1. Confirm that the connector is appropriately

tightened. If tightened insufficiently, the
waterproof performance will deteriorate.

2. Refer to Best Pneumatics Vol. 6/7/8/9/10

Note 1) Operating load is an induction load.
Note 2) Wiring to the load is 5 m or longer.
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.)

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) Lead wire with connector may be shipped with switch.
Note 4) 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.
