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 di󰀨erent. The nominal operating voltage should

be applied to the coil for more than 10 ms to set/reset the

latching type relay.

2) IR (infrared reow) soldering method

2. Coil connection

When connecting coils, refer to the wiring diagram to prevent

mis-operation or malfunction.

3. External magnetic eld

Since RA relays are highly sensitive polarized relays, their

characteristics will be a󰀨ected by a strong external magnetic

eld. 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.

GUIDELINES FOR MICROWAVE DEVICES USAGE

Precautions for Coil Input

For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.

https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp

Long term current carrying

A circuit that will be carrying a current continuously for long periods

without relay or microwave device switching operation. (circuits for

emergency lamps, alarm devices and error inspection that, for

example, revert only during malfunction and output warnings with form

B contacts) Continuous, long-term current to the coil will facilitate

deterioration of coil insulation and characteristics due to heating of the

coil itself.

For circuits such as these, please use a magnetic-hold type latching

relay. If you need to use a single stable relay, use a sealed type relay

that is not easily a󰀨ected by ambient conditions and make a failsafe

circuit design that considers the possibility of contact failure or

disconnection.

DC Coil operating power

Steady state 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, please check with the actual circuit since the electrical

characteristics may vary. The rated coil voltage should be applied to

the coil and the set/reset pulse time of latching type relay di󰀨ers for

each relays, please refer to the relay's individual specications.

Coil connection

When connecting coils of polarized relays, please check coil polarity

(+,-) at the internal connection diagram (Schematic). If any wrong

connection is made, it may cause unexpected malfunction, like

abnormal heat, re and so on, and circuit do not work. Avoid

impressing voltages to the set coil and reset coil at the same time.

Maximum allowable voltage and temperature rise

Proper usage requires that the rated coil voltage be impressed on the

coil. Note, however, that if a voltage greater than or equal to the

maximum continuous voltage is impressed on the coil, the coil may

burn or its layers short due to the temperature rise. Furthermore, do

not exceed the usable ambient temperature range listed in the catalog.

Maximum allowable voltage for coil

In addition to being a requirement for relay operation stability, the

maximum continuous impressed coil voltage is an important constraint

for the prevention of such problems as thermal deterioration or

deformity of the insulation material, or the occurrence of re hazards.

Temperature rise due to pulse voltage

When a pulse voltage with ON time of less than 2 minutes is used, the

coil temperature rise bares no relationship to the ON time. This varies

with the ratio of ON time to OFF time, and compared with continuous

current passage, it is rather small. The various relays are essentially

the same in this respect.

Operate voltage change due to coil temperature rise　

　(Hot start)

In DC relays, after continuous passage of current in the coil, if the

current is turned OFF, then immediately turned ON again, due to the

temperature rise in the coil, the pick-up voltage will become somewhat

higher. Also, it will be the same as using it in a higher temperature

atmosphere. The resistance/temperature relationship for copper wire

is about 0.4% for 1°C, and with this ratio the coil resistance increases.

That is, in order to operate of the relay, it is necessary that the voltage

be higher than the pick-up voltage and the pick-up voltage rises in

accordance with the increase in the resistance value. However, for

some polarized relays, this rate of change is considerably smaller.

Ambient Environment

Dew condensation

Condensation occurs when the ambient temperature drops suddenly

from a high temperature and humidity, or the relay and microwave

device is suddenly transferred from a low ambient temperature to a

high temperature and humidity. Condensation causes the failures like

insulation deterioration, wire disconnection and rust etc.

Panasonic Corporation does not guarantee the failures caused by

condensation.

The heat conduction by the equipment may accelerate the cooling of

device itself, and the condensation may occur.

Please conduct product evaluations in the worst condition of the actual

usage. (Special attention should be paid when high temperature

heating parts are close to the device. Also please consider the

condensation may occur inside of the device.)

Icing

Condensation or other moisture may freeze on relays when the

temperature become lower than 0°C.This icing causes the sticking of

movable portion, the operation delay and the contact conduction failure

etc. Panasonic Corporation does not guarantee the failures caused by

the icing.

The heat conduction by the equipment may accelerate the cooling of

relay itself and the icing may occur. Please conduct product

evaluations in the worst condition of the actual usage.

Low temperature and low humidity

The plastic becomes brittle if the switch is exposed to a low

temperature, low humidity environment for long periods of time.

High temperature and high humidity

Storage for extended periods of time (including transportation periods)

at high temperature or high humidity levels or in atmospheres with

organic gases or sulde gases may cause a sulde lm or oxide lm to

form on the surfaces of the contacts and/or it may interfere with the

functions. Check out the atmosphere in which the units are to be

stored and transported.

Package

In terms of the packing format used, make every e󰀨ort to keep the

e󰀨ects of moisture, organic gases and sulde gases to the absolute

minimum.

GUIDELINES FOR MICROWAVE DEVICES USAGE

Storage requirements

Since the SMD type is sensitive to humidity it is packaged with tightly

sealed anti-humidity packaging. However, when storing, please be

careful of the following.

1) Please use promptly once the anti-humidity pack is opened.(within

72 hours, Max. 30°C/70% R.H.). If left with the pack open, the relay

will absorb moisture which will cause thermal stress when reow

mounting and thus cause the case to expand. As a result, the seal

may break.

* For RE relays, after this bag is opened, the product must be used

within 24 hours.

2) If relays will not be used within 72 hours, please store relays in a

humidity controlled desiccator or in an anti-humidity bag to which

silica gel has been added.

* If the relay is to be soldered after it has been exposed to excessive

humidity atmosphere, cracks and leaks can occur. Be sure to mount

the relay under the required mounting conditions

* For RE relays, after this bag is opened, the product must be used

within 24 hours.

3) The following cautionary label is a󰀩xed to the anti-humidity pack.

Silicon

When a source of silicone substances (silicone rubber, silicone oil,

silicone coating materials and silicone lling materials etc.) is used

around the relay, the silicone gas (low molecular siloxane etc.) may be

produced.

This silicone gas may penetrate into the inside of the relay. When the

relay is kept and used in this condition, silicone compound may adhere

to the relay contacts which may cause the contact failure. Do not use

any sources of silicone gas around the relay (Including plastic seal

types).

NOx Generation

When relay is used in an atmosphere high in humidity to switch a load

which easily produces an arc, the NOx created by the arc and the

water absorbed from outside the relay combine to produce nitric acid.

This corrodes the internal metal parts and adversely a󰀨ects operation.

Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use

at high humidity is unavoidable, please contact our sales

representative.

Others

Cleaning

1) Although the environmentally sealed type relay (plastic sealed type,

etc.) can be cleaned, avoid immersing the relay into cold liquid (such

as cleaning solvent) immediately after soldering. Doing so may

deteriorate the sealing performance.

2) Surface mount terminal type relay is sealed type and it can be

cleaned by immersion. Use pure water or alcohol-based cleaning

solvent.

3) Cleaning with the boiling method is recommended (The temperature

of cleaning liquid should be 40°C or lower).

Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may

cause breaks in the coil or slight sticking of the contacts due to the

ultrasonic energy.

Other handling precautions

・Expected switching life is dened under the standard test conditions

(temperature 15 to 35°C, humidity: 25 to 75%) specied in JIS C

5442.

Expected switching life is depend on usage conditions; coil driving

circuit, load type, activation frequency, activation phase, ambient

conditions and other factors. Please check relays and microwave

devices on the actual circuit.

Also, pay special attention 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.

・Frequent switching under load condition

When high frequently switched under load condition that can cause

arc at the contacts, nitrogen and oxygen in the air is fused by the

arc energy and HNO3 is formed. This can corrode metal materials.

Countermeasures for these are.

1. Incorporate an arc-extinguishing circuit.

2. Lower the operating frequency

3. Lower the ambient humidity

・When used for ‘‘Dry switching’’ without load current, please contact

our sales representative.

・Please avoid relays to be used outside of the specication ranges

such as the coil rating, contact rating and switching life that may

cause abnormal heating, smoke, and re.

・In case relays and microwave devices are dropped, please do not

use.

Please refer to "the latest product specications"

when designing your product.
