Oilproof heavy-duty vinyl cable: o3.4, 0.2 mm2 x 2 cores (Brown, Blue), 0.5 m Note 1) Refer to page 58 for reed switch common specifications. Note 2) Refer to page 58 for lead wire lengths. 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.

In a case where the wiring load is greater than 5 m. Use the contact protection box in any of the above listed situations. The contact point life may decrease. (Refer to page 58 for contact protection box.) 1.Confirm that the connector is appropriately tightened. If tightened insufficiently, the waterproof performance will deteriorate. 2.
