Safety Precautions
Be sure to read the precautions for All PushButton Switches in the website at:http://www.ia.omron.com/.
Indication and Meaning for Safe Use
Precautions
for Safe Use
Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.
Supplementary comments on what to do
or avoid doing, to use the product safely.
Caution
If the Operation Unit is separated from the Socket Unit, the
equipment will not stop, creating a hazardous condition.
Secure the lever on the Socket Unit by using the
A22Z-3380 Lock Plate so that the Operation Unit cannot be
easily separated from the Socket Unit.
(Refer to “Mounting the Lock Plate” at the below.)
• The LED current-limiting resistor is built-in, so internal resistance
is not required.
• If commercially available LEDs are used, select the ones that meet
the following conditions:
Base: BA9S/13
Overall length: 26 mm max.
Power consumption: 2.6 W max.
When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
• Mis-lighting of the LED
The LED lights with approx. 0.1 mA or less of micro-current. Take
a countermeasure like adding a resistor to prevent mis-lighting in
parallel to the LED.
The micro-current varies with the machine (leak current or stray
capacity between cables, etc.). Select resistance value and
allowable power consumption that meet the actual current.
In case of using 24 VAC/VDC, Direct lighting

Wiring
• 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.
• Single wires, stranded wires, and crimp terminals can be
connected to the Switch.
• Applicable Wiring Materials:
Twisted strands: 2 mm2 max.
Solid wire: 1.6 mm dia. max.
Naked Crimp Terminals
8 mm max.
R:10kΩ (1W)
Bleeder resistor

• Do not use a lamp that does not satisfy the rating.
Using the Microload
Contact failure may occur if a Switch designed for a standard load is
used to switch a microload. Use Switches within the application
ranges shown in the following graph. Even within the application
range, 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 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).
The equation, λ 60 = 0.5 x 10−6/time indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of 60%.

(When Using a Ring)
• The small size of the control panel is realized by conserving space
and changing the direction of the wiring.
• Since there is no looseness in the wiring, there is a reduction in
the maintenance efforts.
• A lock lever mechanism that can be easily operated is adopted.
• A maximum of up to six contact points can be combined together
in the contact-point configuration.
• Oil-resistant to IP65 (non-lighted models) / IP65 (lighted models) /

• Do not use the Switch/Indicator in locations where explosive or
flammable gases or liquid may be present or scattered. The
electric ark or the heat caused by switching contacts may cause a
fire or explosion.
• Do not use the Switch/Indicator in locations where toxic gases,
such as H2S, SO2, NH3, HNO3, and Cl2, may be present, or in
locations subject to high temperature or humidity. Doing so may
damage the Switch/Indicator due to contact failure or corrosion.
• Do not use the Switch/Indicator submersed in oil or water, or in
locations continuously subject to splashes of oil or water. Doing so
may result in oil or water entering and damaging the Switch/
Indicator.
• Do not use or keep the Switch/Indicator under the following
conditions:
• Subject to severe temperature changes.
• Subject to high humidity or condensation.
• Subject to severe vibration or shock.
• Where direct rays of the sun strike.
• Where sea breeze may be present.
• Make sure that a rubber washer is present between the Operation
Unit and the panel. Otherwise, the specifications of the protective
structure may not be satisfied.
• Do not apply excessive force to the Switch or wirings. Damage or
deformation of the Switch Block could cause an improper contact
or a loss of safety.
• Use an appropriate wiring and crimp terminals (hereinafter, called
ferrule terminals).
• Exercise caution to avoid wiring errors when connecting the
terminals.
• To prevent wiring materials from smoking or ignition, confirm wire
ratings and use the wiring materials given in the following table.
• When transition wiring is performed, make sure the switching
current inside the Switch and the current based on the transition
wiring is below the rated current of the Switch.
If a current value higher than the rated current flows, it could result
in emission of heat, or damage and deformation of the Switch,
which could cause fire and locking of the contact, and thus a loss
of safety.
• Do not perform wiring with power supplied to the Switch/Indicator.
Do not touch the terminals or other charged parts while power is
being supplied. Doing so may result in electric shock.
• Do not disassemble or modify the Switch/Indicator under any
circumstances.
• Doing so may prevent the Switch/Indicator from functioning to its
full capability. Do not drop the Switch/Indicator. Do not apply
pressure that may deform or alter the Switch/Indicator.
• The durability of the Switch varies considerably depending on the
switching conditions. Always test the Switch/Indicator under actual
working conditions before application and use the Switch/Indicator
only for the number of switching operations allowed.
• Do not allow the load voltage and current to exceed the rated
value. This may damage or burn out the Switch/Indicator.

Precautions for Correct Use
Wiring
A22E
• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
• Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force.
Doing so may cause the wire disconnection.
• Do not insert more than one wire into each terminal insertion hole.
• Do not mount A22N-P or A22NE-P Push-In Plus terminal switch
blocks on A22N screw terminal blocks. Doing so may result in
unsatisfactory performance.
• When mounting on a device with high airtightness, test operation
in advance. There is a risk that negative pressure will prevent the
push button from returning.
• Verify that the rubber boot is attached correctly.

A22NE-P
LED Lamps
A22E
• A current-limiting resistor is built in the LED lamp, so the
installation of an external resistance is not required.
• Lighting malfunction of the LED lamp
A micro-current of approximately 0.1 mA or less is sufficient to turn
on the LED lamps. Take a countermeasure like adding a resistor to
prevent mis-lighting in parallel to the LED lamp.
The micro-current varies with the machine (leak current or stray
capacity between cables, etc.). Select resistance value and
allowable power consumption that meet the actual current.

Precautions
for Safe Use
Precautions for Correct Use
Mounting
• Always make sure that the power is turned OFF before wiring the
Switch. Also, do not touch the terminals or other current-carrying
ports while power is being supplied. Electric shock may occur.
• 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.
• Recommended panel thickness: 1 to 5 mm.
• When mounting the caps after changing the LED or the caps,
tighten the caps at a tightening torque of 0.49 to 0.78 N·m.
• 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.
• The Switch is intended for indoor use only. Using the Switch
outdoor may cause it to fail.
A22NE-P
Operating Environment
Others
Do not allow the
Switch to drop and hit
the floor.
Do not operate the
Switch with hard or
sharp objects.
Hammer
Screwdriver
Common Note
Do not place or drop
heavy objects on the
Switch.
Common Accessories and Tools
• If the panel is to be coated, make sure that the panel meets the
specified dimensions after coating.
• Due to the structure of the Switch, severe shock or vibration may
cause malfunctions or damage to the Switch.
Also, most Switches are made from resin and will be damaged if
they come into contact with sharp objects. Particularly scratches
on the Operation Unit may create visual and operational
obtrusions.
Handle the Switches with care, and do not throw or drop them.
