D4BS
Safety-door Switch’s Special
Operation Key Directly Pulls
Apart the Contacts from Each
Other and Contributes to the
Safety of the Production Site
• Conforms to EN (TÜV) standards cor-
responding to the CE marking.
• Approved by UL, CSA, BIA, and SUVA
standards.
• The switch contact is opened by a di-
rect opening mechanism (NC contacts
only) when the protective cover is
opened. The EN-approved direct open-
ing mechanism is indicated by
on
the Switch.

2.
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 penetrate through the key hole on the head, otherwise Switch damage or malfunctioning may occur.
3.
The durability is for an ambient temperature of 5° C to 35° C and an ambient humidity of 40% to 70%. Contact your OMRON sales rep-
resentative for more detailed information on other operating environments.

Nomenclature
Operation Key
D4BS's exclusive-use Operation Key is provided
to assure accurate switching operation.
Set Zone Mark
A triangular Set Zone Mark makes it
easy to adjust the operating position
when inserting the Operation Key.
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.
Seal Ring (NBR)
Oil Seal (NBR)
The operation plunger employs an oil seal, with
which the switch box meets the requirements of
IP67 (the sealing capability of the Operation Key's
insertion mouth is IP00).
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.
Ground Terminal Screw
A ground terminal is provided to
improve safety. (Built into the
Unit.)
Seal Packing (NBR)
Conduit Opening
Available in four different types of conduit
threads: Pg 13.5, G1/2, or 1/2-14NPT, M20.
