TRS Thermal Reed Switch, Screw Type
Overview
Applications
The TRS Thermal Reed Switch is a highly reliable, precise
temperature-sensitive switch ideal for energy conservation.
The screw mounting package of TRS-P makes it easy to set
up in the application, by just screwing it in the device that
needs temperature detection or overheat monitoring.
Typical applications include radiator water detection
and overheat detection for industrial, agricultural and
automotive engines.
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.
These products have also been attested by the International
Relay Association.
Benefits

Structures and Principles of Operation
Thermal Reed Switches (TRS) are temperature-sensing switches composed of a magnet and a temperature-sensing soft
ferromagnetic substance called Thermorite. This material’s saturation magnetic flux density decreases as the temperature
increases, and it turns into a paramagnetic substance at its Curie temperature.
Thermorite properties
• Thermorite changes its magnetic property rapidly at its Curie temperature, providing quick response times.
• The Curie temperature of Thermorite does not vary with time, as it is based on a compounding ratio.
• Thermorite is stable against moisture and hazardous gas.

Structures and Principles of Operation cont.
Reed switch structure
Encasing
• The reed switch is a contact switch comprised of a pair of Fe-Ni alloy
reeds encased in a glass tube with inactive gas. The reeds are switched
on or off by the magnetic field of a permanent magnet or magnet coil.
• The reeds in the glass tube become magnetized from the magnetic
field, allowing the two reeds to make contact and connect (switch on).
When the magnetic field disappears, the reeds separate and disconnect
(switch off).

Handling Precautions
Precautions to be taken when using Thermal Reed Switches
(Please read these precautions before using our products)
• Do NOT use in close proximity to strong magnetic parts.
• Do NOT use product under mechanical weight load.
• Do NOT use if dropped or severely shocked.
• Do NOT use with a greater load than specified.
• Avoid stress (especially torsion) in case of additional processing.
• Thermal Reed Switches have a specific resonance frequency.
Please contact a KEMET representative if an oscillation is added.
