The magnetic connector, primarily composed of a pogo pin and a magnet, is widely used in electronic equipment and is designed by the structure of a magnet and magnet contacting and attracting.

The main performance of the magnetic connectors

Anti-fall: the interface is easy to remove, and it is not easy to drive the machine;

Long life: up to 100,000-200,000 times of functional connection and charging;

Waterproof design: The female end of the host can be completely dustproof and waterproof (IPX8);

Fast charging time: accept large power transmission 5A-10A design;

Save space: the female end connector and the PCB transfer can complete the POGO type and SMTDIP jumper connection;

Customization: Diversified shapes and styles to match the shape of the host product and to enhance the product level selling point;

Magnet positioning: application of double junction of magnet and mechanism to maintain the whole circuit to prevent fools;

Environmental protection requirements: excellent corrosion resistance level to meet harsh environments.

Application characteristics of magnetic connectors

1. Characteristic impedance

The characteristic impedance of BNC RF connectors is 50Ω and 75Ω. Many series of connectors are available in both 50Ω and 75Ω sizes. Generally speaking, 50Ω connectors are mostly used in high-frequency, high-performance products; 75Ω connectors are mostly used in products with lower frequencies, and the frequency is below 4GHZ, especially in consumer electronic video. Users must choose a connector that matches their impedance according to their products; for example, if the user uses a 75Ω RG 59 CABLE, he should choose a 75Ω connector.

2. Frequency

Each RF connector has a frequency range, and users need to understand the operating frequency of their products to select connectors. For example, choosing a connector with a lower frequency than the required operating frequency will affect the electrical performance of the whole machine, or choosing an expensive high-precision high-frequency connector will cause waste. It should be noted that the use frequency of connectors designed by different companies is quite different, and the use frequency of inferior products needs to meet the industry requirements. Therefore, when choosing a connector, the user should confirm the electrical performance description of the product.
