Does working in RF hurt?

There is harm, there is radiation.

Indicates the electromagnetic frequency that can be radiated into space, the frequency range from 300kHz to 300GHz. Radiofrequency is radio frequency current, a high-frequency alternating current changes in electromagnetic waves, less than 1,000 times per second change in alternating current is called low-frequency current.

More than 10,000 times called high-frequency current, and radio frequency is such a high-frequency current. Radio frequency (300K-300G) is a high frequency (greater than 10K) of the higher frequency band, microwave band (300M-300G) and is the higher frequency band of radio frequency.

RF characteristics:

Working in the low-frequency inductor's general operating frequency from 120kHz to 134kHz, TI's operating frequency of 134.2kHz. the wavelength of the band is about 2500m;

1, in addition to the influence of metal materials, the general low-frequency can be passed through the items of any material without reducing the distance of its reading.

2.

2, work in the low-frequency reader in the world without any special license restrictions.

3, low-frequency products have different forms of packaging. A good package form is too expensive, but has a service life of more than 10 years.

4, although the frequency of the magnetic field area drops quickly, but can produce relatively uniform read and write area.

5, compared with other frequency bands of RFID products, the frequency band data transfer rate is relatively slow.

6, the price of the sensor is more expensive than other frequency bands.
