NOTES
1. For general cautions for use, please
refer to the “General Application
Guidelines”.
2. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be
rectangular. If it includes ripple, the ripple
factor should be less than 5%.
However, check it with the actual circuit
since the characteristics may be slightly
different. The nominal operating voltage
should be applied to the coil for more
than 50 ms to set/reset the latching type.
Please use the latching type for circuits
that are continually powered for long
periods of time.
3. Coil connection
Since this product is polarized, please be
aware of the plus/minus polarity of the
coil.
4. Connection and washing conditions
for coil and PIN type contact terminals
1) The connection of coil and PIN type
contact terminals shall be done by
soldering.
Soldering conditions
Max. 260°C 500°F (solder temp) within
10sec (soldering time)
Max. 350°C 662°F (solder temp) within
3sec (soldering time)
2) This product is not sealed type,
therefore washing is not allowed.
5. Conditions for operation, transport
and storage conditions
1) Temperature:
–55 to +85°C –67 to +185°F
2) Humidity: 5 to 85% RH
(Avoid freezing and condensation.)
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.
3) Atmospheric pressure: 86 to 106 kPa
Temperature and humidity range for
usage, transport, and storage:
4) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
deterioration of coaxial switch insulation.
5) Freezing
Condensation or other moisture may
freeze on coaxial switch when the
temperature is lower than 0°C 32°F. This
causes problems such as sticking of
movable parts or operational time lags.
6) Low temperature, low humidity
environments.
The plastic may become brittle if coaxial
switch is exposed to a low temperature,
low humidity environment for long periods
of time.
6. Other handling precautions.
1) Coaxial switch’s on/off service life is
based on standard test conditions
(temperature: 15 to 35°C 59 to 95°F,
humidity: 25 to 75%) specified in JIS
C5442-1996. Life will depend on many
factors of your system: coil drive circuit,
type of load, switching intervals,
switching phase, ambient conditions, to
name a few.
2) Use coaxial switch within
specifications such as coil rating, contact
rating and on/off service life. If used
beyond limits, coaxial switch may
overheat, generate smoke or catch fire.
3) Be careful not to drop coaxial switch. If
accidentally dropped, carefully check its
appearance and characteristics before
use.
4) Be careful to wire coaxial switch
correctly. Otherwise, malfunction,
overheat, fire or other trouble may occur.
5) The latching type product is shipped in
the reset position. But jolts during
transport or impacts during installation
can move it to the set position. It is,
therefore, advisable to build a circuit in
which coaxial switch can be initialized
(set and reset) just after turning on the
power.
6) If coaxial switch stays on in a circuit for
many months or years at a time without
being activated, circuit design should be
reviewed so that the coaxial switch can
remain deenergized. A coil that receives
current all the time heats, which
degrades insulation earlier than
expected. A latching type is
recommended for such circuits.
7) For SMA connectors (SMA type only),
we recommend a torque of 0.90±0.1 N·m
for installation, which falls within the
prescribed torque of MIL-C-39012.
Please be aware that conditions might be
different depending on the connector
materials and how it interacts with
surrounding materials.
8) Please do not use silicon based
substances such as silicon rubber, silicon
oil, silicon coatings and silicon fillings, in
the vicinity of the coaxial switch. Doing so
may cause volatile silicon gas to form
which may lead to contact failure due to
the adherence of silicon on the contacts
when they open and close in this
atmosphere.
9) In order to ensure stable signal
communication on contact, it is
recommended that the monitoring of
contact signal should be started from
Min. 100 ms after coil rated voltage is
applied.
