DL (AZD1)
Open and close the cover Mounting
For the adjustable roller arm type, 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 variable rod types
(AZD1007 and AZD1057).
1) When mounting, use washers (to pre-

0.49ꢀtoꢀ0.69ꢀN•mꢀ{5ꢀtoꢀ7ꢀkg•cm}.
2) To securely mount the switch, not only
fasten the main switch body only with

11) To protect against entry of foreign
matter from the outside, we recommend
sealing as much as possible using con-
duit connectors.
12) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
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).

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.

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.

to the conditions as shown below.
(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.)
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.

generates silicon.
