Precautions
!
WARNING
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.

Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
Current (mA)
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).
LEDs
The LED current-limiting resistor is built-in, so internal resistance
is not required.

below. If the soldering is not properly performed, the lead wires
will become detached, resulting in short-circuits.
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.
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.
If the panel is to be finished with coating, etc., make sure that the
panel meets the specified dimensions after the coating.
Use non-corrosive resin fluid as the flux.
Do not subject the Switch to extreme shock or vibration. Doing so
will cause malfunctions and damage to the Switch.
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.
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.
After wiring the Switch, maintain an appropriate clearance and
creepage distance.
When handling the Switches, do not throw or drop them.
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.
Do not allow the Switch
to drop and hit the
ground.
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 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.
Do not place or drop
heavy objects on the
Switch.
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).
