Polarized plug and jack assembly bodies are made from molded glass-filled thermoset compounds, with copper pin material. The connector is color-coded white. A metal ferrule tube adapter secures the probe in place, and a wire clamp is used to hold the wire. Standard assemblies are designed to operate in temperatures up to 300° F (150° C). High temperature assemblies operate up to 800° F (427° C) and are color-coded red. Polarity marks are molded in the bodies for installation assistance. Individual plugs, jacks, tube adapters and wire clamps are also available.
