Proper Usage

1. Mutual interference

More than two proximity switches are shown in the figure below. When they are installed face to face or in parallel, the frequency interference is easy to cause misoperation. Pay attention to the distance between products when installing them (there are notes in the figure below).

Influence of surrounding metal

If there is metal around the proximity switch, it will lead to poor reset and other misoperation. In order to prevent misoperation caused by the surrounding metal, attention should be paid to the distance between the product and the metal during installation (there are notes in the figure below).

"Sn" in the table is the detection distance
