All Kapton-insulated Hot Disk® sensors can be acquired with or without attached cables. The standard cables can be used in a temperature range of -20 to +50 °C while silicone cables are available for use in the wider range of -60 to +180 °C. Sensors without cable can be mounted in dedicated sensor holders for use up to 300 °C (400 °C in vacuum or oxygen-free environment).
