Safety Precautions
Refer to the Common Precautions for Pushbutton Switches on page 14.
Mounting
Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance. Electrical
shock or fire may result if the power is not turned OFF.
The tightening torque is 0.29 to 0.49 N·m.
Wiring
Be sure to use electrical wires that are a size appropriate for the
applied voltage and carry current. Perform soldering according to the
conditions given below. If the soldering is not properly performed,
abnormal heating may result, possibly resulting in fire.
1. Hand soldering: 30 W, within 5 s
2. Dip soldering: 240 C, within 3 s
Wait for one minute after soldering before exerting any external force
on the solder.
Use non-corrosive resin fluid as the flux.
Make sure that the electric cord is wired so that it does not touch the
Unit. If the electric cord will touch the Unit, then electric wires with a
heat resistance of 100 C min. must be used.
After wiring the Switch, maintain an appropriate clearance and
creepage distance.
Operating Environment
The IP65 model is designed with a degree of protection so that it will
not sustain damage if it is subjected to water from any direction to the
front of the panel.
Using the Microload
Insert a contact protection circuit, if necessary, to prevent the reduc-
tion 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 A165E-@U allows both a standard load (125 V at 1 A, 250 V at
0.5 A) and a microload. If a standard load is applied, however, the
microload area cannot be used. If the microload area is used with a
standard load, the contact surface will become rough, and the open-
ing and closing of the contact for a microload may become unreli-
able.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability level
of 60% ( 60) (conforming to JIS C5003).
The equation,
function rate is less than 1/2,000,000 with a reliability level of 60%.

LEDs
The LED current-limiting resistor is built-in, so internal resistance is
not required.
Operating Torque
Do not exceed an operating torque of 0.49 N·m in the direction of
rotation.
Do not pull the operating button or apply excessive force to any side
of the button. Otherwise it may be damaged.
Others
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 representa-
tive for details.
When painting or coating the panel, make sure that the specified
panel dimensions apply to the panel after painting or 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 cre-
ate visual and operational obtrusions. Handle the switches with care,
and do not throw or drop them.
