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 temperaturesensing 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.

Magnetic Direct Current Sensor MDCS®
Outline
Magnetic direct current sensors (MDCS®) use a magnetic
substance and hole device for magnetic detection of
direct current. They detect all currents (DC, AC and
pulse), and the output voltage varies in proportion to the
strength of the current measured.
Features
• Detection of both direct currents and alternating currents (including pulse currents)
• Fluctuations in output from changes in the power
supply voltage and the ambient temperature are small.
• Excellent linearity of measured current and the converted power output
• The measured current and the secondary output side are
insulated.
Applications
• Inverter-based home appliances (Air-conditioners etc.)
• General-purpose inverters
• AC variable-speed drive and servo drive
• Industrial machines • UPS • DC motor control
• FAX and other multifunction telephone series (THS Series)

Before Using Magnetic Direct Current Sensor MDCS®
• Strong physical shocks could damage cores. Be careful not to drop or apply other strong impact.
• These products are heat resistant up to 260°C for 10 seconds. Be careful not to exceed this amount when
soldering. Use a low-corrosion type flux when soldering.
• Because the circuit uses ICs, application of strong static electricity could cause damage. Take static electricity
precautions when handling.
• Because these products are magnetic current detectors, application of strong external magnetic fields could
cause their characteristics to change. Limit ambient magnetic fields to 50e or less.

1) Since a residual carrier noise may be included in the output voltage (between Vref and Vout),
it is necessary to connect a low pass filter for higher harmonic component elimination.
2) A high pass filter is generally connected for eliminating the influence of output voltage fluctuation (by temperature, etc.) in stationary state.
3) It is recommended to ground the Vref terminal with a capacitance of 4.7μF to stabilize the
Vref output.
Before Using Ceramic Gyro
• When transporting or handling a sensor, be careful not to drop it or subject it to any other physical shock.
Failure to do so may lead to internal damage or deterioration of its characteristics.
• Avoid applying mounting voltages higher than the rating to the sensors pins. This will lead to overheating
or damage to the sensors.
• As sensors are not water resistant, cleaning should be avoided.
• When handling sensors, anti-electrostatic precautions must be taken.

Before Using Proximity Switch Series
Fixing the Proximity Switch
When fixing a proximity switch, avoid warping as shown in Figure 1 caused by rise of filler or an obstacle left
on the mounting surface. Also, do not pull a reed wire.
Obstacle
Figure 1 Warping caused by an obstacle left between the proximity switch and the mounting surface.
Cautions for Shock
(1) As the characteristics of the proximity switch (especially sensitive) may deteriorate when the switch falls
from above 30cm height, caution must be taken.
(2) If many proximity switches are mounted on a large print board, caution must be taken when cutting the print
board along the perforated line, because the shock of cutting may change the sensitivity of the switch.
(Along with an effort such as leaving the least part to reduce the shock, we recommend that you confirm that
the sensitivity has not changed before use.)
Contact Protection Circuit
For improving the reliability of the proximity switch, insert one of the following contact protection circuits when
using the switch at a load which causes a surge current.
• Inductive load
If an inductance (coil, electromagnetic relay, motor, etc.) is used as a load, hundred of volts of counter
electromotive force (the energy stored in the inductance) will occur to shorten the lifetime of the contact (for
the resistance load, that is also true when an inductance is used at a high voltage or a large current). For
protection circuits, refer to Figure 2.

• Capacity load
If a condenser is used as a load, charge/discharge at the capacitance will cause a rush current when the switch
is closed, which may make switch opening impossible. In this case, as shown in Figure 3, the method in which
a protection resistance R is inserted can be used.

• Lamp load
In general, the filament of the lamp is made of tungsten. With the tungsten filament, the resistance is low when
the lamp is turned on and becomes higher as it reaches the stationary current. When this lamp is used with a
proximity switch, a rush current (at five to ten times the stationary current) will be caused immediately after
lighting, which may result in welding or adhering of the contact. In this case, as shown in Figure 4, a protection
resistor R can be inserted .

• Wiring capacity load
If a contact and a load are combined by long wires or cable, the floating capacity will cause a rush current when
the contact is closed, which largely affects the lifetime of the contact. In this case, as shown in Figure 5, a
protection circuit in which a resistance or inductance is added can be used.

Cautions for Ultrasonic
• Ultrasonic cleaning
After mounting a proximity switch on a printed circuit board or the like, avoid ultrasonic cleaning because
ultrasonic cleaning may change the sensitivity of the switch or crack the seal of the glass tube.
• Ultrasonic welding
Also, avoid ultrasonic welding because, by the same reason as ultrasonic cleaning, the performance of the
proximity switch may deteriorate.
