How to introduce the description of Turck proximity switch

How to choose the German Turck Turck proximity switch? Clearly the following turck Turck proximity switch selection eight points, you can easily choose the most suitable proximity switch.
1. Select the proximity switch type based on the detected object. If the object to be inspected is the preferred inductive proximity switch for metal, if the object to be inspected is non-metallic such as wood, plastic, paper, water, etc. or a thinner metal, a capacitive proximity switch should be selected.
2. Proximity switch shape selection, which can be determined according to the position of the proximity switch installation. Generally, there are cylindrical proximity switches, square proximity switches, and ring proximity switches. If you choose a cylindrical shape, you should consider how big the diameter is needed. If you choose a square shape, you must also select the diameter of the detection surface.
3. The proximity distance of the proximity switch is generally short, and the detection distance of the proximity switch is relatively short, usually 1-50mm. The longer the detection distance, the larger the detection surface and the higher the price.
4. Proximity to the position of the sensing surface of the switch, usually with front end sensing, upper end sensing, and inner hole sensing;
5. The length of the proximity switch is selected. The standard connection cable length is 2 meters. If you need a longer cable, you should explain it to the manufacturer before ordering. However, it is easy to add the extension cable after approaching the switch. This will easily lead to instability of the proximity switch output signal.
6. Proximity switch output working voltage selection, usually DC DC24V or AC AC250V 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 selected;
8. Proximity switch connection mode selection, available in outlet type, connector type, pigtail type;
The TURCK proximity switch is the inductive switch that we usually call in life. It is a very advanced and tall switch. This kind of opening does not require mechanical transmission of power, and it is not cremation. It is a very safe switch. There are many types of switches, including inductive, capacitive, Hall, AC, and DC. Below we will have a certain understanding of all the proximity switch principles, and see that these proximity switches are not all the same.

The tT touch does not require any pressure to operate the switch, thereby driving DC power or providing control commands to a computer (PLC) device. The proximity switch is a type of switch type sensor (ie, non-contact switch), which has the characteristics of the stroke switch, and also has the performance of the sensor, stable and reliable performance, fast frequency response, long service life, strong anti-interference ability, etc. Waterproof, anti-corrosion and shockproof.
