WARNING Aluminum and Iron Cuttings This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use this product under ambient conditions that exceed the ratings. ● Design Influence of Surrounding Metal Normally aluminum or iron cuttings will not be detected even if they adhere to or accumulate on the sensing surface. Detection signals may be output for the following: If this occurs, remove the cuttings from the sensing surface. 1. Relationship between the Size of the Cutting (d) and the Size of the Sensing Surface (D) 2 Cuttings of the size d ≥ 3 D on the sensing surface * Cuttings of the size d* (Unit: mm) Model When mounting the Sensor within a metal panel, ensure that the clearances given in the following table are maintained. Failure to maintain these distances may cause deterioration in the performance of the Sensor.
