RJ (ARJ)

ASCTB105E 201202-T

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 20 ms to set/reset the latching type

relay.

2. Coil connection

When connecting coils, refer to the wiring

diagram to prevent mis-operation or

malfunction.

3. External magnetic ﬁeld

Since RJ relays are highly sensitive

polarized relays, their characteristics will

be affected by a strong external magnetic

ﬁeld. Avoid using the relay under that

condition.

4. Cleaning

For automatic cleaning, the boiling

method is recommended. Avoid

ultrasonic cleaning which subjects the

relays to high frequency vibrations, which

may cause the contacts to stick.

It is recommended that alcoholic solvents

be used.

5. Tape and reel packing

1) Tape dimensions

2) Dimensions of plastic reel

6. Conditions for operation, transport

and storage conditions

1) Ambient temperature, humidity, and

atmospheric pressure during usage,

transport, and storage of the relay:

(1) Temperature:

–30 to +70°C –22 to +158°F

(However, tolerance range is –30 to

+60°C –22 to +140°F if package is

carried as is.)

(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

is lower than 0°C 32°F. This causes

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) Storage procedures for surface-mount

terminal types

Since the relay is very sensitive to

humidity, it is packed in humidity-free,

hermetically sealed packaging. When

storing the relay, be careful of the

following points:

(1) Be sure to use the relay immediately

after removing it from its sealed package.

(2) When storing the relay for long

periods of time after removing it from its

sealed package, we recommend using a

humidity-free bag with silica gel to

prevent subjecting the relay to humidity.

Furthermore, if the relay is solder

mounted when it has been subjected to

excessive humidity, cracks and leaks can

occur. Be sure to mount the relay under

the required mounting conditions.

7. Soldering

1) Surface-mount terminal

In case of automatic soldering, the

following conditions should be observed

(1) Position of measuring temperature

(2) IR (infrared reﬂow) soldering method

Temperature rise of relay itself may vary

according to the mounting level or the

heating method of reﬂow equipment.

Therefore, please set the temperature of

soldering portion of relay terminal and

the top surface of the relay case not to

exceed the above mentioned soldering

condition.

It is recommended to check the

temperature rise of each portion under

actual mounting condition before use.

2) Standard PC board terminal

Please meet the following conditions if

this relay is to be automatically soldered.

(1) Preheating: Max. 120°C 248°F

(terminal solder surface) for max. 120

seconds

(2) Soldering: Max. 260±5°C 500±9°F for

max. 6 seconds

The effect on the relay depends on the

actual substrate used. Please verify the

substrate to be used.

Moisture-proof packaging enables RJ

relay’s standard PCB type capable for

reﬂow soldering.

Please contact us in the case of reﬂow

soldering considerations.

3) Hand soldering

Please meet the following conditions if

this relay is to be soldered by hand.

(1) Wattage: 30 to 60 W

(2) Tip temperature/time: 280 to 300°C

536 to 572°F for max. 5 seconds

The effect on the relay depends on the

actual substrate used. Please verify the

substrate to be used.

4) Avoid high frequency cleaning since

this may adversely affect relay

characteristics. Use alcohol-based

cleaning solutions when cleaning relays.

(signal path and two connectors)

9. Others

1) The switching lifetime is deﬁned under

the standard test condition speciﬁed in

the JIS* C 5442-1996 standard

(temperature 15 to 35°C 59 to 95°F,

humidity 25 to 75%). 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.

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.

• High-frequency load-operating

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 HNO3 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) 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.

7) 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.

8) We recommend latching type when

using in applications which involve

lengthy duty cycles.
