Setting Distance Calculation Formula
The shape, size, and material of the sensing object all affect the sensing distance. For stable detection, please install within 70% of the sensing dzistance.
Influence of Mutual Interference and Surrounding Metal
■ Mutual Interference
As shown in the figure below, when two or more proximity switches are installed face-to-face or side-by-side, malfunctions may occur due to frequency interference. The installation spacing must meet the requirements below.
A = 320mm, B = 320mm
■ Influence of Surrounding Metal
If metal is present around the proximity switch, it may cause malfunctions such as poor resetting. To prevent malfunctions, the installation spacing must meet the requirements below.
d = 150mm, m = 80mm
