The detection distance of the proximity switch and the action distance of the proximity switch refer to the spatial distance from the reference position (sensing surface of the proximity switch) to the detection surface measured when the proximity switch operates when the object to be detected moves in a certain way.

The rated action distance refers to the nominal value of the proximity switch action distance. When determining the detection distance of the proximity switch, the installation position of the proximity switch, the size and material of the object to be detected should be considered. When the same type of proximity switch detects objects of different materials, its action distance is different. For example, for Hall proximity switches, the operating distance is greatly affected by the magnetic field strength of the object being detected. The greater the magnetic field intensity of the object being measured, the easier it is for the Hall switch to operate.

For capacitive proximity switches, the larger the dielectric constant of an object, the easier it is to reach its nominal operating distance. It should be noted that when a capacitive proximity switch detects an object with a lower dielectric constant, the action distance can be adjusted by adjusting the potentiometer on the switch to increase the sensing sensitivity. Usually, the actual working distance of the proximity switch is set to 0.7 to 0.8 of the rated operating distance.
