Allen Bradley 45CRM colour registration mark sensors have a high-speed response time and emit three LED colours (red, green and blue) to discern the difference in colour response between the mark and background. IO-Link enabled sensors offer advanced features and diagnostics including Automatic Device Configuration, multiple profiles, trending, descriptive tags, and device-specific parameters

This colour sensor from Rockwell Automation's Allen Bradley range scans the surfaces of objects to ensure they match a pre-set colour. It projects red, green and blue LED lights and measures the differences in their reflections to determine the object's colour. A fast response time of 40μs (microseconds) ensures quick colour detection to reduce downtime and improve efficiency. Thanks to its broad operating temperature range of -20°C to +60°C, this device is suitable for use in demanding industrial environments.

• Die-cast zinc housing material is corrosion-resistant for long-lasting performance
• IP67 (ingress protection) rating for protection against dust and submersion in 1m of water for up to 30 minutes
• Rotary switch to easily adjust sensitivity rate

• CE (Conformitè Europëenne)
• cULus (Underwriters' Laboratories in Canada and the US)

A colour sensor like this unit is specifically designed to read the colour of an object, while a contrast sensor measures the differences in the shades of a colour compared to a pre-set value.
