RDH 142 – Compact HF RFID Reader for Industrial Applications
Robust, compact, and ideal for metallic environments: The RDH 142 from Leuze is a powerful high-frequency RFID reader in a cylindrical M30 housing. It is specifically designed for industrial manufacturing, assembly, and logistics applications. Thanks to its rugged design, the device can be mounted directly in metallic environments—without any performance loss.
Reliable identification even in harsh conditions: With a reading range of up to 60 mm (depending on the RFID transponder), the RDH 142 enables accurate object detection, even in tight spaces and demanding environments. Its extended temperature range down to -32 °C makes it suitable for cold storage and deep-freeze logistics.
Easy integration via IO-Link: The RDH 142 is fully IO-Link capable (Version 1.1.3) and can be quickly integrated into existing control systems using the appropriate IODD. This simplifies commissioning and reduces installation time.
Key Benefits at a Glance
High reading range in a compact form factor: Up to 60 mm reading distance for flexible use in manufacturing and assembly.
Full IO-Link compatibility: Seamless and standardized integration into industrial control systems.
Cold-resistant design: Operates in environments as low as -32 °C – ideal for frozen and chilled logistics.

RDH 200 Series
RDH 202/242 – Compact RFID Readers with NFC Support
The RDH 202 and RDH 242 RFID readers from Leuze are designed for industrial environments where space is limited, such as assembly lines and conveyor systems. With a compact form factor and a reading range of up to 100 mm (depending on the transponder), these high-frequency (HF) readers offer reliable identification in challenging conditions.
In addition to supporting the industry-standard ISO 15693, the devices also read and write tags based on ISO 14443A. This makes them suitable for NFC applications, including machine access control using NFC Forum Type 2 and Type 5 tags.
The RDH 242 is available with IO-Link (v1.1.3) for fast integration into automation systems, while the RDH 202 offers an RS-232 interface for direct serial communication.
