Nomenclature
Head
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
only one side (left or right)
or both sides without the
use of any tools.
Operating Position Mark
(arrow)
Conduit Opening
Available in three different types of conduit threads:
Pg 13.5, G1/2 or 1/2-14NPT
Safety-Oriented Lever Setting
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.
Ground Terminal Screw
A ground terminal is provided to improve safety.
Equipped with Operating Position Indicator Plate
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.

JPOSITIVE CONTACT 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 generated 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.
1. When metal deposition occurs. 2. When contacts are being pulled
apart.
3. When contacts are
completely pulled apart.

Operating position
mark (arrow)
Head cover (Push and rotate)
Procedure
1. Remove 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.
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.
Precautions
If the D4B-jN is applied to an emergency stop circuit or safety
circuit for prevention of injury, use the D4B-jN model that has an
NC contact equipped with a force-separation mechanism, and
make sure that the D4B-jN operates in the positive mode. In
addition, secure the D4B-jN with screws that are tightened in a
single direction so that the D4B-jN cannot be easily removed.
Then provide a protection cover for the D4B-jN and post a
warning label near the D4B-jN.
In order to protect the D4B-jN 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-jN.
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-jN to the door without applying a stopper
to the door.
If the D4B-jN is used with the actuator normally pressed, the
D4B-jN may malfunction or may soon have reset failures. Be
sure to check and replace the D4B-jN regularly.
Tightening Torque
(3)
(4)
(1)
(5) (2)
Since loose screws may
cause a malfunction,
tighten each screw to the
appropriate torque.
Type Proper tightening torque
1Terminal screw (M3.5) 0.59 to 0.78 N Sm
2Cover-mounting screw
(see note) 1.18 to 1.37 N Sm
3Head-mounting screw 0.78 to 0.98 N Sm
4Switch-mounting screw
(M5) 4.90 to 5.88 N Sm
5Connector 1.77 to 2.16 N Sm
6Cap screw
(for three-conduit models) 1.27 to 1.67 N Sm
Note: Apply a tightening torque of 0.78 to 0.88 N Sm to conduit
models.

JCORRECT USE
Operating Environment
The D4B-jN is for indoor use. The D4B-jN may malfunction if
the D4B-jN is used outdoors. Be sure to use a model with a
lever-type actuator for outdoor use instead.
Do not use the D4B-jN in the following places:
•Places with radical temperature changes.
•Places with excessive humidity that may cause condensa-
tion.
•Places with excessive vibration.
•Places where metal dust, oil, or chemical may be sprayed to
the D4B-jN.
Mounting
Use four M5 screws with washers to mount the standard model. Be
sure to apply the propertorque to tighten each screw. The D4B-jN
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.

Protruding portions
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-jN 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.
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 solderless 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)insize.

Connector
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-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
opening and securely tighten the cap screw within the specified
torque when wiring the D4B-jN.
Actuator Load
The load for the actuator (roller) of the Switch must be imposed
on the actuator in the horizontal direction, or the actuator or the
rotating axis may be deformed or damaged.

When using a long lever model like the D4B-jj16N or
D4B-jj17N, the Switch may telegraph. To avoid telegraphing,
take the following precautions.
1. Set the lever to operate in one direction. (For details, see the
data sheet section: 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.
