Our Bulletin 45MLA Measuring Light Array Photoelectric Sensors detect or measure targets in a two dimensional area—even if the parts are irregularly shaped, sized, or positioned. These sensors can detect and communicate individual beam status to measure and determine the position of objects. The emitter and receiver arrays are connected to a separate controller. All I/O, communications, and power connections are wired to an external controller. We offer controllers with various functions and/or communication interfaces: I/O, CAN, RS485, Binary, and Analog.
