The aeco AT4-1812S is a very high-quality Jack 4.4mm TRRRS connector, designed using high-performance components for optimum transmission of the audio signal. Its contacts are CNC machined from a single piece of high-purity tellurium copper with 120µ silver plating ensuring maximal conductivity and limiting signal loss. In addition, this model allows convenient mounting of a cable (max Ø6.5mm) thanks to parallel-oriented solder pins. Finally, the stainless steel body is insulated from the contacts by a nylon section.
