Note: in metallic environment, both the reader and the tag may cause certain loss influence on the

recognition distance, so it is necessary to prevent the metal from directly surrounding the reader or adopt

anti-metal tag to increase the recognition distance.

3.1.4.2 Dynamic mode

During the operation under dynamic mode, the tag can dynamically pass through the

transmission window, and the movement speed of the tag relatively to the reader must meet the

following formula:

𝑉 ≤

2𝐸

V: relative movement speed of tag and reader head;

E: read eccentric distance of tag and reader head at application distance;

T: command execution period;

SG-HT-263 tag (surface length is 6 CM, and width is 3.3 CM) and SG-HR-15 tag are taken as

examples. When the application distance is 6 CM, the eccentric distance is 6 CM. When the

automatic tag memory read mode is adopted (16 bytes are read, and the command execution

period is 30ms), the applicable speed is as follows:

𝑉 ≤

2 ∗ 6𝑐𝑚

3 ∗ 30ms

= 1.34𝑚/𝑠

Note: in practical project application, if there is any metal around the tag and the reader head, the eccentric

distance will be reduced; the actually measured value should prevail in such case.

3.2 Reader and tag data

3.2.1 Read distance of the reader

The critical distance (Sg), the operation distance and the transmission window length

corresponding to different readers are as shown in the following table:
