Normally Open (NO) thermostats close the circuit when the set temperature is reached, often used for cooling fans. Normally Closed (NC) thermostats open the circuit when the set temperature is reached, typically used for thermal safety cut-offs.
Temperature Sensors - Thermostats - Mechanical Component Intelligence
Robust, self-contained thermal switching solutions for safety and control.
What are Temperature Sensors - Thermostats - Mechanical components?
Mechanical thermostats are bimetallic switches that provide passive, reliable thermal protection. They operate by using the differential expansion of two metals to open or close a circuit at a fixed temperature, requiring no external power or complex control logic.
How to Choose Temperature Sensors - Thermostats - Mechanical Components
Selecting the right mechanical thermostat requires balancing thermal response time with electrical load requirements.
Switching Temperature
Define the precise opening/closing setpoint and the required tolerance (hysteresis) for your application.
Electrical Rating
Ensure the contact ratings (voltage and current) exceed your maximum load to prevent welding or arcing.
Mounting Style
Choose between surface-mount, probe, or stud-mount configurations based on the thermal coupling required.
Contact Configuration
Select Normally Open (NO) or Normally Closed (NC) based on your fail-safe requirements.
Environmental Sealing
Verify if the application requires hermetic sealing to protect against moisture or contaminants.
