, preventing tilt or float at temperatures up to 260°C. This ensures all 52 contacts remain coplanar and within the solder paste deposit, improving first-pass yield in automated SMT assembly.
