Insert the Operational Unit from the front surface of the panel,

insert the Lock Fitting and the mounting nut from the terminal

side, then tighten the nut. Before tightening, check that the rubber

washer is present between the Operational Unit and the panel.

Align the Lock Fitting with the groove in the casing, then insert

the Lock Fitting so that its edge is located on the panel side.

For 25 mm-dia. holes, always use 25 mm-dia. Rings. (Since the

cutout dimensions are large, IP65 cannot be guaranteed unless

25-dia. Rings are used.)

Tighten the mounting nut at a torque of 0.98 to 1.96 N • m {10 to

20 kgf • cm}.

When using a Lock Ring, replace with the supplied Lock Fitting,

insert the projecting part into the lock slot, and then tighten the

mounting nut.

If outer surface treatment such as paint is applied to the panel,

the panel dimensions after outer surface treatment must meet the

specified panel dimensions.

J ENGRAVING

Engrave the characters on the surface on the Cap. Make sure

that the characters are aligned parallel to the imaginary line

connecting the two protruding portions to the left and right of the

Cap.

Use either of the following screwdrivers.

Flat-head

The characters must not be engraved deeper than 0.5 mm. Apply

an alcohol-based paint coating, such as melamine, alkyd, or

acrylic resin paint coating, to the engraved characters.

aligned parallel to the imaginary line connecting the two protruding

portions to the left and right of the Cap.

J WIRING

Wiring Round Crimp Terminals

Remove the cardboard.

Loosen the terminal screw from the Switch Unit until it completely

comes off the groove, insert a screwdriver as shown in the following

figure, then push up the washer in the direction indicated by the

arrow to temporarily secure it. Now, a round crimp terminal can be

connected. After inserting the terminal, tighten the screws to com-

plete wiring.

J ENGRAVING METHOD

Material: Acrylic

Engrave the characters directly on the matted side of the Snap-in

Legend Plate.

All A22/M22 Assemblies

To easily remove the Snap-in Legend Plate from the Legend

Plate Frame mounted to the panel, insert a Tool with a thin tip

into the space between the Snap-in Legend Plate and the

Legend Plate Frame.

The characters must be engraved no deeper than 0.5 mm.

Apply alcohol-based paint coating to the engraved characters.

If the Snap-in Legend Plate is transparent, engrave the

mirror-written characters on the back of the Snap-in Legend Plate

and apply paint coating to the characters. Then apply paint

coating of a different color to the remaining part of the Snap-in

Legend Plate.

J MOUNTING THREE-THROW SPACER

Press and secure the two protruding portions of the Three-throw

Spacer to the two indented portions of the inner side of the

control panel.

The Snap-in Legend Plate is easily removed by pressing the

Snap-in Legend Plate from the back of the Legend Plate Frame.

The Legend Plate Frame is made of acrylic resin, which is easily

damaged by shock. Be sure to handle the Legend Plate Frame

with care.

Precautions

!

Wiring

WARNING

After wiring the Switch, maintain an appropriate clearance and

Do not apply a voltage between the incandescent lamp and

the terminal that is greater than the rated voltage. If the incan-

descent lamp is broken, the Operational Units may pop out.

Always turn OFF the power and wait for 10 minutes before

replacing the incandescent lamp. If the lamp is replaced

immediately after the power is turned OFF, the remaining heat

may cause burns.

creepage distance.

When DC-specific LEDs are used, wire the Switch so that the X1

terminal is positive.

Terminal screws must be Phillips or slotted M3.5 screws with a

square washer.

The tightening torque is 1.08 to 1.27 N • m {11 to 13 kgf • cm}.

J CORRECT USE

Mounting

Always make sure that the power is turned OFF before mounting,

removing, or wiring the Switch, or performing maintenance.

Single wires, stranded wires, and crimp terminals can be

connected to the Switch.

Operating Environment

The IP65 model is designed with a protective structure so that it

will not sustain damage if it is subjected to water from any

direction to the front of the panel.

Do not tighten the mounting ring more than necessary using tools

such as pointed-nose pliers. Doing so will damage the mounting ring.

The tightening torque is 0.98 to 1.96 N • m {10 to 20 kgf • cm}.

The panel thickness is 1 to 5 mm.

All A22/M22 Assemblies

Using the Microload

Others

Insert a contact protection circuit, if necessary, to prevent the

reduction of life expectancy due to extreme wear on the contacts

caused by loads where inrush current occurs when the contact is

opened and closed.

The oil-resistant IP65 uses NBR rubber and is resistant to

general cutting oil and cooling oil. Some particular oils cannot be

used with the oil-resistant IP65, however, so contact your

OMRON representative for details.

The minimum applicable load is the N-level reference value. This

value indicates the malfunction reference level for the reliability

level of 60% (λ 60) (conforming to JIS C5003).

If the panel is to be finished with coating, etc., make sure that the

panel meets the specified dimensions after the coating.

Do not subject the Switch to extreme shock or vibration. Doing so

will cause malfunctions and damage to the Switch.

-- 4

The equation, λ 60 = 0.5 x 10 /time indicates that the estimated

malfunction rate is less than 1/2,000,000 with a reliability level of

60%.

Do not let sharp objects come into contact with the Switches that are

made of resin. Doing so will damage the Switches, causing

scratches on the outside of the Operational Units, and malfunction.

When handling the Switches, do not throw or drop them.
