Key Features & Advantage:

Robust Thru-Hole Mechanical Anchoring: Solder tails penetrate directly into the PCB, providing supreme retention force and structural integrity capable of withstanding severe pulling, mating cycles, and industrial vibrations.
Wider 4.0mm Pitch for Superior Electrical Isolation: The expanded 4.0mm spacing increases the creepage and clearance distances between circuits, preventing electrical arcing and crosstalk in rugged power or signal layouts.
Premium Flat Blade Pin Geometry: Stamped flat pin configuration 1.20mm * 0.60 mm offers a larger surface contact area than conventional square pins, ensuring lower contact resistance and increased current reliability.
