How to select photoelectric switch in packaging machinery

by admin

Chaoyi electronics tells you that different photoelectric switches are used in different occasions. For example, optical fiber photoelectric switches are often used on electromagnetic vibration feeders, diffuse reflection photoelectric switches are often used in the supply of packaging film of intermittent packaging machines, and slot photoelectric switches are often used in continuous high-speed packaging machines. So, how can we choose the right one for different industries? In addition to selecting the correct variety and model, we should also consider the factors of the manufacturer. At present, there are many manufacturers of photoelectric switches in China. The scale of enterprises varies greatly. Of course, the quality varies greatly, but it does not mean that the product quality of large enterprises is good. Generally speaking, direct purchase from enterprises has a great grasp of quality. Now, in order to expand market share, some enterprises have different prices for products of the same model, and the quality of their internal components varies greatly. Therefore, when purchasing, it is necessary to clarify the guarantee of service life, and generally it is more cost-effective to buy more expensive products. The infrared photoelectric switch commonly used in the current market uses the reflection principle of the object to the near-infrared beam, and the synchronous circuit senses the strength of the reflected light to detect the existence of the object. The photoelectric sensor first sends the infrared beam to or through the object, and the object or mirror reflects the infrared beam, The photoelectric sensor receives the reflected beam and judges the existence of the object according to the intensity of the beam. There are many kinds of infrared photoelectric switches. Generally speaking, there are several main types, such as mirror reflection photoelectric switch, diffuse reflection photoelectric switch, slot type, opposite reflection photoelectric switch, optical fiber type and so on. Photoelectric switches were first introduced from abroad, and the advantages of foreign brands make foreign goods occupy most of the market. At present, the quality of foreign brands is still higher, but domestic brands are catching up. For example, some Taiwan enterprises such as Taiwan yiphotoelectron hope to use foreign brands, but they are often troubled by fake and shoddy products. Therefore, it is recommended not to buy products with brand advantages at the counter. It is convenient to contact now. You can contact the brand manufacturer or office directly to avoid taking advantage of fake brands.
