Operation Key
• Use only the designated Operation Key. The Head has been
designed so that operation is not possible with a screwdriver or
other tools. Using anything other than the designated Operation
Key may damage the Switch or affect machine safety.
• Do not operate the Switch with anything other than the special
OMRON Operation Key, otherwise the Switch may break or the
safety of the system may not be maintained.
• Do not impose excessive force on the Operation Key while the Key
is inserted into the Switch or drop the Switch with the Operation
Key inserted. Doing either of these may deform the Key or break
the Switch.
Head Direction
• The rotation of the Switch head may be adjusted to any of the four
directions by loosening the head mounting screws at the four
corners of the head. Make sure that no foreign materials enter
through the head.
• Do not insert or remove the Operation Key with the Switch head
removed. Doing so may make it impossible to insert the Operation
Key.
Securing the Door
When the door is closed (with the Operation Key inserted), the
Operation Key may exceed the set zone because of, for example, the
door's own weight, machine vibration, or the door cushion rubber.
Secure the door with a stopper so that the Operation Key remains
within the set zone.

Wiring
Wiring
• When connecting with insulation tubes and M3.5 crimp terminals,
connect the terminals as shown in the following figure and wire
without overriding to the case and the cover. Adequate conductor
size is AWG 20 to AWG18 (0.5 to 0.75 mm
Prepare lead wires using the lengths given in the following
diagrams. If lead wires are too long, they will press against the
cover causing the cover to not close properly.

• Do not push the crimp terminal and the likes into the opening
between the parts to prevent the case from being broken and
deformed.
• Use terminals having the thickness of 0.5 mm or less to avoid the
contact between the terminal and the Switch case inside.

Pin No. (Terminal No.)
• Suitable socket is XS2F-D421 series (OMRON).
• Refer to the Connector Catalog for corresponding Socket pin
numbers and lead wire colors.
Socket Tightening (Models with Connectors)
• Turn the tightening screws on the Socket by hand and tighten them
until the gap between the Socket and Plug essentially disappears.
• Make sure that the Socket's connector is tightened securely,
otherwise the rated degree of protection (IP67) of the D4NS may
not be maintained, or the Socket connector may be loosened by
vibration.
Conduit Outlet
• Use a cable conforming to the diameter of the cable gland to be
used.
• When wiring, place the enclosed cap screw on unused conduit
outlets (for 2-Conduit Types) and tighten them to the suitable
tightening torque.
Cable Gland
• Use a commercially available cable gland.
• Use the cable gland with thread section of 9 mm long or less.
