GERMANY – Global inspection technology company METTLER TOLEDO is showcasing its newly launched M50 R-Series AdvancedLine metal detectors at Interpack 2026, as food manufacturers continue seeking inspection systems capable of improving traceability, compliance monitoring, and production line efficiency.
The launch comes during Interpack 2026 in Düsseldorf, Germany, where the company is also presenting its X56 DXD+ dual-energy photon-counting x-ray inspection system for packaged food applications.
Designed for modern food production environments, the M50 R-Series combines AI-based machine learning, advanced software algorithms, and digital connectivity tools intended to improve contamination detection while reducing unnecessary product rejects.
Food manufacturers face increasing traceability demands
Food manufacturers are operating under growing pressure to improve audit readiness, maintain digital records, and strengthen product traceability across increasingly automated production systems.
METTLER TOLEDO said the M50 R-Series was developed to address these operational changes, where inspection systems are expected to do more than detect contaminants. Manufacturers are also seeking systems capable of supporting data integration, production monitoring, and compliance reporting.
“The launch of the M50 R-Series reflects how closely we have listened to our customers,” said Jaison Anand, Market Manager – Metal Detection at METTLER TOLEDO Product Inspection.
“As production lines become faster and more complex, maintaining that balance becomes even more challenging.”
The M50 platform introduces technologies such as eDrive PLUS combined with a 900 kHz frequency to improve sensitivity for detecting smaller wire fragments and irregularly shaped metal contaminants.
The systems also use AI-supported 3S PLUS algorithms designed to adapt to different product characteristics and reduce false rejects during inspection.
Different models for different production conditions
The M50 R-Series includes several configurations tailored to different food manufacturing environments.
The M55R model is designed for dry products including pasta, snacks, and frozen foods. The M55RB targets bulk applications such as sacks, cartons, and powder products, using shielding systems intended to reduce radio frequency interference in larger production environments.
Meanwhile, the M56R is designed for more challenging applications involving chilled, wet, thawing, frozen, and metalized film-wrapped products, where moisture and packaging materials can interfere with conventional metal detection systems.
According to the company, the M56R combines multiple simultaneous frequencies with machine learning capabilities to improve inspection performance across these variable conditions.
Automation and data connectivity
Alongside contamination detection, the M50 R-Series introduces features aimed at reducing manual processes on production lines.
The systems include a 10.1-inch touchscreen interface designed for operation even with wet hands or gloves.
The platform also incorporates the INFINITY Electronic Test System, which automates inspection testing routines. METTLER TOLEDO said automated testing can reduce testing time by up to three times compared to manual inspection procedures.
Built-in Wi-Fi connectivity, QR code access, and communication protocols such as OPC-UA and EtherNet/IP are intended to support integration with manufacturing execution systems and centralized monitoring platforms.
The systems can also connect with METTLER TOLEDO’s ProdX software, which records inspection activities and stores compliance-related production data for audit purposes.
The company said the systems were developed to support alignment with food safety certification programs including BRCGS and International Featured Standards.
X56 DXD+ targets complex packaged products
Alongside the M50 launch, METTLER TOLEDO Product Inspection is also presenting the X56 DXD+ dual-energy photon-counting x-ray inspection system.
The platform is designed for packaged food products where detecting low-density contaminants such as rubber, plastic, and wood can be more difficult due to overlapping textures and varying product densities.
According to the company, the system combines dual-energy photon-counting detector technology with AMD Pro software to improve contamination detection in applications including pet food, potato chips, and larger packaged products.
The X56 DXD+ also supports seal inspection, clip detection, completeness checks, and product integrity verification during high-speed production. The company said the system can operate at speeds of up to 500 products per minute.
The platform is available in single-lane and multi-lane configurations and integrates with centralized monitoring and traceability systems through ProdX software.
Inspection systems expand beyond contamination detection
Inspection technologies across the food industry are increasingly integrating AI-supported analytics, automated testing, and digital traceability functions as manufacturers seek more centralized oversight of production and compliance activities.
Manufacturers are also facing growing expectations from retailers, export markets, and certification programs requiring detailed production records and documented inspection controls.
METTLER TOLEDO said the M50 R-Series was developed as part of broader investment in connected inspection technologies designed to adapt to changing operational and regulatory requirements.
