Swiss Sensor and RFID Innovators

Founded in 1972, the Swiss manufacturer Contrinex is a technology leader in sensor communication and devices for demanding operating conditions. The product range includes sensors of all kinds, from conventional standard sensors to high-performance devices that push the detection properties of sensors to their physical limits and give this sensor manufacturer its essential difference.

As an innovator of high-tech sensing equipment, our business is to provide customers with significant technical advantages that will support their success. Contrinex’s market-leading products are manufactured to the highest Swiss standards, ensuring excellent quality and reliability.

Our customers also benefit from a worldwide network of subsidiaries and qualified sales representatives in over 60 countries. At our headquarters, experienced application and development engineers can also help you find optimum solutions for all sensing problems.

HF/LF RFID tags and read-write modules

Contrinex high frequency RFID technology (13.56 MHz) is ISO/ IEC 15693 compliant and particularly user-friendly. Up to 254 R/W modules (RWMs) can be connected directly to an RS485 network. Fieldbus interfaces are available for connecting up to 31 RWMs. A Contrinex USB adaptor can connect a network of up to 10 RWMs for direct control by a PC. IO-Link RWMs are also available. Software is easy to develop and maintain, thanks to a library of PLC function blocks.

Contrinex low frequency RFID technology (125 kHz, operating frequency: 31.25 kHz) features not only conventional metal/PBTP components, but also a range of all-metal read/write modules and transponders in stainless steel. These devices have high resistance to mechanical shocks and are particularly well suited to the harshest operating environments. If the ContriNET protocol is used, LF RWMs have the same networking advantages as HF RWMs.

Success Story: HF RFID Read/Write Heads With IO-Link

Interview with Norbert Matthes More and more RFID customers are choosing Contrinex’s HF RWMs with IO-Link. This comes as no surprise at all to Norbert Matthes, Technical Sales Manager with Contrinex Sensor GmbH in Germany and RFID workshop specialist. Who better then to answer our questions and explain the special appeal of the IO-Link RWMs?

HF RFID – FB library for extremely easy IO-Link integration with S7-PLC

The new function block library from Contrinex simplifies the integration of IO-Link read/write modules in RFID projects and thus reduces engineering time and costs. This library covers all the necessary functions for communication with a Simatic S7-1200/S7-1500 or equivalent PLC. The user can drag and drop the required IO-Link function block into the corresponding network and store it there. It’s that fast and easy.

Long-range Photoelectric Sensor Counts Shrink-wrapped Carton Packs

During high-volume confectionery packaging operations, conveyors deliver stacked cartons to shrink-wrapping stations. At each station, a wrapping machine encloses a stack in heat-shrink film and an infrared oven shrinks the film to form a sealed pack of cartons. A long-distance through-beam photoelectric sensor, mounted beside the conveyor, senses the presence of each pack as it leaves the oven and signals a plant-wide control system to increment the production throughput totals.
