Note 1) Refer to page 29 for reed switch common specifications.
Note 2) Refer to page 29 for lead wire lengths.
Note 3) In less than 5 mA condition, the indicating light visibility becomes low, and it may be
unreadable in less than 2.5 mA. However, as long as the contact ouput is over a 1 mA
condition, there will be no problem.

Note) 1. In the case operation load is an
inductive load.
2. In the case the wiring length to load is
more than 5 m.
3. In the case the load voltage is 100 VAC.
A contact protection box should be used if any of
the above conditions is applicable. (For detailed
information about the contact protection box,
please refer to page 29.)
Do not use anything other than the mount-
ing screws attached to the auto switch
body to secure the switch. If screws other
than those specified are used, it may
cause the switch to be damaged.
