RFID (Radio Frequency Identification)
Pepperl and Fuchs RFID (Radio Frequency ID Systems) can be used in many applications from EZ pass(monitoring who passes through a toll),some credit cards(when you wave your credit card over a device to pay), and also warehouse management applications to keep track of the quantity and location of products in your warehouse inventory. Where you used to need to scan bar codes in a direct light emitted path to identify a product like scanning at the Grocery store, now you can just use a powered (active) or (non-powered) passive RFID Device to track the location of and identify your product. These products use different frequencies like a radio signal from a radio antenna, when you are within this emitted area you can listen to that radio station, so when you are within the emitted field from an RFID Signal you can track your product. You should select your system by the distance the product is from the signal. Some of the frequencies are UHF at 868 MHz (like good old Fox 29 and Philly 57 TV stations which is now used for other purposes), Microwave at 2.45 GHz (very close to your home wireless router frequency at 2.47GHz),low-frequency at 125 or 250 kHz, High-frequency at 13.56 MHz. Here are the Pepperl and Fuchs RFID devices that you can purchase from Airline Hydraulics.

|
| UHF far field RFID, signal transmission at UHF at 868 MHz |
- Read/write distances measure several meters. The carrier frequency, and sending and receiving on various channels yield high transfer rates.
- UHF transponders can be active and passive. Passive transponders are very cost-efficient to manufacture, and can be easily attached to objects.
|
| Far field RFID, signal transmission with microwaves at 2.45 GHz |
- Benefits include long read distances of up to 4 meters, high transfer rates and pass-by speeds.
- Spatially extended and fast-moving objects are captured, making it ideal for barrier control applications.
|
Transponders and read/write heads |
- Transponders accompany goods and persons along the value chain. They carry information for reliable object recognition. Writable transponders can also register process data.
- RFID heads read or write to the transponders and communicate with the control unit.
|
| Low-frequency near field RFID, inductive signal transmission at 125 or 250 kHz |
- Read/write distances range from several centimeters to decimeters. Transfer rates and pass-by speeds are slightly lower than higher frequency RFID technologies.
- A variety of transponders are available. Transponders are insensitive to mechanical, thermal, chemical or electromagnetic influences.
- Identify work piece carriers by installing a transponder with a ferrite core into metal.
|
| High-frequency near field RFID, inductive signal transmission at 13.56 MHz |
- Works three to four times faster than low-frequency technology.
- Transponders are small and in the form of adhesive labels.
- Transponders cannot be installed into metal, however special transponders can be fitted onto metal.

RFID control units
Pepperl+Fuchs control units provide you with solutions for mechanically, thermally, chemically and electromagnetically demanding environments. Our RFID control units:
|
- Act as the gateway to the control, communication, and power supply of the read/write heads.
- Connect the read/write heads with the higher-level automation system, filter read-in data and control write/read processes.
