High-quality customized sensors, thermal switches, and fuse services
Thermal switches (thermal fuse) and Temperature Sensor have to work in a fail-safe manner under any circumstances. Their natural operating environment includes cold, heat and humidity.
A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (thermal fuse), or may be reset manually or automatically ( thermal switch).
A temperature sensor is a device that detects and measures hotness and coolness and converts it into an electrical signal. At YAXUN, we design and manufacture a broad portfolio of temperature sensors – including our NTC thermistors, RTDs, PT100/PT1000, and Ds18b20 – designed for efficiency and easy installation, with capacity to reliably integrate technology that responds to human behavior.
temperature sensor probe
Temperature probe assembly are used to make measurements of air, liquid or surface temperatures and are available in various forms such as thermocouple, thermistor (NTC) and PT100 to complement thermometers and temperature data logging instrumentation.
Thermal cut-off switch
A thermal switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change. This thermal cutout (Automatic/manual reset) has a bimetal strip and a beryllium copper blade and the operating mechanism is based on the snap action disc thermostat (NC/NO).
Thermal fuse & current fuse
Unlike electrical fuses or thermal fuses, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature. A thermal fuse is like a mechanical switch that is spring-loaded to stay in the open position. An electrical fuse is essentially a thermal fuse with a well-established resistance and dissipation profile, and the current at which it fuses
Fuse boxes and fuse holders
Automotive/electrical fuse holders/boxes are holders used to install fuses, and their broad categories can be divided into: panel-mounted fuse holders, PCB-mounted fuse holders, lead-type fuse holders, rail-type fuse holders and automotive fuse holders. The fuse box is a box used to install fuses and has performance characteristics such as waterproof, fireproof, and high temperature resistance. According to different materials and shapes, fuse boxes can be divided into lead-type fuse boxes and fuse holders.

NTC Thermistor Sensor Packaging and Selection
When selecting a thermistor, it is indeed necessary to comprehensively consider many key parameters and packaging (epoxy resin Encapsulation, Glass Bead Encapsulation, thin film Encapsulation, SMD Encapsulation, stainless steel probe sensor Encapsulation, injection molding coating). Let me tell you in detail:
Resistance Range and Application of Thermistors
The resistance range of thermistors is wide, and the resistance of NTC thermistors can range from tens of ohms to ten thousand ohms, and even special devices can be customized according to needs. Commonly used resistance values are 2.5Ω, 5Ω, 10Ω, etc., and common resistance errors are ±15%, ±20%, ±30%, etc. The resistance range of PTC thermistors is usually from 1KΩ to hundreds of KΩ.
Accuracy and Response Time of Thermistor Sensors
Reasonable arrangement of temperature sensors: The location and arrangement of temperature sensors will also affect the response time. If the contact area between the sensor and the object being measured is large, the heat exchange will be faster and the response time will naturally be shorter. However, please note that too large a contact area may also lead to increased measurement errors, so we have to make a trade-off based on the actual situation.
Several Application Cases of Thermistor Sensors
As a component that can change the resistance value according to temperature changes, thermistors have a wide range of applications (such as temperature measurement, temperature control, temperature compensation, temperature alarm, battery thermal protection). Let me share with you several application cases of thermistors:
Wiring of NTC Thermistor Temperature Sensor
The connection method of the NTC thermistor temperature sensor needs to be determined according to the actual application scenario and measurement requirements. During the wiring process, be sure to pay attention to the pin polarity, wire selection, temperature range, filtering and decoupling, grounding treatment, and verification and calibration to ensure the accuracy and reliability of the measurement.
