Our line of walk-through metal detectors ensures quick and non-intrusive screening, enhancing the overall safety of airports, event venues, and other public spaces. These detectors feature adjustable sensitivity settings, allowing you to identify potentially hazardous metallic items, regardless of their size.
Walkthrough metal detectors are security screening portals that use electromagnetic field technology to detect metallic threats on persons passing through. Standard equipment at courthouses, schools, stadiums, government buildings, and high-security facilities. Available in 18–90 zone configurations for indoor and outdoor deployments.

A walkthrough metal detector is a security screening portal that uses electromagnetic field technology to detect metallic objects on a person passing through it. It is the standard security screening tool at airports, courthouses, schools, stadiums, government buildings, and high-security facilities worldwide.
Walkthrough metal detectors generate a continuous low-frequency electromagnetic field between transmitter and receiver panels. When a metallic object passes through the field, it creates a distortion that triggers an alert. Multi-zone models pinpoint the location of the detected object on the body, helping security officers respond faster and more accurately.
Walkthrough metal detectors detect ferrous metals (iron, steel), non-ferrous metals (aluminum, copper, brass), and alloys. Modern multi-zone detectors can detect handguns, knives, metallic contraband, and large metallic objects while filtering out common items like belt buckles and small jewelry through adjustable sensitivity settings.
The number of zones refers to how many distinct detection areas the portal has from head to toe. An 18-zone detector divides the body into 18 detection segments for approximate threat location. A 90-zone detector provides much more precise location data, reducing false alarms and helping officers identify exactly where a threat is located, which is critical for high-throughput screening environments.
Yes. 2M Technology offers outdoor-rated walkthrough metal detector models (IP65 or higher) designed for outdoor checkpoints, stadium entrances, event perimeters, and construction sites. Outdoor models are weatherproofed against rain, humidity, and temperature extremes.
Under standard operating conditions, walkthrough metal detectors process 300-600 persons per hour per lane depending on the model, sensitivity settings, and whether bags are screened separately. High-sensitivity multi-zone models may require secondary screening for alerts, reducing effective throughput to 200-400 persons per hour in practice.
Walkthrough metal detectors are used in courthouses, schools and universities, hospitals, correctional facilities, stadiums and event venues, airports, government buildings, houses of worship, corporate campuses, warehouses, manufacturing facilities, and any location requiring person screening for metallic threats or contraband.
Yes. A complete primary screening lane pairs a walkthrough metal detector with an X-ray baggage scanner — persons walk through the metal detector while their bags pass through the X-ray conveyor simultaneously. 2M Technology designs and installs complete screening lane configurations including both components.
