Note: 1. Although the Switch casing resists dust, oil, and water, make sure that the keyhole on the head is free from dust, oil, water, and
chemical, or the D4DS may wear out, break, or malfunction.
2. Life expectancy values are calculated at an operating temperature of 5°C to 35°C, and an operating humidity of 40% to 70%.
Contact your OMRON sales representative for more detailed information on other operating environments.

Nomenclature
Head
The head can be mounted in four directions. The Opera-
tion Key can be inserted in five directions including the
downward direction.
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.
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.
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.
Operation Key
The dedicated key prevents operational mistakes and forci-
bly separates the 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
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.

Only the NC contacts have a positive opening function.
When metal deposition occurs, the contacts are separated
from each other by pushing in the plunger.
