Contrinex UK introduces new radio sensing system

The use of battery-free transponders is a major advantage in that it avoids the limitation of operating temperature range and operational life experienced with battery powered tags. In addition, with this new Contrinex system the tags can be fully embedded so reducing the chance of collision damage that is common with surface mounted tag arrangements.

RFID technology has a fundamental advantage over the application of conventional laser marking and bar code systems in that transponder information can be up-dated and carried with the product that is in process without reference to any main control system. Stored data can include production details as well as test data. This information can be used to make local decisions on different product options such as which processes are required on flexible manufacturing machinery or whether to complete an assembly if any test criteria have not been met. The information can also be used for storing records for future production QA traceability.

The Contrinex system comprises a range of steel or plastic transponders containing an integrated circuit connected to an antenna and read/write modules linked to an interface module that can accommodate up to four read/write modules. All three interface device formats are available in versions for connection to Profibus, DeviceNet and RS485 and are supplied with free application software. The provision of a four-way interface module reduces the component count and costs.

Contrinex supplies smooth, all-metal transponders in diameters 10, 16 and 26mm and threaded metal transponders in sizes M16 and M30. Synthetic transponders, made from tough, nylon PA6, are available in diameters of 20, 30 and 50mm. All sizes are available in embeddable format.

The all-metal transponders and read/write modules are made from stainless steel, including the sensing face of the transponder and can withstand extreme impact, high shock levels and are highly resistant to chemical stress. All transponders have read and write capability, have a memory of 2 kbits and word or memory zones that can be read and/or write protected. The Contrinex RFID range also includes a portable read/write device for commissioning and trouble shooting on the shop floor.

The Contrinex RFID system will find use in numerous industrial identification applications including: high temperature autoclave processes, tracking in aggressive conditions, pallet assembly machinery, automotive sub-assembly production, car engine build and similar manufacturing processes. In engine build applications the tag data includes storage of the engine’s specification, identity numbers, all set-up and test details and these remain with the engine for life.

Within just a few weeks of Contrinex launching the RFID range, a global pharmaceutical company ordered a major system for in-process tracking on one of the critical processes here in the UK.
