Note 1) Operating load is an induction load.
Note 2) Wiring to the load is 5 m or longer.
Note 3) Load voltage is 100 VAC.
Use the contact protection box in any of the
above listed situations. The contact point life may
decrease. (Refer to page 12-13-5 for contact
protection box.)
1. Fix the switch with appropriate screw
installed on the switch body. If using other
screws, switch may be damaged.

Note 1) Regarding the common specifications of the reed switches, refer to page 12-13-5.
Note 2) Regarding the lead wire length, refer to page 12-13-5.
Note 3)
Under 5 mA, the strength of the indicator light is poor. In some cases, visibility of the indicator
light will not be possible where the output signal is less than 2.5 mA. However, there is no
problem in terms of contact output, when an output signal exceeds 1 mA or more.
