Omron D4B-2111N Snap-action contact with certified direct opening operation certification Datasheet

Safety Limit Switch
D4B-@N
CSM_D4B-_N_DS_E_5_1
Snap-action contact with certified direct
opening operation certification .
Maintenance, seal, and resistance to
shock increased and direct opening
mechanism added.
Three-conduit switches and 2NC
switches are also available.
Note: Contact your sales representative for details on models
with safety standard 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).
• 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
selection of operation on only one
side (left or right)
or both sides without the use of
any tools.
Roller
Nylon rollers used for superior resistance to wear.
Seal Ring
Sealing properties improved by using a X ring and
bearing-free structure.
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.
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.
Conduit Opening
Models are available with a wide range of conduits.

Application Precaution
Changing the Operating Direction
Operating section
(on back of Head)
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 procedure
1. Remove the four Head set screws and remove the Head
from the Switch Box.
Head Cover
Operating
position
mark
(arrow)
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.
Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Limit Switches”.
Mounting
Precautions 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.
Use four M5 screws with washers to mount the standard model. Be
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 −0.05
−0.15 mm diameter studs, each of which has a maximum height
of 4.8 mm as shown below.

• 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 7.
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.
* Apply a tightening torque of 0.78 to 0.88 N·m to three-conduit
models.

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.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size.

• 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 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.
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 like the D4B-@@16N or D4B-@@17N,
the Switch may telegraph. To avoid telegraphing, take the following
