Safety Limit Switch
D4B-@N
Robust safety limit switch with metal housing
Slow-action and snap-action contact with
certified direct opening operation
certification
• 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).
• Certified standards: UL, CSA, EN (TÜV), and CCC.

Application Precaution
Safety Precautions
Be sure to read the precautions for All Safety Limit Switches in the website at:http://www.ia.omron.com/.
Indication and Meaning for Safe Use
•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.
Appropriate Tightening Torque
Mounting
Use four M5 screws with washers to mount the standard model. Be
sure to apply the proper torque to tighten each screw.
Mounting Dimensions (M5)
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°.
•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.
*The operating position indicator plate: Refer to page 5.
Changes in Head Mounting Position
By removing the screws on the four corners of the head, the head can
be reset in any of four directions. Make sure that no foreign materials
will penetrate through the head.
Changing the Operating Direction
Switches with Roller Levers
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.
Operating section
(on back of Head) Operating procedure
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.
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.

Wiring
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.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size.
Make sure that all crimp terminals come into contact with the casing
or cover as shown below, otherwise the cover may not be mounted
properly or the D4B-@N may malfunction.
Conduit Opening
•Make sure that each connector is tightened within the specified
torque range.
The casing may be damaged if the connector is tightened
excessively.
•Use an OMRON SC-series Connector (sold separately) that is
suited to the cable in diameter.
Others
•The load for the actuator (roller) of the Switch must be imposed on
the actuator in the horizontal direction, otherwise the actuator or
the rotating axis may be deformed or damaged.
•
When using a long lever model, the D4B-

precautions.
1. Set the lever to operate in one direction.
2. Modify the rear end of the dog to an angle of 15° to 30° as
shown below or to a secondary-degree curve.
3. Modify the circuit so as not to detect the wrong operating
signals.

replacement thereof) the non-complying Product, (ii) repair the non-complying Product, or (iii) repay or credit Buyer an amount
equal to the purchase price of the non-complying Product; provided that in no event shall Omron be responsible for warranty,

combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself
is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine,
system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product
with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
practice to change part numbers when published ratings or features are changed, or when significant construction changes are
made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers
may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at
any time to confirm actual specifications of purchased Product.
