Metal detectors are essential tools in the MRO and automation industries, designed to identify and locate metallic objects within various materials or environments. They are widely used in quality control, security, and industrial maintenance. Common types include handheld detectors for portable use, walk-through gates for security screening, and inline systems for automated production lines. Key features often include adjustable sensitivity, discrimination capabilities to filter out unwanted metals, and rugged designs for harsh environments. Products in this category may range from basic models for general-purpose detection to advanced systems with data logging and integration capabilities for industrial automation.
