■ Recommended Soldering Method

Temperature indicates the surface temperature of the PCBs.

IRS Method (for surface mounting terminal models)

(1) IRS Method (Mounting Solder: Lead)

(2) IRS Method (Mounting Solder: Lead-free)

• The thickness of cream solder to be applied should be within a range between 150 and 200

μm on OMRON’s recommended PCB pattern.

• In order to perform correct soldering, it is recommended that the correct soldering conditions be maintained as shown below on the left side.

Visually check that the Relay is properly soldered.

Precautions

■ Correct Use

Handling

Do not unpack the relay until mounting it.

Soldering

Solder: JIS Z3282, H63A or equivalent

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 make a molten solder level adjustment so that the solder

will not overflow on the PCB.

Claw Securing Force During Automatic

Mounting

During automatic insertion of Relays, make sure to set the securing

force of each claw to the following so that the Relays characteristics

will be maintained.

Environmental Conditions During Operation,

Storage, and Transportation

It is best to keep the relay in its packaging in a controlled environ-

ment until it is ready for mounting.

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

high temperature, high humidity, organic gases, or sulfide gases, sul-

fide 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 excessive vibration or

shock is imposed, however, the Latching Relay may be set acciden-

tally. 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 tempera-

ture may result in burning or short-circuiting.) The maximum allow-

able voltage also involves important restrictions which include the

following:
