INSULATED
Hot junction insulated from sheath. Gives floating output with typical insulation resistance in excess of 100 megohms

Assemblies with pot seals are supplied with short tails as shown. However, where leads are several metres or more long, it is more suitable to have an overall sheathed cable. We recommend the following cables.
