Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches/Indicators.
Precautions for Correct Use
• Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
• Do not tighten the mounting nut more than necessary using tools
such as pointed-nose pliers. Doing so will damage the mounting
nut.
The tightening torque is 0.29 to 0.49 N·m.
Wiring
• Solder terminals and quick-connect terminals (#110) are commonly
used for terminals.
• Be sure to use electrical wires that are a size appropriate for the
applied voltage and carry current (conductor size is 0.5 to 0.75
mm2). Perform soldering according to the conditions provided
below. If the soldering is not properly performed, the lead wires will
become detached, resulting in short-circuits.
1. Hand soldering: 350°C, within 3 s
2. Dip soldering: 350°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 touches 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.
Using the Microload
• 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 A16 allows both a standard load (125 V at 5A, 250 V at 3 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
opening and closing of the contact for a microload may become
unreliable.
• 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 × 10-6/operations indicates that the
estimated malfunction rate is less than 1/2,000,000 operations with
a reliability level of 60%.

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
representative for details.
• 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.
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 operating parts, and malfunction.
When handling the Switches, do not throw or drop them.
Do not allow the Switch
to drop and hit the
ground.
Do not place or drop
heavy objects on the
Switch.
Do not operate the Switch
with hard or sharp objects.
