Identification Systems - Introduction Inductive identification systems

The simple fixed code systems are often used instead of barcode systems. They have the advantage of offering a 100% read guarantee, not requiring a direct visual contact to the code carrier, operating reliably and durably, even under harsh environmental conditions.If the read distances do not have to exceed 15cm, an inductive system should be preferred over the microwave identification system for cost rea-sons.If a lot of code or data carriers are required in the system, the IDENT Con-trol with IP heads should be selected. If there are particularly strong outside influences due to electromagnetic interference, the systemIV is the most suitable choice due to the frequency modulation method.

Microwave identification systems

If very high passing speeds or ranges of up to 4 meters are required, the microwave identification system is the suitable solution. If the system is to be operated via an application-specific software in the device itself without a Fieldbus connection, the systemMT is the right choice.If the system is to be connected to a Fieldbus and ranges of more than 0.5m for writing the data are required, the IDENT Control with the MV an-tenna should be selected.

Optical barcode systems

If the code carriers remain at the product and only a fixed code system is required, using a system that works optically with barcode is the most cost-effective solution. During usage, the code carriers must neither become dirty nor scratched. A data volume of up to 128 bits can be stored using the barcode.

Optical Data Matrix systems

If there is less space required and the memory requirement is greater, the Data Matrix Code offers a higher storage density. The Data Matrix Code ECC200 is a frequently used standard, which only needs a surface of some square millimetres. Memory contents of up to 8Kbits are possible. Other advantages include standardised codes and the possibility of an automatic error correction.Both optical code types can be easily generated using standard industrial printers and are thus unbeatably cost-effective.
