Precautions
Mounting
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 0.20 to 0.39 N m (3 to 5 kgf cm).
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
mm
below. If the soldering is not properly performed, the lead wires will
become detached, resulting in short-circuits.
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 protective structure 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.
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 operating part 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.

WARNING
The A16 allows both a general-purpose load (125 V at 5A, 250 V at 3
A) and a microload. If a general-purpose load is applied, however,
the microload area cannot be used. If the microload area is used
with a general-purpose 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% ( 60) (conforming to JIS C5003).
The equation,
malfunction 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.
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 represen-
tative for details.
If the panel is to be finished with coating, etc., make sure that the
panel meets the specified dimensions after the coating.
