opening operation certification
.
Maintenance, seal, and resistance to
shock increased and direct opening
mechanism added.
Three-conduit switches and 2NC
switches are also available.
• Direct opening mechanism (NC contacts only) added to
enable opening contacts when faults occur, such as fused
contacts.
• Safety of lever settings ensured using a mechanism that
engages a gear between the operating position indicator plate
and the lever.
• Equipped with a mechanism that indicates the applicable
operating zone, as well as push-button switching to control left
and right motion.
• Head seal structure strengthened to improve seal properties
(TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).
• Wide standard operating temperature range:
–40 to 80°C (standard type).
• Models with gold-plated contacts added to the series to
enable handling microloads.
• Certified standards: UL, CSA, EN (TÜV), and CCC.
Be sure to read the “Safety Precautions” on page 14
and the “Precautions for All Safety Limit Switches” .

Structure and Nomenclature
Structure
Head
Can be connected in any of four directions (except for
Roller Plunger Models, which can be connected at either
of 2 directions that differ by 90°)
The roller lever switch employs a
system which allows
Roller
selection of operation on only one
side (left or right)
Nylon rollers used for superior resistance to wear.
or both sides without the use of
any tools.
Lever (Form Lock Structure)
The lever has an operating position indication plate
and grooves that mate every 90° to prevent slipping
between the rotary axis and lever.
Seal Ring
Sealing properties improved by using a X ring and
bearing-free structure.
The operating position indicator plate
Built-in Switch
Direct opening mechanism used for NC contact to
separate contact for faults, such as contact welding.
The heights of the NC and NO terminals are different
to enable easier wiring.

Operating procedure
The operating direction of the lever can be easily
changed without using any tools. It can be set to
clockwise operation (CW) or counterclockwise
(CCW) operation.
Use the procedure given at the right to change
the operating direction.
1. Remove the four Head set screws and remove the Head
from the Switch Box.

2. Turn the bottom of the Head toward you, press in the Head
Cover shown in the diagram at the left, and turn the Cover
clockwise or counterclockwise.
(arrow)
Note: The factory setting is for “CW.CCW.”
3. The “CW” setting is for clockwise operation and the “CCW”
setting is for counterclockwise operation. Set the Cover to
the desired position.
Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Limit Switches”.
Mounting
Precautions for Safe Use
Use four M5 screws with washers to mount the standard model. Be
• Do not use the Switch submerged in oil or water, or in locations
continuously subject to splashes of oil or water. Doing so may
result in oil or water entering the Switch interior. (The IP67 degree
of protection specification for the Switch refers to water penetration
while the Switch is submersed in water for a specified period of
time.)
• Always attach the cover after completing wiring and before using
the Switch. Also, do not turn ON the Switch with the cover open.
Doing so may result in electric shock.
sure to apply the proper torque to tighten each screw. The 3-conduit
models can be mounted more securely by using the four screws plus
two 5−0.105 mm diameter studs, each of which has a maximum height
of 4.8 mm as shown below.

Changes in Actuator Mounting Position
• To change the angle of the lever, loosen the Allen-head bolts on
the side of the lever.
• The operating position indicator plate * has protruding parts which
engage with the lever, thus allowing changes to the lever position
by 90°.
(5)
(2)
• The back of the operating position indicator plate * has no
protruding parts. If this plate is turned over and attached, any angle
within a 360° range can be set. Do not turn over the plate, however,
when using the D4B-@N as a switch with a certified direct opening
mechanism. For an SUVA- or BIA-certified application, make sure
that the lever engages with the operating position indicator plate
securely so that the lever will not slip.

Wiring
Conduit Opening
Do not connect the bare lead wires directly to the terminals but be
sure to connect each of them by using an insulation tube and M3.5
round crimp terminals and tighten each terminal screw within the
specified torque range.
• Make sure that each connector is tightened within the specified
torque range.
The casing may be damaged if the connector is tightened
excessively.
• If the 1/2-14NPT is used, cover the cable and conduit end with
sealing tape in order to ensure IP67.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size.
• The Pg13.5 connector must be Nippon Flex’s ABS-08 Pg13.5 or
ABS-12 Pg13.5.
• Use an OMRON SC-series Connector (sold separately) that is
suited to the cable in diameter.
• Properly attach the provided conduit cap to the unused conduit
opening and securely tighten the cap screw within the specified
torque when wiring the D4B-@N.
