The aeco AT4-1812R is a 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 rhodium plating ensuring excellent conductivity and limiting signal loss while protecting it from oxidation. 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.
