With a non-ferrous metal, the sensing range is obtained by multiplying with the correction coefficient specified below. Further, the sensing range also changes if the sensing object is smaller than the standard sensing object or if the sensing object is plated. Model No. Model No. INDUCTIVE PROXIMITY SENSORS MEASUREMENT SENSORS Refer to General precautions. Sensing range •As metal around the sensor may affect the sensing performance, pay attention to the following points.
