Terminal pins are fitted with cylindrical insulating sleeves

MILL-MAX Six terminal pins and receptacles are fitted with cylindrical insulating sleeves for electrical isolation applications. Product lineup includes three header pins, two receptacles and one solder cup pin to suit a variety of uses. Insulated terminals are used to electrically isolate single pin interconnects from surrounding conductive components or elements in an assembly. The plastic sleeve provides insulation of the terminal for such applications where the pin/receptacle must pass through a conductive housing without coming in contact with it or where a pin/receptacle, installed on a board, needs to be protected from nearby conductive components. http://www.mill-max.com
