First, in order to confirm the use of the environment before the submission, such as whether to detect metal objects, whether used to detect liquids, the detection of the object is magnetic, so as to choose a better magnetic proximity switch, because the magnetic proximity switch is divided into two types, one is inductance type, the other is capacitive type.
Second, confirm the type of drive power supply, DC or AC power.
Third, the use of state: often open or often closed.
Four, the intention type: has the cylinder, the square, the concave shape, the convex type and so on.
V, installation type: Closed or not shielded type.
Installation mode: Guided, inserted, linear, L-type.
Seven, detection frequency, that is, the number of objects detected per second.
