Rockwell Automation’s Bulletin 45CRM Color Registration Mark Sensors offer high-speed response time and utilize three LED colors (red, green, and blue) to effectively differentiate between the color response of the mark and the background. These sensors are categorized as color sensors, as they detect RGB values by capturing ambient light using a photodiode. One notable feature of the 45CRM sensors is the incorporation of the embedded IO-Link communication protocol. This advanced feature helps minimize downtime and increase productivity. IO-Link enabled sensors offer a range of benefits, including Automatic Device Configuration, support for multiple profiles, trending capabilities, descriptive tags for easy identification, and device-specific parameters.
The sensors provide a fast response time of 40 μs, ensuring quick and precise detection of color registration marks. The setup of the 45CRM sensors can be done through dynamic teach, static teach, or IO-Link configurable methods, providing flexibility based on application requirements. Featuring an adjustable-position DC Micro (M12) quick disconnect (QD) cordset, these sensors offer convenience in installation and maintenance. The sensors are equipped with two complementary outputs (PNP/NPN push-pull), providing versatile connectivity options. In addition to their advanced functionality, the 45CRM sensors are compact in size, measuring 49 mm x 42 mm x 15 mm. This compact form factor allows for easy integration into various industrial settings.
It is worth noting that register sensors, such as the 45CRM Color Registration Mark Sensors, are designed to quickly and accurately detect control marks for register control applications. Alongside color registration mark sensors, Rockwell Automation also offers luminescence sensors, which are capable of detecting luminescent marks that are not visible to the human eye. When evaluating sensors, important static characteristics to consider include sensitivity, resolution, linearity, zero drift, full-scale drift, range, repeatability, and reproducibility. These characteristics define the sensor’s performance and reliability in capturing and interpreting measurements.
