The installation conditions provide information about optimal installation of the sensors in the application without being restricted in their specified function (i.e., their operating distance). Due to the given installation conditions, a functional range must always be assumed. There is a connection between installation and operating distance.
Cylindrical magnetic field sensors can be flush or nonflush mounted in all non-magnetizable materials and metals without affecting the operating distance.
The operating distance sn depends on the type of damping magnet used. If the magnet has a unipolar alignment (north or south pole of the magnet points toward the sensor), a central sensing range of the sensor occurs with lateral side humps. These side humps are responsible for ensuring that a certain minimum distance between the sensor and the magnet is maintained for clear switching characteristics.

Arrangement Options for the Damping Magnets
In principle, this arrangement combination allows the damping magnet to be inserted flush into a carrier material or attached so that it is nonflush. It does not matter whether the north or south pole of the magnet points toward the sensor. It is important to note:

Cubic sensors also have installation conditions for flush and nonflush mount. These are specific to the product series and are available as installation information in the technical data for the selected sensor.
