Safety Limit Switch
D4B-#N
• Snap-action or slow-action contact for
accurate switching with safe operation
via a direct opening mechanism with
metal deposition between mating con-
tacts.
• Two sets of contacts: one (NC) for safe-
ty category circuit and the other (NO)
for control circuit.
• Contacts opened by direct opening
mechanism (NC contacts only), thus
preventing faulty operation due to fac-
tors such as metal deposition.
• Wide standard operating temperature
range:
–40°C to 80°C (standard type).
• Safety of lever settings ensured using a
mechanism that engages a gear be-
tween the operating position indicator
plate and the lever.
• Equipped with a mechanism that indi-
cates the applicable operating zone, as
well as push-button switching to control
left and right motion.
• Conforms to EN (TÜV) standards cor-
responding to the CE marking.
• 3-conduit switches are available.
• Metric conduit types available.

a complete assembly or individually as replacement parts. (Replacement parts are not available as a switch box and head assembly or as a head
and lever assembly.)

Contact Form (EN50013)
Direct Opening Mechanism
1NO/1NC Contact (Snap-action)
If metal deposition between mating contacts occurs on the NC contact side, they can be pulled apart by the shearing force and tensile force gen-
erated when part B of the safety cam or plunger engages part A of the movable contact blade. When the safety cam or plunger is moved in the
direction of the arrow, the Limit Switch releases.

With roller lever models, the direction of the switch head can
be varied to any of the four directions by loosening the roller
lever switch screws at the four corners of the head.
The roller lever switch em-
ploys a system which allows
selection of operation on on-
ly one side (left or right)
or both sides without the
use of any tools.
Available in four different types of conduit threads:
Pg 13.5, G1/2 or 1/2-14NPT, M20
Grooves which engage the lever every 90∞are cut in the
operating position indicator plate to prevent the lever from
slipping against the rotary shaft.
An optimum overtravel (OT) value may be secured by
setting a desired OT value with a projection.
Shearing Force Contact Separating Mechanism
(NC Contact Section Only)
Should any abnormality occur in the contact area, the
contacts are positively pulled apart from each other by
shearing force.

G-256 Safety Sensors / Components
Precautions
If the D4B-#N is applied to a safety category circuit for prevention of
injury, use the D4B-#N model that has an NC contact equipped with
a direct opening mechanism, and make sure that the D4B-#N oper-
ates in the direct opening mode. Furthermore, secure the D4B-#N
with screws or equivalent parts that are tightened in a single direc-
tion so that the D4B-#N cannot be easily removed. Then provide a
protection cover for the D4B-#N and post a warning label near the
D4B-#N.
In order to protect the D4B-#N from damage due to short-circuiting,
connect a fuse breaking a current 1.5 to 2 times higher than the
rated current in parallel with the D4B-#N.
If an application satisfying EN standards is to employ the D4BL,
apply the 10-A gI or gG fuse approved by IEC269.
Do not apply the D4B-#N to the door without applying a stopper to
the door.
If the D4B-#N is used with the actuator normally pressed, the
D4B-#N may malfunction or may soon have reset failures. Be sure to
check and replace the D4B-#N regularly.
Correct Use
Operating Environment
The D4B-#N is for indoor use. The D4B-#N may malfunction if the
D4B-#N is used outdoors. Be sure to use a model with a lever-type
actuator for outdoor use instead.
Do not use the D4B-#N in the following locations:
•Locations subject to severe temperature changes
•Locations subject to high temperatures or condensation
•Locations subject to severe vibration
•Locations where the product may come in contact with metal dust,
oil, or chemicals
Tightening Torque
Note: Apply a tightening torque of 0.78 to 0.88 N·m to conduit models.
Mounting
Use four M5 screws with washers to mount the standard model. Be
sure to apply the proper torque to tighten each screw. The D4B-#N
can be mounted more securely by using the four screws plus two
5–0.05/–0.15-mm protruding parts, each of which has a maximum
height of 4.8 mm as shown below.
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. The lever can be set at any angle by attaching the operating
position indicator plate to the Switch so that this side will face the
lever. In this case, however, the D4B-#N will not be approved by
SUVA or BIA. Make sure that the lever engages with the operating
position indicator plate securely so that the lever will not slip.
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.

1 M3.5 terminal screw 0.59 to 0.78 N·m

CW, CCW or Two-way Operation
The head of Side Rotary Switches can be converted in seconds to
CW, CCW, or two-way operation. The conversion procedure follows.
Procedure
1. Dismount the head by loosening the four screws that secure it.
2. Turn over the head to set the desired operation (CW, CCW, or
both). The desired operation can be selected by setting the mode
selector knob shown in the figure. This knob is factory set to the
“CW + CCW” (two-way operation) position.
3. Set the CW hole on the head at the operation position mark
(arrow) for clockwise operation or set the CCW hole right at the
arrow for counterclockwise operation. In either case, be sure to
set the hole position exactly at the arrow point.
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.
Connector
Make sure that each connector is tightened within the specified
torque range. The casing may be damaged if the connector is tight-
ened excessively.
If the 1/2-14NPT is used, cover the cable and conduit end with seal-
ing tape in order to ensure IP67.
The Pg13.5 connector must be Nippon Flex’s ABS-08Pg13.5 or
ABS-12 Pg13.5.
Use OMRON’s SC-series connector which is suited to the cable in
diameter.
Properly attach the provided conduit cap to the unused conduit open-
ing 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 precautions.
1. Set the lever to operate in one direction. For details, see page G-
257, CW, CCW or Two-way Operation.
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.
