This pair of AECO AMI-1060S connectors consists of a male XLR connector and a female XLR connector. These 3-pole XLR connectors feature a "one-point contact" structure with tellurium copper contacts and PTFE insulation. They accept cables with a maximum external diameter of Ø12mm, and a sleeve allows the insertion hole to be tightened to Ø8.5mm. Contacts are made of tellurium copper with 120u silver plating for corrosion and oxidation resistance, as well as enhanced conductivity.
