direct opening mechanism is indicated by
on the Switch.
• Malfunctions and false operation prevented by special Operation Key.
• Wide temperature range specifications: −40 to 80°C.
• Degree of protection of the switch box: IP67 (EN60947-5-1).
• Series includes models with gold-plated contacts for handling the

the operating conditions and environment beforehand. Although the switch box is protected from dust, oil, or water penetration, do not use the
D4BS in places where dust, oil, water, or chemicals may enter through the key hole on the head, otherwise Switch damage or malfunctioning
may occur.
*2. The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. Contact your OMRON sales representative
for more detailed information on other operating environments.
*3. These figures are minimum requirements for safe operation.

Structure and Nomenclature
Structure
Head
The switch head is coated with
easy-to-see red paint. The mounting
direction of the switch head can be varied
to any of the four directions.
Operation Key
D4BS's exclusive-use Operation Key is provided
to assure accurate switching operation.
Seal Ring (NBR)
Set Zone Mark
A triangular Set Zone
Mark makes it easy to
adjust the operating
position when inserting
the Operation Key.
Oil Seal (NBR)
The operation plunger employs an oil
seal, with which the switch box meets
the requirements of IP67.
Built-in Switch
A shearing force contact separating mechanism (NC
contact) is employed, which positively pulls apart the
contacts from each other by using shearing force if
any abnormality such as contact welding should occur
in the contact area.
There is a difference in level between the NC and NO
terminal, which assures easy wiring.

Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches” .
Precautions for Safe Use
• Do not use the Switch submersed 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. (The IP67 degree of
protection of the Switch specifies the amount of water penetration
after the Switch is submerged in water for a certain 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.
Stopper Installation
Do not use a Switch as a stopper.
Be sure to install a stopper as shown in the following illustration when
mounting the Switch and adjust the stopper so that the Operation Key
is within the setting zone.
Do not subject the Switch to a shock that exceeds the Switch's shock
resistance of 1,000 m/s2.

model.
*2. Apply a torque of 4.90 to 5.88 N·m for an Allen-head bolt. For a
pan head screw, apply a torque of 2.35 to 2.75 N·m.

With a Three-conduit Model, the Switch can be mounted more
securely at four points rather than with just two mounting holes, i.e.,
by adding two studs at the bottom of the switch, each of which is 5 mm
maximum in height and 5 −0.05

Use spring washers to mount the Switch and Operation key, and

To ensure safety, use screws that cannot be easily removed or
another means to prevent the Switch and Operation Key from easily
being removed.

Operation Key
Wiring
Make sure that the Operation Key can be inserted properly with
a tolerance of ±0.5 mm in the upward, downward, left, or right
direction. Otherwise the D4BS may soon become damaged due to
misalignment.
Do not connect the lead wires directly to the terminals. Connect the
lead wires through insulation tubes and M3.5 round crimp terminals.
Tighten each terminal screw within the proper torque range.
The proper lead wire is AWG20 to AWG14 (0.5 to 2.5 mm2) in size.
Observe the specified insertion radius for the Operation Key and
insert it in a direction perpendicular to the key hole. Do not use the
D4BL operation key.

Wire using the methods shown below so that the crimp terminals are

Changes in Head Mounting Direction
By removing the screws on the four corners of the head, the head can
be reset in any of four directions. The head direction can be changed
with or without the Operation Key inserted in the head. Make sure that
no foreign materials enter through the head and that the head is
tightened securely within the proper torque range.

Conduit Opening
• Tighten the connector to a suitable torque.
• Excessive tightening torque may damage the casing.
• When using 1/2-14NPT conduits, apply sealing tape between the
connector and conduit opening to maintain the degree of protection
(IP67) of the Switch.
• If using a Pg13.5 conduit, use an ABS-08 Pg13.5 connector or an
ABS-12 Pg13.5 connector (manufactured by Nippon Flex).
• Use a connector (SC Series, sold separately) suitable for the outer
diameter of the cable.
• When wiring a 3-conduit model, securely tighten the cap screw
provided for unused conduit openings.
