Key Features
Read/Write Capability: Can both read data from and write data to compatible ISO 15693 RFID tags. This allows for updating information (e.g., process steps, quality data) directly on the item being tracked.

High Frequency (HF) Operation: Operates at 13.56 MHz, providing short-range, stable, and fast data exchange with high immunity to environmental interference like metal or moisture.

Long Read Range: Offers an extended detection range of up to 70 mm, which is significant for HF technology, providing more flexibility in installation.

IO-Link Interface: Equipped with IO-Link V1.1, a standardized IO technology (IEC 61131-9). This enables:

Simple Parameterization: Easy setup and cloning of sensors via the controller.

Advanced Diagnostics: Continuous monitoring of system status and signal quality.

Process Data Integration: Seamless integration into higher-level control systems.

Metal Mounting Capability: The design allows for flush mounting in metal without loss of performance, which is a critical advantage in industrial machinery.

LED Status Indication: Integrated LEDs provide clear visual feedback on operating status (power, communication, error).

Rugged Industrial Design: Features a metal housing with a PPS (Polyphenylene sulfide) plastic sensing face, providing high resistance to chemicals, oils, and mechanical impact.
