The new RFID readers for flexible use in production and logistics score points with their compact design, reading ranges of up to 100 mm, 

flexible mounting options and IO-Link.

Owen, 5 May 2025 – If you want to reliably track every step in automated production lines and logistics, you need powerful, robust sensor 

technology that is as compact as possible. Leuze presents its new RFID readers that optimally fulfill these requirements: The devices in the 

RDH 100 and RDH 200 series operate in the high-frequency range. They stand out for their reading ranges of up to 100 mm, compact design 

and flexible mounting options. The devices have an IO-Link interface for uncomplicated, fast use at sensor level. Plus the RFID readers are 

temperature-resistant down to -32°C during operation, making deep-freeze warehouse applications easily possible.

RDH 100: Compact und robust
Where space is tight in production environments, production cells or assembly workstations, an RFID reader from the RDH 100 series is the 

ideal solution. The cylindrical RDH 100 reader has a diameter of just 30 millimeters, allowing it to fit into the smallest of gaps. The RFID 

reader detects transponders with pinpoint accuracy and a reading range of 60 millimeters. It has a very robust design: The metal round 

sleeve version (with M30 x 1.5 thread) offers optimum mechanical protection against external influences and a high level of ingress 

protection (IP 67). This allows the reader to be used flexibly in different areas – even in machining centers for metallic components where 

harsh environmental conditions prevail.

RDH 200: NFC functionality included
The RDH 200 series is suitable for NFC applications too: The readers can also be used for authentication on machines via NFC tags, for 

example. The RDH 200 series offers a large reading range of up to 100 millimeters – yet the devices are also extremely compact 

(68 x 68 x 42 millimeters). This allows them to be used flexibly in production control and assembly. Practical installation: The back of the 

device is designed as a mounting plate. This enables flexible, quick fastening with screws and provides particularly good accessibility. 

The plate also allows it to be mounted directly on metallic surfaces.
