Note: 1. The above values are initial values.
2. Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity.
Doing so may result in roughening of the contact surface and contact reliability may be lost.
*1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for
the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the
[email protected] in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. Otherwise, accelerated
wear, Switch damage or malfunctioning may occur.
*2. The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
*3. Do not pass the 3 A, 250 VAC load through more than 2 circuits.
*4. This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.

Structure and Nomenclature
Structure
Safety-oriented Lever Setting (Form lock mechanism)
Grooves which engage the lever are cut in the lever and
rotary shaft to prevent the lever from slipping against the
rotary shaft. The actuator locks (self-holding) when it moves
to the lock position.
Head
The direction of the Switch Head can be
adjusted to any of the four directions, except for
Switches with Roller Plungers, which can be
adjusted to either of two directions differing by
90°C.
Reset Head (Blue)
The direction of the reset head can be adjusted to any of
the four directions.
Conduit
A wide variety of conduits is available.
Built-in Switch
The built-in switch has a direct opening mechanism that
forcibly separates the NC contact even when there is
contact deposit.
Size
Cover
The cover, with a hinge on its lower part, can be opened
by removing the screw of the cover, which ensures ease
of maintenance and wiring.

Safety Precautions
● Be sure to read the precautions for all [email protected] models in the website at: http://www.ia.omron.com/.
!CAUTION
Switch Mounting
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
Precautions for Safe Use
• Do not use the Switch submerged in oil or water, or in locations
continuously subject to splashes of oil or water. Doing so may
result in oil or water entering the Switch interior. (The IP67 degree
of protection specification for the Switch refers to water penetration
while the Switch is submersed in water for a specified period of
time.)
• Always attach the cover after completing wiring and before using
the Switch. Also, do not turn ON the Switch with the cover open.
Doing so may result in electric shock.
• Do not switch circuits for two or more standard loads (250 VAC,
3 A). Doing so may adversely affect insulation performance.
• Make sure that the actuator is pushed into the lock position. Not
doing so may result in the actuator becoming unlocked, causing an
accident.
• Always reset the Switch manually. Not doing so may result in
damage to the reset function.
• Mount the Switch using M4 screws and spring washers and tighten
the screws to the specified torque.
• For safety, use screws that cannot be easily removed, or use an
equivalent measure to ensure that the Switch is secure.
• As shown below, two studs with a maximum height of 4.8 mm and
a diameter of 4 −0.05
−0.15 mm can be provided, the studs inserted into the
holes on the bottom of the Switch, and the Switch secured at four
locations to increase the mounting strength.

Precautions for Correct Use
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The contact
surfaces will become rough once they have been used and contact
reliability for smaller loads may be reduced.

Tighten each of the screws to the specified torque. Loose screws may
result in malfunction of the Switch within a short time.

By removing the four screws of the head, the mounting direction of
the head can be changed. The head can be mounted in four
directions.
Be sure that no foreign material will enter the head during a change
in direction.

Changing the Lever
3
The lever mounting screws can be used to set the lever position to
any position in a 360° angle at 7.5° increments. Grooves are incised
on the lever and rotary shaft that engage to prevent the lever from
slipping against the rotary shaft. The screws on adjustable roller lever
models can also loosened to change the length of the lever.
Remove the screws from the front of the lever before mounting the
lever in reverse (front/back), and set the level so that operation will be
completed before exceeding a range of 180° on the horizontal.

Contact Arrangement
• When connecting to the terminals via insulating tube and M3.5
crimp terminals, arrange the crimp terminals as shown below so
that they do not rise up onto the case or the cover.
Applicable lead wire size: AWG20 to AWG18 (0.5 to 0.75 mm2).
Use lead wires of an appropriate length, as shown below. Not
doing so may result in excess length causing the cover to rise and
not fit properly.

• Do not push crimp terminals into gaps in the case interior. Doing so
may cause damage or deformation of the case.
• Use crimp terminals not more than 0.5 mm in thickness. Otherwise,
they will interfere with other components inside the case.
[Reference] The crimp terminals shown below are not more than
0.5 mm thick.

• Refer to the Connector Catalog for details on socket pin numbers
and lead wire colors.
Socket Tightening (Connector Type)
• Turn the socket connector screws by hand and tighten until no
space remains between the socket and the plug.
• Make sure that the socket connector is tightened securely.
Otherwise, the rated degree of protection (IP67) may not be
maintained and vibration may loosen the socket connector.

Use connectors with screws not exceeding 9 mm, otherwise the
screws will protrude into the case interior, interfering with other

The connectors listed in the following table have connectors with
thread sections not exceeding 9 mm.

packing is sold separately.
• LAPP is a German manufacturer.
Others
• When attaching a cover, be sure that the seal rubber is in place and
that there is no foreign material present. If the cover is attached
with the seal rubber out of place or if foreign material is stuck to the
rubber, a proper seal will not be obtained.
• Do not use any screws to connect the cover other than the
specified ones. The seal characteristics may be reduced.
• With rubber roller lever models, the rubber roller may turn white
over time, but this will not affect the quality of operation.
• Use the following recommended countermeasures to prevent
telegraphing when using adjustable or long levers.
1. Make the rear edge of the dog smooth with an angle of 15° to
30° or make it in the shape of a quadratic curve.
2. Design the circuit so that no error signal will be generated.
