    The advantage of waterproof RF coaxial connector
        The waterproof RF coaxial connector is usually working in the water.and they are waterproof.The power cable and net cable can be put in their internal.They can not only provide normal and reliable power,single transmission,but also can be waterproof ans dust-proof.     At present.The standard for waterproof is according to IP waterproof grade standard.You can see the number XX after IPXX to estimate the waterproof performance, The first number X is from zero to six.the maximum is 6,The second number is from zero to eight,so the maximum waterproofing grade is IP68.     With the development of technology,We use many application in our daily life.And the thing with electric are not very good at our safety.so It’s very important if the the application is waterproof.The waterproof connector has excellent sealing performance,reliable waterproof performance,For example,some device need to be fixed in the water or at the button of the water,Then if we use waterproof RF coaxial connectors,we don’t need to worry about the water especially the water contains many chemical substances destroy the devices.     The appearance of waterproof RF connector can be said to be a great blessing for us,It is widely used,We use waterproof RF coaxial connectors in many areas.Like in an industrial environment,LED lighting, urban outdoor lighting project, lighthouse, cruise ship, aviation, industrial equipment, cable, sprinkler and so on.which are all use waterproof connectors.Military field due to the application of strict requirements,Many waterproof connector are used, such as submarine connector, submarine-launched missile connector and so on.

    RF Connector expertise
        The basic properties of RF connectors can be divided into three categories: mechanical, electrical, and environmental.Another important mechanical property is the mechanical life of the connector.Mechanical Life is actually a durability indicator, they are referred to as mechanical operation in NATIONAL standard GB5095.It takes one insert and one pull out as a cycle, and judges whether the RF coaxial connector can normally complete its connecting function (such as contact resistance value) after the specified insert and pull cycle.     1.Mechanical property As far as connection function is concerned, plug and pull force is an important mechanical property.Plug and pull force is divided into insertion force and pull out force (pull out force is also called separation force), the two requirements are different.In the relevant standards, the maximum insertion force and minimum separation force are stipulated, which indicates that, from the perspective of use, the insertion force should be small (hence the structure of low insertion force LIF and no insertion force ZIF), while the separation force if too small will affect the reliability of contact.The plug and pull force and mechanical life of the connector are related to the coating quality (sliding friction coefficient) of the contact part and the dimension precision (alignment) of the contact part.      2.Electrical Properties The main electrical properties of connectors include contact resistance, insulation resistance and electrical strength.      (1) High quality electrical connectors should have low and stable contact resistance.The contact resistances of connectors vary from a few to tens of milliohms.      (2) Insulation resistance measures the insulation performance between the contacts of electrical connectors and between the contacts and the housing. Its order of magnitude varies from hundreds to thousands of megohm.      (3) The electrical strength, or voltage and dielectric resistance, is the ability to withstand the rated test voltage between the connector contacts or between the contacts and the housing.      Other electrical properties.Electromagnetic interference leakage attenuation is used to evaluate the electromagnetic interference shielding effect of the connector, which is generally tested within the range of 100MHz~10GHz frequency.For RF coaxial connectors, there are electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, voltage standing wave ratio (VSWR), etc.Due to the development of digital technology, in order to connect and transmit high-speed digital pulse signals, a new type of connector, namely high-speed signal connector, has appeared. Correspondingly, in terms of electrical performance, in addition to characteristic impedance, some new electrical indicators have appeared, such as Crosstalk, transmission delay, and delay.  &...

    MCX connector wholesale what factors will affect the offer
        It is estimated that in 2010, China's MCX RF connector market has reached 25.7 billion yuan. Now the market size of mcx connectors is growing at an average annual rate of 15%. What is the size of the MCX connector?     1, the impact of product structure on the quotation MCX connector wholesale is generally the company procurement, for product understanding, slightly poor, the product structure also has an impact on product quotation. MCX connector is a push-in connection structure, small size It is a convenient and fast RF coaxial connector with characteristic impedance of 50Ω and 75Ω. However, the appearance of the structure, the difficulty for manufacturers, such as elbows, heterosexual head.    2, the performance of the wholesale quotation has a large impact on the VSWR and insertion loss, mechanical parameters and other performance, different VSWR price difference is different, relatively speaking, the communication field is higher than the performance requirements of other fields in the application.     3, the impact of environmental requirements on the quotation Corrosion resistance, temperature tolerance, etc., ROHO can accept different environmental requirements, such as the current salt-mouse experiment  on the product is 720 hours. Of course, the requirements for different environments are naturally different.     As shown in Figure 4, the difference in materials affects the price of the quotation material directly affects the wholesale price of the MCX connector. The higher the material requirements, the higher the raw material cost of the manufacturer, and the better the material performance.     The above points can be used as a reference for the wholesale purchase of MCX connectors. ROHO has been focusing on RF connection, and its products are used in communications, radio frequency identification, automotive, medical, aviation, data storage, network signal transmission, military and other fields. If you still want to know some specific information about MCX connector wholesale, you can contact us to purchase small customer service, ready to answer your questions!
