The Allen Bradley 42CM-D8MNA-D4 is a cylindrical metal sensor designed for reliable detection in industrial settings. Featuring an 18 mm mounting diameter, this sensor operates with a laser-based, standard diffuse sensing method, making it effective at identifying metal objects within its range. It includes a handy teach button for easy setup and adjustment. The device uses an NPN output with a complementary DC load, connected via a 4-pin micro quick-disconnect interface. With a fast response time of 0.7 milliseconds, it can sense metal targets as close as 3 mm and as far as 300 to 400 mm, depending on the specific conditions. This sensor is available through BSP Automation, offering solid performance for automation applications where precise metal detection is required.
