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. 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.
Wiring
When DC-specific LEDs are used, wire the Switch so that the X1 ter-
minal is positive.
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 mm
Solid wire: 1.6 mm dia.
Naked Crimp Terminals
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
Contact failure may occur is 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% ( 60) (conforming to JIS C5003).
The equation,
function rate is less than 1/2,000,000 with a reliability level of 60%.

Insulating Sheaths
Cat. No. A119-E1-06
Do not apply a voltage exceeding the rated voltage across the incan-
descent lamp terminals.
The lamp may be destroyed and the operation unit may fly out.

LEDs
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.
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.
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 Pushbuttons, and malfunction.
When handling the Switches, do not throw or drop them.
