SM2-CR Self Regulating Heating Cable

SM2-CR Self-Regulating Heating Cable

Unlike ordinary metal resistance wire which produces heat output corresponding to its length, the core of SM2-CR is composed of the infinite parallel connection of carbon particles. The parallel circuitry allows the cable to be cut to the exact length required, with no wasted cable.

SM2-CR consists of a continuous core of conductive polymer extruded between two copper bus wires.

SM2-CR regulates its own heat output in response to ambient temperatures as electrical current flows through the core. The self-regulating function of the core is due to its PTC (Positive Temperature Coefficient) property by which the electrical consumption of SM2-CR is reduced in the application.
