SMD601® Plus Walk-Through Metal Detector
The SMD601 Plus is a highest-sensitivity multi-zone metal detector designed for advanced security and high-risk screening environments where precise detection of even the smallest metallic threats is critical. It provides fast and accurate analysis of all areas of the body, from shoe level to the crossbar, with precise pinpointing of individual and multiple metal targets. Built for reliable operation in demanding environments, the system offers strong resistance to external interference along with a durable, high-protection mechanical structure. The SMD601 Plus also features highly visible control and zone indicators that remain easy to monitor regardless of operator position or installation environment, supporting efficient and consistent screening operations in critical infrastructures and loss prevention applications
Ultra-High Sensitivity for Correctional Environments
The SMD601 Plus is the most sensitive walk-through metal detector, fully compliant with both NIJ-0601.02 and NIJ-0601.03 standards, and designed specifically for law enforcement and correctional facilities that require detection of even the smallest metallic threats. This system extends detection sensitivity beyond the previous SMD601 to detect metal threats previously considered undetectable due to their minimal dimensions, including disposable razor blades, special metal items (AISI 300 series stainless steel), and bullets as specified in the new NIJ-0601.03 Standard. Quick, accurate analysis covers all parts of the body from the shoe level to the crossbar, with 20 vertical localization zones for pinpointing individual and multiple metal targets. The optional integrated Correctional Profiling System enables NIJ-compliant screening of people with or without implanted metal objects, ignoring profiled non-removable medical implants while detecting target threats.
A full-height light bar and multi-zone display provide precise threat identification. With exceptional immunity to external interference, the SMD601 PLUS maintains high discrimination and transit flow rates five times greater than those of other metal detection systems, achieving reset times as short as 0.2 seconds and detection speeds up to 50 ft/sec. The IP66-certified antivandal control unit ensures unmatched reliability with no periodic recalibration or scheduled maintenance required.

Fast-Track Security: High-Throughput Detection with MI2 Technology
The MI2 sensor is a multi-sensor technology, specifically an 18-axis passive magnetometer, integrated into Walk-Through Metal Detectors (WTMD). This technology combines the ability to detect metallic weapons (including magnetic and non-magnetic weapons and items made of light alloys) with the specific capability to identify mobile devices, including standard and miniaturized cellphones or smartphones with low metal content
The purpose of the MI2 sensor is to optimize security in high-traffic environments, such as correctional facilities, data centers, and corporate meeting rooms. By distinguishing between different types of threats, the system provides specific optical and acoustic signaling (red for weapons and yellow for cell phones). This allows security personnel to immediately identify the type of object detected, facilitating more efficient screenings, better management of access restrictions, and improved prevention of electronic device theft.

Specifications
Most Sensitive NIJ Certification
The SMD601 PLUS walk-through metal detector complies with NIJ-0601.02 and NIJ-0601.03 standards, demonstrating the ability to detect extremely small metallic threats defined in modern correctional security requirements. The system supports three security levels, plus ultra-high sensitivity, for detecting items such as disposable razor blades, bullets, and AISI 300-series stainless steel objects.
Medical Implant Profiling
The optional Correctional Profiling System enables NIJ-compliant screening for people with implanted metal objects. When a profiled user scans their badge, the detector ignores registered non-removable metal while still detecting and locating any new metallic threats, allowing accurate screening without nuisance alarms.
Full-Height Light Bar Localization
A full-height light bar with 20 vertical localization zones identifies threats anywhere on the body, from shoe level to the crossbar. Clear zone indication enables precise threat location, reducing manual searches and allowing efficient targeted secondary screening.
Smallest Threat Detection
Detects low-dimensional metallic threats, including disposable razor blades, bullets, and AISI 300-series stainless steel items. Provides accurate full-body screening from shoe level to crossbar with strong immunity to external interference and precise identification of individual or multiple metal targets.
Comprehensive Programs
Over 40 built-in security programs, including up to 22 pre-programmed security programs and up to 20 user-programmable custom levels. Chip card configuration enables fast, secure management of security levels. Met-Identity technology provides separate ferrous and non-ferrous alarm signaling. Password-protected access with user and super-user levels. Pre-programmed NIJ levels simplify compliance deployment.
IP66 Antivandal Construction
High-protection mechanical structure features an IP66-certified waterproof and dustproof housing (IEC 60529). Durable polymer construction resists impact, corrosion, and weather, while antivandalic and antitampering design protects against damage. Washable panels and enhanced display materials improve durability and LED visibility.
Automatic Setup
One Touch Self Installation (OTS) provides automatic guided setup. System includes Automatic Operational Functional Verification (OFV), Automatic Vibration Compensation (AVS/EVA), Automatic Channel Search (CS), Automatic Floor Gain Adjustment (FGA), Automatic Technical Functional Verification (TFV), and Automatic Environmental Noise Compensation (ENA). One-touch key reading of inbound, outbound, and security level data. Continuous self-diagnostic system ensures proven reliability.
Traffic Analytics
High precision bidirectional transit counter tracks in-bound transits, out-bound transits, and alarm rate. Provides detailed operational metrics for security management, staffing optimization, and compliance reporting. Essential for correctional facilities requiring documentation of screening operations and performance monitoring.
