The new IO-Link compatible sensor range from Omron currently incorporates through-beam, retro-reflective and diffuse reflective photosensors, colour mark sensors, standard proximity sensors and spatter-resistant proximity sensors. All types are available with pre-wired connections, with standard M8 connectors or with M12 Smartclick connectors that offer faster and more convenient installation. The many innovative features offered by the new sensors include the ability to continuously monitor and report their own performance and support on-the-fly reconfiguration using data transferred by the automation system.
The sensors are complemented by two IO-Link master modules, one with screwless clamp terminals for use with pre-wired sensors, the other with Smartclick connectors. Both master modules allow the connection of standard sensors, as well as the new IO-Link types, making it easy to upgrade existing machines and systems. IO-Link is an open international standard supported by more than 100 companies, including major sensor manufacturers. It provides bidirectional communication and, as well as supporting typical sensor and actuator signals, it also allows the sensors and actuators to exchange status information and operating parameters with the automation system.
This means, for example, that a sensor can generate an alert when its performance starts to fall off because of the build up of soiling, allowing this to be corrected before it results in a machine stoppage. The ability to send new parameters to the sensors is particularly useful in machines that handle more than one type of products as, in many applications, it eliminates the need for manual intervention in changeovers.
