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

The factors that need to consider

Magnetic connector type

Use must be considered first, determining the type of industrial magnetic connector selected. Magnetic connectors will be affected by indoor and outdoor locations and corrosive environments. The type of magnetic connector determines which terminals are used and the number of conductive terminals arranged.

Electrical requirements

When selecting, consider the electrical requirements of the product. The voltage and current requirements of the product and whether the magnetic connector can be well used in electrical properties all need to be considered. In addition, other electrical conditions also 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), interpolation pull-out loss and EMI shielding efficiency.

Environmental requirements

Temperature, humidity, and other environmental conditions depend on the location of the magnetic pickup connector, so take that location and expected environment into consideration. As for other relevant storage conditions, the applicable period and information, etc., 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. In addition, the area where the magnetic connector directs the combined continuous current is where the highest temperature occurs.

Mechanical performance requirements

What volume and coverage area are effective, what is the allowable dimensional tolerance, what is the terminal’s insertion and extraction force, the magnetic connector’s durability (frequency of plugging and unplugging), etc., should be considered when choosing a magnetic connector. For example, when using a printed circuit board, it is very important to confirm its circuit board tolerance, which is the critical value of the card edge magnetic connector, and the feasibility of reaching the critical value. For low-power circuits, the coating and underlying materials must be specified to be consistent with signal standards and environmental levels.


Be sure to consider the selection of the appropriate test specification for a specific application, including those used internationally. Pomagtor magnetic connector can pass all of the magnetic connector test specifications. Contact us if you need magnetic connector.
