Selecting inductive sensors
Flush mountable proximity switches can be installed with their sensing faces flush to the metal. The distance from opposing metal surfaces must be ≥ 3sn and the distance between two proximity switches (side-by-side) ≥ 2d.
Non-flush mountable proximity switches can be identified by their “caps”, since they have no metal housing surrounding the area of the sensing face. The sensing face must extend ≥ 2sn from the metallic installation medium. The distance from opposing metal surfaces must be ≥ 3sn and the distance between two adjacent proximity switches ≥ 3d.
Opposing installation of 2 sensors requires for all inductive proximity switches a minimum distance of ≥ 3d between the sensing face.
Normally Non- flush mountable sensors detecting distance is larger than flush mountable sensors.
