Rfid Tag Frequency Range

Each frequency has its unique benefits that provide customers a way to track assets in even the.

Rfid tag frequency range.

Typical hf rfid applications include tracking library books patient flow tracking and transit tickets. Ultra high freqency uhf rfid 433 mhz 900 915 mhz. However the range of the low frequency range is limited to a few centimeters. High frequency tags work fairly well on objects made of metal and can work around goods with medium to high water content.

Frequency specific details 125 khz. Low frequency lf passive rfid tags. Passive rfid tags have a more limited read range up to around 20m. Typically hf rfid systems work in ranges of inches but they can have a maximum read range of about three feet 1 meter.

If you re planning to use rfid you need to know what distance it will work over. Typical rfid applications using low frequency include access control and tagging of animals. 125 134 khz low frequency lf an extremely long wavelength with usually a short read range of about 1 10 centimeters. There are three main frequencies within which passive rfid tags operate.

Rfid radio frequency identification is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object animal or person. Radio frequency identification rfid uses electromagnetic fields to automatically identify and track tags attached to objects. Gao offers a large selection of rfid tags or transponders using different radio frequencies including active 2 45 ghz active 433 mhz ultra high frequency uhf 865 868 or 902 928 high frequency 13 56 mhz and low frequencies 125 khz and 134 khz that can be read by compatible rfid readers. Rfid range is fundamental.

High frequency rfid or hf systems. Read distance of 30 cm 1 foot or less usually 10 cm 4 inches unless you are using a very large tag which can have a read distance of up to 2 meters when attached to metal. Passive uhf tags in the frequency band 856 960 mhz are commonly used for asset tracking and inventory management. Ultra high frequency uhf much of the crossover or comparison between rfid and nfc concerns uhf rather than lf rfid tags.

Memory on rfid tags is very limited due to the low data transmission rate and high production cost. A radio receiver and transmitter. An rfid tag consists of a tiny radio transponder. When triggered by an electromagnetic interrogation pulse from a nearby rfid reader device the tag transmits digital data usually an identifying inventory number back to the reader.

Low frequency lf rfid 125 khz 134 khz. This depends on rf transmit power the receive sensitivity the surroundings how much water is present the orientation of the tag frequency of operation and the care that s gone into designing the products planning and installing the system.
