1. Select the proximity switch type according to the detected object. If the detection object is metal, the inductive proximity switch is preferred, and if the detection object is a non-metal such as wood, plastic, paper, water, etc., or a smaller and finer metal, a capacitive proximity switch should be selected.
2. The shape of the proximity switch is selected, which can be determined according to the position of the proximity switch installation, usually there are cylindrical proximity switches, square proximity switches, and annular proximity switches. If you choose a cylindrical shape, you should consider how large the diameter is needed, and if you choose a square type, you must also choose the diameter of the detection surface.
3. The sensing distance of the proximity switch is selected, generally speaking, the detection distance of the proximity switch is relatively short, the common one is 1-50mm. The longer the detection distance, the larger the detection surface and the higher the price.
4. The position of the sensing surface of the proximity switch is usually available for front-end induction, upper induction, and inner hole induction;
5. The cable length of the proximity switch is selected, and the standard configuration connection cable length is 2 meters. If you need a longer cable, you should explain to the manufacturer before ordering, but do not add an extension cable after the proximity switch, which will easily lead to the unstable output signal of the proximity switch.
6. The output working voltage of the proximity switch is selected, usually DC DC24V or AC AC250V are optional;
7. Proximity switch output mode selection, usually NPN-normally open, NPN-normally closed, PNP-normally open, PNP-normally closed, 2-wire normally open, 2-wire normally closed, DC 3-wire, DC 4-wire optional;
8. The proximity switch connection mode is selected, including outlet type, connector type, pig tail type;

Typical construction of a smart sensor
A sensor is an input device that receives a signal or stimulus and responds to it. Some sensors now integrate many sensing elements and readout circuitry into a single silicon chip, which then provides high accuracy and multiple functions. The new sensor has more functions, including user friendliness.

The cause of drift in temperature and humidity sensors – Blessing
1. The temperature and humidity sensor will drift during use, which is impossible to avoid.
2. The fundamental reason for the drift is that all pressure sensors are based on the elastic deformation of a kind of material, no matter how outstanding the elasticity of the raw material is, after each elastic recovery, there will always be ...

The role and classification of safety barriers
In electrical intrinsic safety explosion-proof, we generally divide the workplace into explosion-proof areas and non-explosion-proof areas. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the PLC placed in the electrical cabinet in the non-explosion-proof area through wires.
