RDH 100
For production environments: RDH 100 series RFID readers
Robust and can be installed in metallic environments
When automating production lines that require robustness and insensitivity to environmental influences, high-performance RFID systems are the preferred identification systems for continuously tracking individual production steps and ensuring quality requirements.
Space requirements are often very limited, especially in the production environment, in production cells and at assembly stations. Thanks to its design, the cylindrical RDH 142 high-frequency reader with a diameter of 30 mm can be mounted very easily and flexibly in metallic environments and delivers reliable identification results with a reading range of up to 60 mm.
The RFID reader is available in the RDH 142 version with IO-Link – for uncomplicated, fast use at the sensor level.
Highlights
With its compact, cylindrical design, the RDH 142 can be used in any situations that requires pinpoint detection in a confined space. With a reading range of up to 60 mm, the device offers enough scope for different application scenarios – even in metallic environments with harsh ambient conditions, for example in machining centers.
The RDH 142 reader is designed as an IO-Link version and thus for applications in factory automation and production control where a large number of sensors and actuators are installed in the system. The installation as well as the detection and transfer of data at production level must be quick and easy here. It should preferably be ideal for capturing small amounts of data, such as the 64-bit unique ID on the RFID tag that represents a container or workpiece. With the help of the supplied IO Device Description (IODD), any RFID reader can be integrated into the system control with little effort.
With its extended operating temperature range down to -32°C, the RDH 142 delivers the best value that allows applications to be implemented in deep-freeze areas. This primarily concerns applications in intralogistics.
Applications
Identification of components for quality monitoring in production
Requirement:
In the industrial production of technical components – for vehicles, for example – precise and accurate execution of the individual automated manufacturing processes is essential. Each sequential production phase must be monitored and the overall sequence of processing steps performed must be documented individually for each component in order to obtain quality data for the entire production process.
Solution:
The RDH 142 RFID reader offers the perfect solution for reliably identifying individual components or assemblies within the production process. On the other hand, quality data on individual processing steps can be stored directly on the component’s RFID transponder. For each subsequent processing step, the relevant information is first read out and further processing only takes place if the required quality information from the previous step is available. RFID thus controls production and provides continuous documentation of the component’s production quality itself.
Production control in production cells
Requirement:
Production cells are usually lacking in space. Identification systems must therefore be compact and offer good accessibility during installation. Individual production steps are initiated by identifying the RFID tag. A production process must be started with the correct parameters based on the individual tag detected.
Solution:
At M30 x 1.5 x 75 mm, the RDH 142 has very compact dimensions and can be installed very quickly thanks to its flexible mounting options. The implemented command sets also allow data to be written to the RFID tag, with full compatibility with high-frequency standards ISO 15693 and 14443A to provide a particularly wide choice of tags with different memory sizes. Additional information such as production parameters can be stored on the RFID tag.
Tool identification
Requirement:
Monitoring the presence of the right tools is particularly important in machining centers for metal components. This is true for pressing tools in sheet metal processing as much as for injection tools in plastics processing. The harsh environmental conditions require robust identification systems with high reliability.
Solution:
The compact high-frequency read head RDH 142 in a cylindrical housing can be easily installed in metallic environments and ensures the tool used can be queried at specific points. This ensures that the right tool is used and correctly positioned for each processing step. In addition, information about the tool’s operating time can be stored directly on the RFID tag attached to the tool so that maintenance cycles or tool replacements can be planned in advance.
