9. Measuring method of high frequency characteristics

(Impedance 50

Ω)

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 50

Ω termination resistor.

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.

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

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.
