Application of Neodymium Magnets in the Communication Industry

Neodymium iron boron magnets are widely used in microwave communication technology, including radar technology, satellite communication, remote control, telemetry technology, electronic tracking, electronic countermeasure technology, etc. In addition, neodymium permanent magnets are also used in magnetron, klystron, cathode ray tube and circulator.

Neodymium iron boron magnets, mainly made of neodymium, iron and boron, are known for their high quality and competitive prices. They have high residual magnetism, coercive force and maximum excellent performance, and are widely used in energy products, such as motors, permanent magnet generators, electro-acoustic, hard disk drivers, magnetic separators, permanent magnet bearings, systems, switch technology, nuclear magnetic resonance analysis equipment, magnetic resonance imaging scanners, and relays.

Neodymium magnets are widely used in our daily lives. Below is a brief introduction to the common neodymium iron boron magnet detection applications in our daily lives. We hope you can gain inspiration from it and find the appropriate solution for your magnet application.

Ⅰ. Neodym magnets used in the communications industry

Dry spring sensors do not require an external power supply. In most cases, the load you need will be switched as soon as the reed switch is sucked in.

Normally, hanging up the phone is achieved through a mechanical hook switch. However, customized magnets or sensors can also be used to accomplish this task.

Signal communication applications:

1. Flip phone switch;

2. Telephone line switch;

3. Off-hook induction;

4. Interlocking;

5. Moving position induction;

6. Installation fault detection.

Ⅱ. How are neodym magnets used in telephones?

Normally, hanging up the phone is achieved through a mechanical hook switch. However, this can also be accomplished using a reed switch or sensor. The dry reed tube is directly mounted in the hand-held area (or receiver cover), and the magnet is mounted in the receiver. The reed switch and the magnet can be installed in many locations, depending on the specific requirements of the telephone.

In some cases, the magnet used in the hand-held microphone or hands-free microphone can provide enough magnetic field strength to suck in the reed switch when the receiver is lowered.

This method has greatly increased the demand for new phone models. The reasons are as follows:

1. The mechanical system is very fragile.

2. The mechanical pickup system may be damaged (especially in abused public phones).

3. The pickup system is susceptible to environmental interference.

4. The sealed reed tubes are not affected by any environmental factors.

Dry reed switches are not easily worn out. Because this application only switches low-level signals, the contacts can switch billions of times. This can greatly extend the life of the phone.
