Note: 1.

2.
Once a contact has been used to switch a standard load, it cannot be used for a load of a smaller capacity.
Doing so may result in roughening of the contact surface and contact reliability may be lost.
*1.
The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for
the operating conditions and environment beforehand. Although the switch box is protected from dust or water penetration, do not use the
D4N-@R in places where foreign material such as dust, dirt, oil, water, or chemicals may penetrate through the head. Otherwise, accelerated
wear, Switch damage or malfunctioning may occur.
*2.
The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. For more details, consult your
OMRON representative.
*3.
Do not pass the 3 A, 250 VAC load through more than 2 circuits.
*4.
This value will vary with the switching frequency, environment, and reliability level. Confirm that correct operation is possible with the actual
load beforehand.

Structure and Nomenclature
Structure
Safety-oriented Lever Setting (Form lock mechanism)
Grooves
which
engage the lever are cut in the lever and
rotary shaft to prevent the lever from slipping against the
rotary shaft. The actuator locks (self-holding)
when
it moves
to the lock position.
Reset Head (Blue)
The direction of the reset head can
be
adjusted to any of
the four directions.
Head
The direction of the Switch Head can
be
adjusted to any of the four directions, except for
Switches
with
Roller Plungers,
which
can
be
adjusted to either of two directions differing
by
90°C.
Conduit
A
wide variety
of conduits is available.
Built-in Switch
The
built-in
switch has a direct opening mechanism that
forcibly separates the
NC
contact even
when
there is
contact deposit.
Cover
The cover,
with
a hinge on its lower part, can
be
opened
by
removing the screw of the cover,
which
ensures ease
of maintenance and
wiring.
