Metal Detector Parameter JZ-M300

Keypack Intelligent JZ-M300 Digital All-Metal Detector is an inline conveyor-based metal detection system engineered for automated production lines requiring reliable foreign body identification. It delivers high-sensitivity detection — Fe ≥ φ0.8mm, Non-Fe ≥ φ1.2mm, SUS304 ≥ φ2.0mm — with a full SUS304 stainless steel frame, FDA-certified food-grade PU belt, and IP65 protection. Ideal for food processing, pharmaceutical manufacturing, cosmetic production, and textile quality control operations.

Product Overview

The Keypack Intelligent (kunbupack) JZ-M300 is a digital all-metal detection system designed to identify ferrous, non-ferrous, and stainless steel contaminants on high-speed conveyor lines. Built on advanced Digital Signal Processing (DSP) technology, the system features automatic product-effect compensation — a critical capability when inspecting materials such as sugar, salt, and meat products that naturally generate metal-like signals. The auto-learning function allows the detector to quickly acquire the optimal detection phase without manual calibration, reducing setup time and operator dependency.

The detection aperture measures 300mm (W) × 100mm (H), supporting a delivery capacity of up to 10kg per pass at a maximum belt speed of 25m/min. The belt height is set at 750 ± 50mm and can be customized to match existing line configurations. The probe is filled with epoxy resin to ensure long-term stability and extended service life in demanding production environments. The entire frame is manufactured using SUS304 stainless steel laser cutting, welding, and wire-drawing processes, meeting food machinery hygiene standards.

The LED flat key input display supports up to 12 product information storage presets, enabling fast changeover between product types. Parameter settings are password-protected, ensuring only authorized personnel can modify detection configurations. The system operates on AC 220V, 50–60Hz and carries IP65 ingress protection, making it suitable for washdown environments.

Key Features and Machine Characteristics

• Automatic Product-Effect Compensation: DSP-based auto-learning reduces false triggers caused by conductive products such as salt, sugar, and fresh meat — improving detection accuracy without manual phase adjustment.
• Auto Phase Tracking: The system automatically identifies product characteristics and calculates the optimal detection phase via digital chip processing, enabling fast and reliable setup across product changeovers.
• 12-Group Product Memory: Stores up to 12 product detection profiles, supporting efficient multi-SKU production lines with minimal reconfiguration time.
• Digital Sensitivity Control: Offers both digital sensitivity adjustment and a range of manual setting options to accommodate varying material types and detection sensitivity requirements.
• FDA-Certified Food-Grade PU Belt: The conveyor belt has passed FDA food-grade certification, providing enhanced resistance to contamination and facilitating hygienic cleaning and maintenance.
• Epoxy Resin-Filled Probe: The detection probe is encapsulated in epoxy resin, protecting internal components from vibration, moisture, and environmental interference to extend equipment service life.
• SUS304 Full-Frame Construction: Manufactured using laser cutting, welding, and wire-drawing processes in compliance with food machinery design standards — corrosion-resistant and easy to clean.
• IP65 Ingress Protection: Rated IP65 for dust-tight and water-jet resistance, suitable for washdown production environments in food and pharmaceutical facilities.
• European & American Safety Standards: Designed in accordance with European and American food machinery safety requirements, supporting integration into international production line inspection systems.
• Flexible Alarm & Rejection Options: Configurable alarm modes include alarm shutdown, buzzer alert, or an optional automatic rejection mechanism to suit different line layouts and compliance requirements.

Application Areas

• Food Processing: Inline metal detection for packaged meat, poultry, seafood, dairy, baked goods, confectionery, sugar, salt, and dry ingredients on conveyor production lines — including detection of fine metal particles embedded within product.
• Pharmaceutical Manufacturing: Foreign body inspection for tablet, capsule, and powder products during automated packaging and conveying processes, supporting GMP compliance requirements.
• Cosmetics Production: Detection of metal contaminants in cream, powder, and liquid cosmetic products prior to final packaging.
• Textile & Apparel: Identification of broken needles and metal fragments in fabric, garments, and stuffed products on end-of-line conveyor inspection systems.
• Toy & Hardware Manufacturing: Inline quality control for metal foreign body detection in assembled components and finished goods.
• Chemical & Industrial Products: Metal contaminant screening for granular, powder, and bulk industrial materials during conveying and packaging operations.
• Logistics & Distribution: Integration into automated logistics conveyor systems for foreign body screening prior to shipment or warehouse entry.
