More than HF: New Read/Write Devices Combine the Benefits of High-Frequency RFID with Unique Read Range Capabilities

Pepperl+Fuchs introduces a cutting-edge HF RFID read/write device series, marking a significant leap in identification technology. These devices seamlessly merge an exceptionally high read range with additional features, all encapsulated in a compact, optimized flat-pack design.

Built upon proven high-frequency RFID technology operating at 13.56 MHz, in line with ISO 15693 standards, these devices are tailored for guided industrial applications. They excel in scenarios where automatic identification of uniformly positioned and aligned objects or RFID tags is imperative.

The key focus of these HF RFID read/write devices is on flexibility, which is evident in their unique read range capabilities. With an adjustable detection range of up to 30 cm, users gain unparalleled adaptability, allowing these devices to be fine-tuned for specific applications. The revised flat-pack design ensures easy integration into diverse application environments.

A standout feature in this class of devices is their multitag detection capability. These HF RFID read/write devices can simultaneously identify up to 20 RFID tags in a single read operation, leading to swift throughput times and optimized processes.

Beyond flexibility and efficient detection performance, these devices prioritize process reliability. Complying with an IP67 degree of protection and designed for operation in temperatures ranging from -25 °C to +70 °C, they ensure robust performance even in challenging conditions. Additionally, the devices can autonomously test their resonance frequency, adapting to and mitigating interference from nearby metal objects.

The devices incorporate visible status LEDs for enhanced reliability, providing real-time information on their operational status. Faults and errors are promptly signalled through a red status LED or can be analyzed in detail using accessible software parameters. The devices also offer received signal strength indicator (RSSI) values, facilitating early detection of defective tags and preemptive exclusion from processes.

Integration of these HF RFID read/write devices into existing systems is seamless, with two versions catering to diverse user needs. The IQT3* devices, with an IO-Link interface, are suitable for Industry 4.0 applications, offering easy integration into architectures like PROFINET, EtherNet/IP, and EtherCAT. The IQH3* devices, on the other hand, are designed to interface with IDENTControl interfaces from Pepperl+Fuchs, catering to more complex applications and older Fieldbus protocols.

In conclusion, Pepperl+Fuchs’ HF RFID read/write devices present a breakthrough in identification technology, offering maximum application flexibility, reliable multitag capabilities, and autonomous adjustment to environmental interferences. With seamless integration options via IO-Link or IDENTControl, these devices provide a future-proof solution for diverse automation needs.
