Nomenclature
Head
With roller lever models, the direction of the switch head can
be varied to any of the four directions by loosening the roller
lever switch screws at the four corners of the head.
Safety-Oriented Lever Setting
Grooves which engage the lever every 90° are cut in the
operation indicator disk to prevent the lever from slipping
against the rotary shaft.
There are resin-lever and metal-lever types.
Cover
Easy to open and wire. (One mounting screw and opposite side is for hinge mounting.)
Built-in Switch
Wide switch variations.
Snap-action: 1NC/1NO
Slow-action: 1NC/1NO

Contact Material

1NC/1NO Contact (Snap-Action)
Conforms to EN60947-5-1 Positive Opening
If metal deposition between mating contacts occurs on the NC contact side, they can be pulled apart by the shearing force and tensile
force generated when part B of the safety cam or plunger engages part A of the movable contact blade. When the safety cam or plunger
is moved in the direction of the black arrow, the Limit Switch releases.

Precautions
!
CAUTION
Do not use metal connectors or conduits to wire the Limit
Switch, otherwise the conduit of the Limit Switch may break
and an electric shock may be received.
If the D4D-jN is applied to an emergency stop circuit or
safety circuit for prevention of injury, use a D4D-jN model
that has an NC contact equipped with a force-separation
mechanism, and make sure that the D4D-jN operates in the
positive mode. Furthermore, secure the D4D-jN with screws
or equivalent parts that are tightened in a single direction so
that the D4D-jN cannot be easily removed. Then provide a
protection cover for the D4D-jN and post a warning label
near the D4D-jN.
Be sure to connect a fuse with a breaking current 1.5 to 2
times larger than the rated current to the Limit Switch in parallel in order to protect the Limit Switch from damage due to
short-circuiting.
When using the Limit Switch for the EN ratings, use the gI or
gG 10-A fuse.

•
•
Mounting
Fasten the Switch with two M4 Allen-head bolts and washers. Provide a stud with a diameter of 4-0.05/-0.15 and a height of 4.8 mm
max. at two places as shown below so that the Switch is firmly fixed
at four points.

J CORRECT USE
Operating Environment

The Limit Switch is intended for indoor use only. Using the Limit

A loose screw may result in a malfunction. Be sure to tighten
each screw to the proper tightening torque as shown below.

Changing the Lever Angle
Processing the Conduit Opening
• To change the angle of the lever, loosen the lever mounting
Tighten the connector to a torque of 1.8 to 2.2 N S m (1.37 to
1.77 N S m if it is a 1/2-14NPT). Excessive tightening torque may
damage the casing. To satisfy IP65, apply sealing tape to the connector conduit.
The diameter of the cable must be suited to the corresponding connector.
When performing wiring, close conduit openings in any places that
will not be used using the cap screws provided as accessories.
Tighten the screws to the applicable torque.
screw. Then the lever can be set at any angle in 7.5°
increments.
• The length of a variable roller lever can be changed by
loosening the lever mounting screw.
• The lever mounting position may be inside out after removing
the lever mounting screw. Make sure that the lever will not
touch the Switch when the lever is mounted inside out.
Changing the Head Direction
Applying the Load
If the head direction has been changed, check the torque of each
screw and make sure that the screws are free of foreign substances,
and that each screw is tightened to the proper torque.
Applying a load to the switch actuator (roller) from a slanted
direction may deform or damage the actuator, or deform or
damage the rotary spindle, so make sure that the dog is straight.
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 solderless 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.
With rubber roller lever models, the rubber roller may turn white
with the passage of time, but this will not affect the quality of
operation.
