TRS Thermal Reed Switch
Overview
Applications
The TRS Thermal Reed Switch is a highly reliable, precise
temperature-sensitive switch ideal for energy conservation.
Its unique proprietary design features a magnet and
a temperature-sensing soft ferromagnetic substance
called Thermorite®. The material’s magnetic flux density
decreases as the temperature increases turning it into a
paramagnetic substance at the Curie temperature.
Typical applications include temperature detection and
overheat monitoring of electric appliances, heat-retention
heater control for rice cookers, defrost for air conditioners
and vending machines, roll heater temperature control for
copying machines, radiator water temperature detection for
automotive electric fan control.
These products have also been attested by the International
Relay Association.
Benefits
• High reliability for on/off operations
• High-speed response
• Long operational life
• Excellent environmental durability
• Extremely simple circuit design
• Compact, light and easy to handle
• Dust, explosion and corrosion-proof
Axial Type
• Wide range of operating temperatures available
from −10°C to +130°C
• Excellent temperature accuracy of ±2.5°C
• UL and CSA approved for TRS5***BLRU 100V
• UL approved for TRS5***BLRVU 200V
• RoHS/REACH compliant
