NOTES

1. 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 relay.

Please use the latching type for circuits

that are continually powered for long

periods of time.

2. Coil connection

When connecting coils, refer to the wiring

diagram to prevent mis-operation or

malfunction.

3. Connection of coil indicator and

washing conditions

1) The connection of coil indicator

terminal shall be done by soldering.

Soldering conditions

10sec (soldering time)

3sec (soldering time)

2) This product is not sealed type,

therefore washing is not allowed.

4. Usage, transport and storage

conditions

1) Ambient temperature, humidity, and

atmospheric pressure during usage,

transport, and storage of the relay:

(1) Temperature:

(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:

2) Condensation

Condensation forms when there is a

sudden change in temperature under high

temperature and high humidity conditions.

Condensation will cause deterioration of

the relay insulation.

3) Freezing

Condensation or other moisture may

freeze on the relay when the temperature

problems such as sticking of movable

parts or operational time lags.

4) Low temperature, low humidity

environments.

The plastic becomes brittle if the relay is

exposed to a low temperature, low

humidity environment for long periods of

time.

5) Low-temperature and low-humidity

atmosphere.

When exposed to low temperature and

low humidity for a long time, the relay’s

plastic casing may become breakable.

5. Other handling precautions.

1) The relay’s on/off service life is based

on standard test conditions (temperature:

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 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) The latching type relay 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 the relay can be initialized (set and

reset) just after turning on the power.

6) 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.

7) For SMA connectors, 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 relay. 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.
