INTRODUCTION
Advances in LSls, microcomputers and power devices enable ever more efficient use of energy, finer control and greater ease
of use. In this way industry is promoting consumer appliances with increasingly sophisticated
“intelligent”
functions. And with these
developments there is a burgeoning need for advanced, highly reliable sensors with capabilities corresponding to the human’ five
senses.
NEC TOKIN seeks to commercialize creative products fusing new material technologies with new applications, developing
and commercializing a broad range of sensor devices based on outstanding materials technologies covering properties such as
magnetism, piezoelectronics and optics.
This catalog introduces different kinds of sensors, including thermosensors, current sensors and magnetic sensors. Besides the
items shown here we also offer an extensive line of sensor-related products and are continually developing new sensors, so please
feel free to ask us about anything you might need. We look forward to being able to serve you.

Outline
NEC TOKIN led the world in recognizing and realizing
the potential of ferrite's Curie temperature. The result is
Thermorite
®
, a temperature-sensing magnetic material.
Ever since the introduction of this product, NEC TOKIN
has reigned as the top manufacturer of Curie-temperature-
utilizing control devices, developing many products with
new functions. Among these, the Thermal Reed Switch
(TRS
®
) is the chief product, with patents in the United
States and Japan. Its superiority as a highly reliable,
precise temperature-sensitive switch ideal for promoting
energy conservation has been attested to by the
International Relay Association. There are already more
than 300 million in use, and with the addition of TRS
®
varieties approved by UL, CSA and other safety
standards, the lineup just keeps getting better.

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 the Curie
temperature.

Before Using Thermal Reed Switch (TRS
®
)
• Please ask for a copy of specification and check the contents thoroughly before the actual use.
• Please contact us before deciding your specifications.
• Do not use in close proximity to strongly magnetized parts.
• Do not use if dropped or strongly shocked.
• Do NOT use with greater load than specified.
When installing these switches in circuits prone to producing surge voltage (inductive load) or rush current
(in lamps and motors), an appropriate switch type should be used, or a contact point protection circuit added.
• Avoid stress (especially torsion) in case of additional processing.
• Each reed switch has a specific resonance frequency. Please contact us when an oscillation is added.
