Product Overview
The standard Metal Detector(MD Series) features a robust and cleanable Stainless Steel 304 frame, powered by a precision Japanese Oriental Motor, with a Hardfill-coated metal detector head at the critical inspection point and U.S.-made FRAM memory for reliable data retention. All product-contact surfaces meet sanitary standards, including the food-grade PU conveyor belt and corrosion-resistant SUS 304 roller bearings. To meet higher performance demands, optional Japanese SMC pneumatic components and a Danish Danfoss frequency converter are available for enhanced energy efficiency and motion control.
Key Feature
This intelligent detection system is engineered for precision and ease of use in industrial environments. At its heart, a self-learning capability enables automatic parameter configuration, ensuring simple and quick setup for operators. The core processing unit achieves superior performance through a combination of advanced DDS (Direct Digital Synthesis) and DSP (Digital Signal Processing) technologies, which significantly enhance detection accuracy and signal stability.
To guarantee reliable operation amidst electrical noise, the system employs robust X-R orthogonal decomposition and multiple filtering algorithms, providing exceptional anti-interference performance. This is further reinforced by intelligent phase tracking and auto-balancing adaptive technology, which dynamically maintains optimal detection stability. For flexible integration, the unit features an optically isolated driver, allowing the control panel to be installed at a remote distance from the main machine without signal degradation.
Critical device settings are securely preserved using U.S.-made Ferroelectric RAM (FRAM), which offers non-volatile storage for up to 50 product parameters without data loss. Combined with a rigid structure built for durability, the system delivers consistent and sensitive detection of a wide range of metals, including iron, stainless steel, copper, aluminum, and lead.

In food production (e.g., meat products, baked goods, canned vegetables), the metal detector ensures product safety by identifying and rejecting metallic contaminants such as metal fragments from processing equipment or packaging. It is critical for preventing consumer harm and protecting brand reputation. This process directly supports compliance with mandatory food safety regulations and global standards like HACCP, FDA, and GFSI (BRC/SQF), providing essential documentation for audits and enhancing overall consumer trust.
For chemical and pharmaceutical products (e.g., powdered raw materials, tablets, fine chemicals), the metal detector safeguards product purity and process integrity by detecting fine metallic particles. It prevents contamination from equipment wear (e.g., mixer blades) or stray materials, which is crucial for product efficacy, equipment protection, and end-user safety. This critical control point aligns with stringent industry quality protocols such as cGMP, ensuring the reliability of the production batch and compliance with pharmacopeial standards.
To meet diverse production line needs, the system offers four specialized rejection solutions: the Air Jet Rejector is designed for high-speed, non-contact removal of lightweight items; the Air Pusher delivers a powerful mechanical push for heavy or stable products; the Drop Belt Rejector ensures absolute separation by opening its belt section, ideal for fragile or high-value goods; and the Flipper Rejector provides efficient and reliable sideway rejection with a compact pivoting action for various packaged items. The optimal choice can be made based on specific product characteristics (size, weight, fragility) and line layout requirements.
Yes, it can be customized per customers’ product size range, ensuring seamless alignment with existing production lines,rather than affecting the detection effect.
Optimal performance requires a working environment free of obvious vibration, as vibration may reduce metal detection sensitivity. It is recommended to install the system in a stable, low-interference area.
