Precautions

Refer to page 25 for information on general precautions. Be sure to read these precautions before using the Relay.

Correct Use

Long-term Continuously ON Contacts

Using the Relay in a circuit where the Relay will be ON continu-

ously for long periods (without switching) can lead to unstable

contacts because the heat generated by the coil itself will affect

the insulation, causing a film to develop on the contact surfaces.

We recommend using a latching relay (magnetic-holding relay) in

this kind of circuit. If a single-side stable model must be used in

this kind of circuit, we recommend using a fail-safe circuit design

that provides protection against contact failure or coil burnout.

Relay Handling

Use the Relay as soon as possible after opening the moisture-

proof package. If the Relay is left for a long time after opening the

moisture-proof package, the appearance may suffer and seal fail-

ure may occur after the solder mounting process. To store the

Relay after opening the moisture-proof package, place it into the

original package and sealed the package with adhesive tape.

When washing the product after soldering the Relay to a PCB,

use a water-based solvent or alcohol-based solvent, and keep the

solvent temperature to less than 40°C. Do not put the Relay in a

cold cleaning bath immediately after soldering.

Soldering

Soldering temperature: Approx. 250°C (260°C if the DWS method

is used)

Soldering time: Approx. 5 s max. (approx. 2 s for the first time and

approx. 3 s for the second time if the DWS method is used)

Be sure to adjust the level of the molten solder so that the solder

will not overflow onto the PCB.

Claw Securing Force During Automatic Mounting

During automatic insertion of Relays, make sure to set the secur-

ing force of each claw to the following so that the Relays charac-

teristics will be maintained.

Environmental Conditions During Operation, Storage, and

Transportation

Protect the Relay from direct sunlight and keep the Relay under

normal temperature, humidity, and pressure.

If the Relay is stored for a long time in an adverse environment

with high temperature, high humidity, organic gases, or sulfide

gases, sulfide or oxide films will form on the contact surfaces.

These films may result in unstable contact, contact problems, or

functional problems. Therefore, operate, store, or transport the

product under specified environmental conditions.

Latching Relay Mounting

Make sure that the vibration or shock that is generated from other

devices, such as relays in operation, on the same panel and

imposed on the Latching Relay does not exceed the rated value,

otherwise the Latching Relay that has been set may be reset or

vice versa. The Latching Relay is reset before shipping. If exces-

sive vibration or shock is imposed, however, the Latching Relay

may be set accidentally. Be sure to apply a reset signal before

use.

Maximum Allowable Voltage

The maximum allowable voltage of the coil can be obtained from

the coil temperature increase and the heat-resisting temperature

of coil insulating sheath material. (Exceeding the heat-resisting

temperature may result in burning or short-circuiting.) The maxi-

mum allowable voltage also involves important restrictions which

include the following:

• Must not cause thermal changes in or deterioration of the insu-

lating material.

• Must not cause damage to other control devices.

• Must not cause any harmful effect on people.

• Must not cause fire.

Therefore, be sure to use the maximum allowable voltage beyond

the value specified in the catalog.

As a rule, the rated voltage must be applied to the coil. A voltage

exceeding the rated value, however, can be applied to the coil

provided that the voltage is less than the maximum allowable volt-

age. It must be noted that continuous voltage application to the

coil will cause a coil temperature increase thus affecting charac-

teristics such as electrical life and resulting in the deterioration of

coil insulation.

Coating

The Relay mounted on the PCB may be coated or washed but do

not apply silicone coating or detergent containing silicone, other-

wise the silicone coating or detergent may remain on the surface

of the Relay.

PCB Mounting

If two or more Relays are closely mounted with the long sides of

the Relays facing each other and soldering is performed with

infrared radiation, the solder may not be properly exposed to the

infrared rays. Be sure to keep the proper distance between adja-

cent Relays as shown below.

Two or more Relays may be closely mounted with the short sides

of the Relays facing each other.
