RT24 Surface Temperature Sensor


  • Low cost surface temperature sensor
  • Fast response, excellent thermal tracking
  • High accuracy thermister
  • Wide operating temperature range: -40°C to 150°C
  • 2000 Volt isolation sensor to terminal
  • #6 stud (0.144" diameter) hole size


The Model RT24 is a low cost surface temperature sensor which provides a fast response time and excellent thermal tracking. 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.
