Nomenclature
Operation Key
The dedicated key prevents operational mistakes and forci-
bly separates the contacts.
Head
The head can be mounted in four directions. The Opera-
tion Key can be inserted in five directions including the
downward direction.
Cover
The cover, with a hinge on its lower part, can be opened
by removing the screw of the cover, which ensures ease
of maintenance and wiring.
Built-in Switch
Has a positive opening mechanism which forcibly separates
the NC contacts even if they are welded.
The built-in switch incorporates a pair each of NC contacts
and NO contacts or two pairs of NC contacts.
Conduit
Wide switch variations.
Pg13.5: 1-conduit, 2-conduit models
G1/2: 1-conduit, 2-conduit models
1/2-14NPT: 1-conduit models
Oil Seal
The plunger has an O ring. The switch casing ensures
IP65 (except the keyhole, which ensures IP00). Use the
D4DS in places where the keyhole is free from oil and
metal chips.
Note: The housing and head of the D4DS are made of synthetic resin. If high
mechanical durability is required, use the D4BS Safety Door Switch.

Precautions
CAUTION
Do not dismount the operation key from the door intentionally
and insert it to the switch with the door open. Machine may
start operating and injury or death may be caused.
Do not use metal connectors or conduits with this switch. Rigid
connectors and conduits may damage the switch. The broken
conduit hole may cause an electrical shock hazard.
Install the operation key so that it will not hit the operator when the
door is open.
If the D4DS is to be used as a switch in an emergency stop circuit or
in a safety circuit for preventing accidents resulting in injuries or
deaths,
use NC contacts with a forced release mechanism and set
the D4DS so that it will operate in positive opening mode. For safety ,
install the Switch and the Operation Key using one-way rotational
screws
or other similar means to prevent them from easily coming
off. Protect the D4DS with an appropriate cover and post a warning
sign near the D4DS in order to ensure the safety of the door .
To prevent the D4DS from damage due to circuit short-circuiting,
connect
a fuse with a breaking current 1.5 to 2 times larger than the
rated current of the D4DS in series to the D4DS.
If the D4DS is used under EN-approved conditions, use a gI or gG
10-A fuse approved by IEC269.
Mounting
Be sure to mount the D4DS with a stopper as shown in the following
illustration. Do not use the casing of the D4DS as a stopper . Be sure
to install the stopper so that the space “a” will be a maximum of
3 mm.
Stopper
Switch
Correct Use
Operating Environment
Do not use the D4DS in the following environments, otherwise the
D4DS may malfunction.
• Locations subject to significant temperature fluctuations
• Humid locations where there is a risk of condensation
• Locations subject to significant vibrations
•Locations subject to metal chips, oils, and chemicals inside a
protective
door
Operation Key
Be sure to use a special Operation Key only. Do not operate the
D4DS
with anything other than the special Operation Key , otherwise
the D4DS may break or the safety of the system may not be main -
tained.
Do
not impose excessive force on the Operation Key inserted into
the D4DS or drop the D4DS with the Operation Key inserted, other -
wise
the Operation Key may deform or break.
Excessive force
Drop
Secure the Operation Key with screws so that the Operation Key
cannot
be removed with ease.
Refer to Dimensions for the mounting dimensions of the Operation
Key and properly mount and the Operation Key correctly so that the
position and angle will be correct.
Make sure that the Operation Key can be inserted properly with a
tolerance
of ± 0.5 mm in the upward, downward, left, or right direc -
tion,
otherwise the D4DS may soon become damaged.

Securing the Door
When the door is closed (with the Operation Key inserted), the door
(or the Operation Key) may be pushed back across the set zone due
to the door ’ s weight, the door cushion rubber , etc. If load is applied to
the Operation Key , the door may fail to unlock. Secure the door with
hooks so that it will remain within in the set zone.
Set zone
(0.5 to 3 mm)
Operation Key
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.
When changing the head mounting direction, make sure that the
Operation
Key is in the head.
Make sure that no foreign materials penetrate through the mounting
holes of the head. Internal screws of the head must not be removed,
otherwise the internal parts of the head may be lost or deformed.
Wiring
Do not connect lead wires directly to the terminals. Be sure to con -
nect the lead wires through insulation tubes and crimp terminals.,
and tighten each terminal screw within an optimum torque range.
The lead wires must be an AWG20 to AWG14 type (i.e., 0.5 to
25 mm
2thick).

Conduit Opening
Tighten the connector to a torque of 1.8 to 2.2 N Sm (1.37 to
1.77 N S m if it is a 1/2-14NPT). Excessive tightening torque may
damage
the casing. In order to continue satisfying IP65, apply seal -
ing
tape to the connector conduit.
The diameter of the cable must be suited to the corresponding con -
nector.
Properly attach the provided conduit cap to the unused conduit
opening and securely tighten the cap screw within a torque range
between 1.27 and 1.67 N Sm when wiring the D4DS two-conduit
model.
