Note 1 :Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.
Note 2 :The maximum operation distance stands for the maximum distance for which the sensor can detect the standard sensing object.
The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient temperature drift and/or supply voltage fluctuation.
Note 3 :It is the leakage current when the output is in the OFF state.
Note 4 :The maximum load current varies depending on the ambient temperature.
Note 5 :When the cable is extended, the residual voltage becomes larger.
Note 6 :If using the sensor in an environment where cutting oil droplets splatter, the sensor may be deteriorated due to added substances in the oil.
Please check the resistivity of the sensor against the cutting oil you are using beforehand.
