How to choose a magnetic connector?vintage thimbles(图1)

  Today, I will introduce to you how to buy magnetic connectors? We know that the operation of a magnetic connector will affect the function of the entire device, and a suitable electromagnetic connector can bring twice the result with half the effort. So, how to choose a suitable electromagnetic connector? Next we will take a look together.

  1. Magnetic connector type 

  What to connect, where to use these issues are the first considerations, which determines the type of industrial magnetic connector selected. The location where the magnetic connector is used (indoor, outdoor, corrosive environment, etc.) will affect whether to enhance the airtightness of the aviation plug or add a shielding shell outside the insulating body. The type of magnetic connector determines which terminal  (Termina) is used, and how many conductive terminals should be arranged. Of course, this also involves some reference in terminal technology.

  2. Electrical requirements

  When choosing an electromagnetic connector, the electrical requirements of the product must be considered. What are the voltage and current requirements of the product, and whether the magnetic connector can be used in such electrical applications? These issues about electrical requirements need to be considered. In addition, we also need to consider some other electrical conditions: resistance, allowable resistance change, millivolt drop, larger current value, larger voltage value, inrush current value, characteristic impedance, VSWR (voltage standing wave ratio) , Insertion loss and EMI shielding efficiency.

  3. Environmental requirements

  Temperature, humidity, and other environmental conditions are determined by the location of the electromagnetic connector, so the location and the expected environment should be considered. What is the shelf life and information of other relevant storage conditions. The description of the environment should also include requirements for shock and vibration, including requirements from shipping, and production environmental conditions such as welding temperature and welding cycle duration. Manufacturers of magnetic connectors indicate that the area around the convergent continuous current guided by the magnetic connectors is the area where higher temperatures are generated.

  Fourth, mechanical performance requirements

  For magnetic connectors, what size and footprint are effective; what is the allowable dimensional tolerance; what is the insertion and withdrawal force of the terminal; and the durability of the magnetic connector (plug-in mating) How about the frequency)? These factors are all to be considered when choosing an electromagnetic connector. For example, for printed circuit boards, it is very important to determine the tolerance of the circuit board. It is the critical value of the card edge magnetic connector (card edge connection) , 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.

  5. Specifications Magnetic connector manufacturers can use about 25 testing institutions (specified specifications) as the source of all or part of their magnetic connector test specifications. Consideration must be given to the use of appropriate test specifications under specific application conditions, including internationally accepted conditions.
