Short-range RFID for harsh environments
Especially high-performing and flexible are the BIS C low-frequency RFID systems with the reliable tool identification in coolant- and lubricant-enriched machining centers. An exact positioning is not always necessary. Many data carriers can also be dynamically read and described "in passing".
LF (70/455 kHz) is the first choice for the tool identification over short ranges. Other areas of use are tool transport with conveyor systems, FTS and pallet transport systems and the assembly technology and organization of supplies.
LF data carriers accompany the workpieces through the entire production process. In this context, they are exposed to extreme conditions such as high temperatures, metal enclosure or environmental influences.
Data carriers from Balluff withstand the high requirements: They are insensitive to interference in metal enclosures, high-performing in refrigerant and lubricant-rich environments and suitable for use in deionized water in an autoclave or in a vacuum.
Our application-specific LF read/write heads and antennas in industrial-grade design are easy to integrate into your system. Their robust housings in protection type IP67 ensure a reliable use even in harsh industrial environments.
Depending on the need, various versions with cable or plug connections are available. Up to four read/write heads can be connected to BIS V processor units. The read/write range depends on the combination of read/write head and data carrier, which is also affected by operating mode (static vs. dynamic), the mounting material and the clear zone from metal.
Our LF read/write heads with integrated processor unit combine everything in one housing: Antenna, electronics and interface. For quick and easy data carrier programming, you can use the free PC software BIS Cockpit. Alternately, it is also possible to program the data carrier using a processor unit with a serial connection and Balluff 007 protocol.
Our LF read/write units are perfect for portable reading and writing of BIS C data carriers. They are used with manual quality control or in the documentation of maintenance procedures.
The data is transmitted via WLAN, Bluetooth or cable-connected USB port. The handheld devices are expandable with 1D or 2D barcode readers. They deliver reliable results even with poor lighting and under harsh conditions.
With our BIS V processor unit, you can simultaneously use up to four read/write heads per processor. The BIS V allows mixed operation of all frequencies (BIS M, BIS L, BIS C, BIS U). Thus only one type of processor unit needs to be stocked, which greatly simplifies inventory management. For use in any industrial sector, the processor unit is available with all globally standard bus systems.
LF data couplers from Balluff ensure the greatest possible flexibility. They securely transmit the data via two air interfaces. In doing so, they handle the contactless bridging of the two transitions instead of a fixed data transmission.
The data couplers are generally used where a double mechanical interface is indispensable, for example, with rotary tables, replaceable workpiece holder or gripper arms. This way, you are able to simplify your system design and increase system availability because of fast contacts, like in tool changing.
