RFID 125Khz EM ID Long Distance Card Reader Module TK4100 EM4100 Wg26
Rfid Reader Distance. Has the shortest read distance, about 10 centimeters between the reader and the tag. Tags that don’t have a power source.
RFID 125Khz EM ID Long Distance Card Reader Module TK4100 EM4100 Wg26
The more closely the rfid tag is ‘tuned’ to the reader frequency, the stronger is the signal. Web the working distance between a reader and a passive tag is greatest when they are in tune. Operates in a frequency range from 3 to 30 mhz. Has the shortest read distance, about 10 centimeters between the reader and the tag. The uhf rfid transceivers are designed to the global. Web low frequency rfid: This gives them a read distance from close contact to 25 meters. Generally speaking, rfid tag maximum read distances are as follows: Web 860 ~ 960 mhz. Web passive rfid tags:
Operates in a frequency range from 3 to 30 mhz. The hf rfid system tags, transceivers, and interfaces are designed to the iso 15693 open standard. Some tags are similar to labels that can be directly stuck on the windscreen of the cars. The more closely the rfid tag is ‘tuned’ to the reader frequency, the stronger is the signal. The read distance ranges from 10 centimeters to 1 meter. Has the shortest read distance, about 10 centimeters between the reader and the tag. These are the kinds of tags used in toll collection systems. You'll easily achieve to read passive tags from a distance of a few meters (up to 10m) by using any industrial uhf rfid reader ( impinj, thingmagic, stid,.). General equation to find distance to rfid tag is ploss = 20⋅log[(4 π ⋅ d)/λ] in case of uhf rfid, the equation to find the gap or distance to passive tag from the reader is pgap = 22.6(db)+ patt, where 22.6db is the power for near field(λ =c/f ≈ 35cm), where f is frequency operated, patt is the magnitude of power attenuator. Web what is the maximum read distance of rfid? Tags that don’t have a power source.
