In order to keep the proximity sensor to work stably for long time, the ollowing regular examinations should be performed just like general control. 1.Check the installation position of detected object and proximityseensor if any deviation, loosening of deformation exiss. 2.Check the attached wires and connecting parts if any loosening, bad contact or wire breaking off exists. 3.Checkifthereisanymetallicpowderaccumulationornot. 4.Cherck if the temperature condition and surrounding environment condition are mormal or not. 5.Cherck if the detection distance is normal or not. 1mm Xmm() Detect at detection distance Xmm (front detector) whenchangethethicknessoftheassignedstandard detected object 1mm. X(mm) ()1 mm For more than 1mm thick ma- gnetic metal like iron, on the main, the detection distance will not chaneg. Current consumption of inductive proxi mity switch decreases proportional to the metal object distance. : Inductive proximity switch is composed of three parts: oscillator, switch circuit and magnified output circuit. The oscillator will generate an alternating electric field. When hemetal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object, resulting in attenuation of vibrati on and then stop. The changeof vibration and stop of oscillator is treated by begid stage magnified circuit and convertedto switching sign, triggering driving con-contact detection.
