PARAMETERS FUNCTION
Functional description
The working principle of inductive proximity switch
Inductive proximity switch mainly is to use the metal conductor and
the mutual inductance alternating electromagnetic field theory, can make
the magnetic field will produce eddy current attenuation of metal materials.
This will make the magnetic field energy attenuation and decreasing
amplitude,in the inductive proximity switch such changes will make the
corresponding output level flip (as shown in the right 1)
Induction zone
Oscillation circuit
Inductive proximity switch standard induction
By induction type material for Fe37 steel to define the induction area,
its thickness to 1 mm.(according to EN 60947-5-2) dimension is take
induction flour for the side length of the square or for three times the
diameter circle detection distance (either the head).
The correction coefficient of inductive proximity switch
Relative to the standard test, the detection distance of the provisions
in the specified measurement conditions, tend to reduce the detection
distance,the smaller the correction factor, the action of a particular material
the smaller distance, the attenuation coefficient depending on the shell,
especially the shielding materials will be change. For inductive proximity switch,
the electrical conductivity of the test material is the main parameters affecting
the attenuation coefficient. The following data shows the induction of different
objects, the induction distance attenuation coefficient,
Such as right as shown in table 1.
