Its characteristics are as follows:

1. The relay has a large capacity, low air consumption, good stability, and high sensitivity;

2. High precision of electromagnetic components;

3. Adjustment and maintenance can be carried out directly in working condition;

4. The magnet is made of high energy storage rare earth materials, and the current is input through elastic elements without the need for leads.
