9. Measuring method of high frequency characteristics
(Impedance 50Ω)
Connect connectors 1 and 2 respectively to PORT 1 and
PORT 2. Perform calibration using the 3.5 mm calibration kit
(HP85052B).
After calibration, connect the D.U.T. board and measure.
However, connectors other than those for measurement should
be connected with a 50Ω termination resistor.
D.U.T. board
Dimensions (mm inch)
Material: Glass PTFE (double-sided, through hole PC board)
R-4737 (manufactured by our company)
Board thickness: t = 0.8 mm .031 inch
Copper plating thickness: 18 μm
Connector (SMA type)
Product name: 01K1808-00 (Waka Manufacturing Co., Ltd.)
Insertion loss compensation: The insertion loss of relay itself is
given by subtracting the insertion loss of calibration board.
10. Others
1) The switching lifetime is defined under the standard test
condition specified in the JIS* C 5442 standard (temperature
15 to 35°C 59 to 95°F, humidity 25 to 75%RH). Check this with
the real device as it is affected by coil driving circuit, load type,
activation frequency, activation phase, ambient conditions and
other factors. *JIS: Japanese Industrial Standards
Also, be especially careful of loads such as those listed below.
• When used for AC load-operating and the operating phase is
synchronous, rocking and fusing can easily occur due
to contact shifting.
• When high-frequency opening and closing of the relay is
performed with a load that causes arcs at the contacts, nitrogen
and oxygen in the air is fused by the arc energy and HNO
3 is
formed. This can corrode metal materials.
Three countermeasures for these are listed here.
(1) Incorporate an arc-extinguishing circuit.
(2) Lower the operating frequency
(3) Lower the ambient humidity
2) Use the relay within specifications such as coil rating, contact
rating and on/off service life. If used beyond limits, the relay may
overheat, generate smoke or catch fire.
3) Be careful not to drop the relay. If accidentally dropped,
carefully check its appearance and characteristics before use.
4) Be careful to wire the relay correctly. Otherwise, malfunction,
overheat, fire or other trouble may occur.
5) If a relay stays on in a circuit for many months or years at a
time without being activated, circuit design should be reviewed
so that the relay can remain non-excited. A coil that receives
current all the time heats, which degrades insulation earlier than
expected. A latching type relay is recommended for such
circuits.
6) To ensure accurate operation of the latching type amidst
surrounding temperature changes and other factors that might
affect the set and reset pulse times, we recommend a coil
impress set and reset pulse width of at least 30 ms at
the rated operation voltage.
7) The latching type relay is shipped in the reset position. But
jolts during transport or impacts during installation can change
the reset position. It is, therefore, advisable to build a circuit in
which the relay can be initialized (set and reset) just after turning
on the power.
8) If silicone materials (e.g., silicone rubbers, silicone oils,
silicone coating agents, silicone sealers) are used in the vicinity
of the relay, the gas emitted from the silicone may adhere to the
contacts of the relay during opening and closing and lead to
improper contact. If this is the case, use a material other than
silicone.
