Normally Closed (NC) switches open when the set temperature is reached, typically used for safety cut-offs. Normally Open (NO) switches close when the temperature is reached, typically used to trigger fans or alarms.
Temperature Sensors - Thermostats - Mechanical - Industrial Component Intelligence
Rugged thermal switches for reliable over-temperature protection and control.
What are Temperature Sensors - Thermostats - Mechanical - Industrial components?
Mechanical industrial thermostats use bimetallic elements to provide simple, robust, and often self-resetting thermal switching. They are essential for direct over-temperature protection in power supplies, motors, and HVAC systems where electronic sensing is not required.
How to Choose Temperature Sensors - Thermostats - Mechanical - Industrial Components
Select based on the physical mounting, thermal response time, and electrical load requirements.
Contact Configuration
Choose between Normally Closed (NC) for over-temp protection or Normally Open (NO) for cooling control.
Temperature Tolerance
Verify the operating temperature range and the differential (hysteresis) required for your specific cycle.
Current/Voltage Rating
Ensure the switch contact rating exceeds your peak load current to prevent contact welding.
Mounting Style
Match the physical package—surface mount, stud mount, or probe—to your thermal interface.
Reset Type
Decide between automatic reset for continuous operation or manual reset for safety-critical fault latching.
