PTC Thermistor Temperature Sensor for Motor Protection | Self-Regulating Thermal Sensor
Our PTC Thermistor Temperature Sensor provides reliable temperature monitoring and built-in over-temperature protection for a wide range of industrial and commercial equipment.
Using a Positive Temperature Coefficient (PTC) sensing element, the resistance increases rapidly when the temperature reaches a specified threshold, effectively limiting current and protecting systems from overheating.
Designed for durability and long-term stability, this sensor is ideal for motors, transformers, power electronics, HVAC systems, and other temperature-critical applications.
Product Description：
The PTC thermistor temperature sensor combines accurate temperature detection with automatic thermal protection. When the operating temperature exceeds the rated switching point, the resistance rises sharply, triggering protective action in control circuits or monitoring systems. Its simple structure, fast response, and maintenance-free operation make it a cost-effective and dependable thermal safety solution.
Advantages of PTC Thermistor：
Self-regulating over-temperature protection
Rapid resistance increase at preset switching temperature
Fast thermal response for real-time monitoring
High reliability and excellent long-term stability
Wide operating temperature range
Compact structure for easy installation
Strong resistance to vibration, moisture, and electrical stress
Customizable switching temperature, cable length, and connector type
Compatible with standard motor protection relays and control systems
