How to choose a suitable magnetic connector?

　　A good magnetic connector will affect the function of the entire device, and a suitable electromagnetic connector will bring good results. How to choose a suitable electromagnetic connector?

　　1. Type of magnetic connector

　　The purpose is to be considered first, which will determine the type of industrial magnetic connector to be selected. Magnetic connectors will be used in places such as indoors, outdoors, and corrosive environments. Therefore, it is necessary to consider enhancing the airtightness of the aviation plug or adding a shielding shell outside the insulating body. The type of magnetic connector determines which terminal is used and the number of conductive terminals arranged.

　　2. Electrical requirements

　　When choosing, consider the electrical requirements of the product. The voltage and current requirements of the product, and whether the magnetic connector can be used in electrical applications, all need to be considered. In addition, other electrical conditions need to be considered, such as resistance, allowable resistance change, millivolt drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, VSWR (voltage standing wave ratio), plug-in Pull loss and EMI shielding efficiency.

　　3. Environmental requirements

　　Temperature, humidity, and other environmental factors depend on the location of the electromagnetic suction connector, so consider the location and the expected environment. As for the applicable period and information of other related storage conditions, the description of the environment should also include requirements for shock and vibration, including requirements for shipping, and requirements for production environmental conditions such as welding temperature and welding cycle duration. The area where the highest temperature occurs is around the convergent continuous current guided by the magnetic connector.

　　Fourth, mechanical performance requirements

　　What kind of volume and coverage area are effective, what is the allowable dimensional tolerance, how much the insertion and withdrawal force of the terminal, the durability of the magnetic connector (the frequency of mating), etc., should be considered when selecting the electromagnetic connector . For example, when using a printed circuit board, it is very important to confirm the tolerance of the circuit board, which is the critical value of the card edge magnetic connector and the feasibility of reaching the critical value. For low-power circuits, the plating and underlying materials must be specified in accordance with the signal standards and environmental levels.

　　Five, specifications

　　Magnetic connector manufacturers can choose about 25 testing institutions (specified specifications) as the source of all or part of the magnetic connector test specifications. It must be considered that the appropriate test specifications should be selected under specific application conditions, including internationally accepted conditions.
