Fanox PTC Sensor

PTC 70 External Thermistor Sensor

SKU 41705
Fanox PTC Thermistor Sensors provide secondary thermal defense for motors, detecting internal heat that external relays might miss. By embedding these sensors directly into the motor windings, you get a direct temperature reading that protects against ambient heat, cooling failures, and blocked ventilation. These sensors are a vital secondary defense for any high-duty motor installation.
