Product Description
The Allen-Bradley 42CRC-4000 Photoswitch color registration controller detects pre-printed registration marks on contrasting backgrounds using Automatic Gain Control (AGC) technology to sense grayscale differences. It features red and green LEDs for color registration, operates in latch or non-latch modes, and supports light/dark mark sensing, automatic/manual operation. Requiring 10-30V DC at 70mA, this controller has an NPN open collector output and a minimum web velocity of 2 inches per second. It measures 97x75x22mm, weighs 350g, and must be mounted over an opaque plate to avoid false readings. A Photoswitch cable assembly (available separately) is needed for connection.
Is Your Device Showing These Signs?
The Allen Bradley 42CRC-4000 light curtain commonly experiences issues such as sensor contamination leading to beam blockage and false trips. Resolving this involves cleaning the optical surfaces and verifying proper alignment. Cable damage, particularly to the M12 connectors, causes communication failures, necessitating cable replacement or connector repair. Power supply fluctuations result in erratic behavior; confirm the power supply meets the specified voltage and current requirements. Internal component failures within the controller demand repair or replacement of the safety light curtain system. Configuration errors in the safety controller parameters also trigger faults, requiring a review and correction of the safety logic.
