17、g face, and specifies the classification and designation to be used for such switches. 2 General definitions 2.1 inductive proximity switch an inductive proximity switch is a device producing a high frequency electromagnetic field in a sensing zone and having an electric contactless output the outpu
18、t signal is determined by the pressure or the absence in the electromagnetic field of a metallic object of sufficient size 2.2 sensing face the sensing face is a flat surface of the proximity switch through which the high frequency electromagnetic field emerges NOTEThe sensing face is marked by the
19、manufacturer. 2.3 reference axis a reference axis is an axis perpendicular to the sensing face and passing through its centre 2.4 target a target is an object used for making comparative measurements of the operating distance, its characteristics are specified in the standard EN 50010 the target pla
20、ne shall be maintained parallel to the sensing face of the proximity switch 2.5 free zone The free zone is a volume around the proximity switch which shall be kept free from any material capable of affecting the characteristics of the proximity switch. 2.5.1 non-damping material a non-damping materi
21、al is a material which has a negligible influence on characteristics of a proximity switch 2.5.2 embedded in metal proximity switch a proximity switch is “embedded in metal” when any metallic piece can be put around, below and up to the sensing face plane, without influencing its characteristics 2.5
22、.3 not embedded in metal proximity switch a proximity switch is “not embedded in metal” if it is necessary to have a free zone around the sensing face in order to maintain its characteristics 3 Definitions of geometrical characteristics 3.1 operating distance s (see Annex) The operating distance is
23、the distance at which the target approaching the sensing face causes the output signal to change.

24、 conventional quantity used to designate the operating distance. It does not take into account either manufacturing tolerances or variations due to external conditions such as voltage and temperature 3.1.2 effective operating distance sr the effective operating distance is the operating distance of
