(Shielded Model) Other Information Sensing Distance Part B Part A • The sensing distance depends on the sensing object size, material, and thickness. • If the sensing object has a thickness of less than 1 mm, the sensing distance will decrease. • In some cases, it may not be possible to detect stainless steel. Use the following graph and the Influence of Sensing Object Size and Material information in Engineering Data (Typical) as a reference. Note 1: If the thickness of the mounting bracket (t) exceeds 5 mm, be sure to install the Sensor so that ≥ 2, d (dia.) ≥ 45, and D ≥ 2.
