D4B-@N
Wiring
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.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm²) in size.

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.

Conduit Opening
• 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 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.
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.

Dog
• When using a long lever model like the D4B-@@16N or D4B-@@17N,
the Switch may telegraph. To avoid telegraphing, take the following
precautions.
1. Set the lever to operate in one direction.
2. Modify the rear end of the dog to an angle of 15° to 30° as
shown below or to a secondary-degree curve.

3. Modify the circuit so as not to detect the wrong operating
signals.

Ordering Method
The D4B-@N uses a block mounting
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.
Note: For Switches with Roller Levers, do
not order just the Head and Lever, or
just the Switch Box and Lever.
