COLOUR SENSOR OPENS NEW OPPORTUNITIES IN INDUSTRIAL MONITORING
With a wide range of safety technology, Automation24 has already adjusted its offerings to meet the needs of its customers in the first half of the year. Now, Datalogic’s safety light curtains are available for almost all common manual workstations and test benches.
position detection. Unlike conventional light barriers, the transmitter of a safety light curtain transmits a multitude of light beams at defined distances to the receiver module, and thus forms a close-mesh barrier between the hazard area and the user. As soon as the light pulses are interrupted, for example because a finger, hand, or other limb has crossed their path, machines can be automatically stopped, and injuries avoided. The devices from the Datalogic SG4 Base range also have adjustment options that enable the prevention of unexpected downtime. This includes, for example, OSSD outputs, which emit periodic test pulses in order to detect potential short circuits.

AUTOMATION24.CO.UK
In order to find the right safety light curtain for the respective device or machine, Automation24 offers support on its website, in the form of a table with selection criteria. As further assistance during installation, users will find a calculation formula to determine the correct minimum distances between the light curtain and the hazardous area. Tips for installation and ensuring the flawless function of the devices round off the guidelines. “We also offer an instant availability display via the webshop. With Datalogic, we can rely on a long-term partner with whom we have had positive experiences and can thus offer our customers good value for money,” says Schulze.

mron Electronic Components Europe has introduced its B5WC Colour Sensor, which enables monitoring of
equipment, plant, and industrial processes through detection of small colour changes. Specific applications are being developed through co-creation with industry partners. The colour sensor uses a white LED to emit light and receive reflected light according to the colour of detected objects. The colour sensor separates received reflected light into red, green, and blue, then outputs RGB data as voltage values using the I2C interface.
Applications range from monitoring of lubricant deterioration in robot arms and elevators, through drinks dispensers, to object detection on production lines. Omron’s new B5WC promises an innovative solution to these issues. For example, the colour sensor monitors oil deterioration in hydraulic equipment used in industrial machinery - in real time using colours to monitor the condition of the oil. Providing maintenance at optimal timing is vital for manufacturing plants. Minimal production losses within manufacturing sites contribute to carbon neutrality. Development of sensing technology and optical design technology enables simpler integration into the equipment thanks to compact size. Plus, integrating I2C communications into the sensor streamlines embedding in the equipment. The new sensor helps customers to remotely monitor equipment deterioration in real-time, leading to the visualisation of the equipment and the reduction of person- hours required for inspection and maintenance. It offers solutions to the problems faced by the industrial machinery and hydraulic equipment industries through highly efficient and systematic maintenance.
At manufacturing sites, oil
contamination is frequently a cause of failure of industrial machinery and hydraulic equipment. Maintenance personnel are relied upon to conduct a visual check for such contamination, often by performing periodic inspection and part replacement based on their intuition, tricks, and experience. Often production stoppage losses due to sudden equipment breakdown are incurred by inconsistent judgment from each person in charge. In addition, delays in inspection timing have been a longstanding issue. There is also the increasing need for higher efficiency in maintenance and remote monitoring due to a severe shortage of labour and limited accessibility due to the COVID pandemic. Until recently, size and cost of additional components have stood in the way of solving the problem. To resolve these issues, the new B5WC sensor can be embedded in the equipment that quantitatively monitors oil deterioration based on colour changes. Based on OMRON’s innovative sensing technology and optical design, the new product is readily integrated into the equipment thanks to compact size (W:40mm x D:8.4mm x H:15.9mm) and communication method (I2C), which are suitable for embedding in the equipment. Prior to commercial introduction, the B5WC successfully completed four years of field tests on the “Eco-Rich R” hybrid hydraulic system provided by the Oil Hydraulics Division of Daikin Industries. Future applications are planned for manufacturers of drinks dispensers and object detection, with development on a co-creation basis.
