D4B-@N
Wiring
Conduit Opening
Do not connect the bare lead wires directly to the terminals but be
sure to connect each of them by using an insulation tube and M3.5
round crimp terminals and tighten each terminal screw within the
specified torque range.
• Make sure that each connector is tightened within the specified
torque range.
The casing may be damaged if the connector is tightened
excessively.
• If the 1/2-14NPT is used, cover the cable and conduit end with
sealing tape in order to ensure IP67.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm2) in size.
• The Pg13.5 connector must be Nippon Flex’s ABS-08 Pg13.5 or
ABS-12 Pg13.5.
• Use an OMRON SC-series Connector (sold separately) that is
suited to the cable in diameter.
• Properly attach the provided conduit cap to the unused conduit
opening and securely tighten the cap screw within the specified
torque when wiring the D4B-@N.

Make sure that all crimp terminals come into contact with the casing
or cover as shown below, otherwise the cover may not be mounted
properly or the D4B-@N may malfunction.
Others
• The load for the actuator (roller) of the Switch must be imposed on
the actuator in the horizontal direction, otherwise the actuator or
the rotating axis may be deformed or damaged.

Ordering Method
The D4B-@N uses a block mounting
Individual model numbers
method. Switches can be ordered either as
sets or as individual parts. If a set is
ordered, the Switch will be shipped with all
parts assembled.
