It operates over a wide temperature range and can be used to monitor the temperature of heat sinks, power transistors, or any flat surface that requires thermal overload protection. The RT24 consists of a highly stable NTC thermistor epoxied to a tin-plated copper ring lug terminal. The sensor leads are AWG#24 wires with kynar insulation. A heat shrinkable sleeve is used to provide strain relief and to guarantee 2000 volt isolation between the sensor and the mounting terminal.
