In some cases, visibility of the indicatorlight is not be possible if the output signal is less than 2.5 mA. However, there is noproblem in terms of contact output, if an output signal exceeds 1 mA or more.OUT (+)BrownReed switchReverse flowprevent diodeWeightUnit: gSwitch maincircuitLEDOUT (–)BlueAuto switch modelLead wire length(m)0.535D-A79W1153—Indicator light / Display methodOperatingrangeDimensionsUnit: mmDisplayRed Green RedOptimum operatingpositionNote) q In case the operation load is aninductive load.w In case the wiring load is greaterthan 5 m.Use the auto switch with a contact protectionbox in any of the above mentioned cases.(For details about the contact protection box,refer to page 27.)ø3.436.21.81411.5 Most sensitive position8ø3.2Indicator light157 423.533
