DL (AZD1)
Open and close the cover Mounting
For the adjustable roller arm, the cover
will not open and close since it contacts
the adjustable arm. Either extend the
arm fully or remove the arm, then open
or close the cover. Also, the same is true
of the adjustable rod types (AZD1007
and AZD1057).
1) When mounting, use washers (to pre-

0.49 to 0.69 N·m {5 to 7 kg·cm}.
2) To securely mount the switch, not only
fasten the main switch body only with

Adjustable Rod Length
To adjust the length of the adjustable
rod, slightly loosen the hex. nut that is
securing the rod and then change the
length. After making the change, tighten
the hex. nut keeping within a tightening
torque of 0.98 and 1.37 N·m. Over tight-
ening might damage the rod presser
plate.

1) This model uses silver terminals.
Therefore, if used at relatively low fre-
quencies for long periods of time, or if
used with very small loads, the oxidiza-
tion that forms on the contact surfaces
will not wear away and eventually cause
improper contact. For such applications,
use limit switches with gold/metal con-
tacts (e.g. VL limit switches) or ones
meant for small loads (e.g. HL limit
switches).

11) To protect against entry of foreign
matter from the outside, we recommend
sealing as much as possible using con-
duit connectors.
2) This switch is not designed for under-
water use. Do not use the unit under-
water.

3) Do not use the switch where it may
come in direct contact with organic sol-
vents, strong acids, strong alkaline liq-
uids or stream, or in atmospheres con-
taining flammable or corrosive gases.
4) For the arm type (roller arm type,
adjustable roller arm type), the arm can
only be set at 15° interval.
5) To improve reliability during actual
use, it is recommended that the opera-
tion be checked under installation condi-
tions.
6) If OT is too big, the life of limit switch
will be shortened switching friction. Use it
with enough margin of OT. 70% of OT
standard value will be good for use.
7) Do not use the switch in a silicon
atmosphere. Case should be taken
where organic silicon rubber, adhesive,
sealing material, oil, grease or lead wire
generates silicon.
12) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.

13) When used outdoors (in places
where there is exposure to direct sunlight
or rain such as in multistory car parks) or
in environments where ozone is generat-
ed, the influence of these environments
may cause deterioration of the rubber
material. Please consult us if you intend
to use a switch in environments such as
these.
14) Do not store in places where organic
gas might be generated or in places of
high dust content or high humidity.
15) Since the roller section of the roller
arm (50 mm dia. rubber roller type)
(AZD1003 and AZD1053) is heavy, the
contacts may reverse due to inertia of
the roller section which easily leads to
erroneous operation.
8) When wiring, do not connect the lead
wires directly to the terminals, but use the
crimp terminals and tighten them to a
torque of 0.39 to 0.59 N·m {4 to 6 kg·cm}.
9) After wiring, when attaching the cover
to switch body, be careful that the cover
to switch body, be careful that the cover
seal rubber is set normaly on it and tight-
en the screw to a torque of 0.20 to 0.39
N·m {2 to 4 kg·cm}. If tighten the screw
strongly, the thread is broken.
10) Safety mechanism is adopted which
secures positive break under such abnor-
mal conditions like contact welding,
spring break, etc. In case of using the
safety mechanism which breaks welded
N.C. contact, conform to the conditions
as shown below.
If there is a possibility of exposure to
shock, please make considerations for
safety, for example, by providing a
redundant circuit so that danger can be
avoided in the event that the contacts
reverse and cause erroneous operation.
(For the value below of adjustable rod,
the length of the rod shows the value
when length of rod is set at 26 mm same
as the roller arm. The value of adjustable
roller arm (50 dia. rubber roller) type
shows the value when arm length is set
at 40 mm.)
