\nA Door Frame Metal Detector (DFMD) works on the principle of electromagnetic induction. It detects changes in a magnetic field caused by the presence of metallic objects as a person passes through the frame. A Multi-Zone DFMD provides better spatial resolution, indicating the approximate height location of the detected metallic item. Regardless of sophistication or the number of zones, the core function of a DFMD is limited to detecting metallic items.
\n<\/section>\n
\nDFMDs are designed specifically for the detection of metals.
\n<\/section>\n
\nDetection of non-metallic items or explosives requires different technologies such as X-ray scanners (for density and shape), trace detectors (for chemical residues), or advanced imaging systems. While some modern screening systems might integrate multiple technologies, a device solely described as a Multi-Zone DFMD primarily performs metallic item detection.
