TUNNEL SEARCH COILS
Focused Vision for Ultimate Product Safety
Sesotec tunnel metal detectors reliably identify both magnetic and non-magnetic metal contaminants in bulk and piece goods. With single, dual, multi, or multi-simultaneous frequency technology, they are optimized for a wide range of applications—from trusted standard solutions to AI-powered high-end systems.
Who Benefits from Tunnel Metal Detectors?
A tunnel metal detector is essential for reliably detecting and eliminating both magnetic and non-magnetic metal contaminants in bulk and packaged goods. This ensures quality assurance and compliance with safety standards like BRC, IFS, and HACCP.
Primarily designed for the food industry, including baked goods, meat and dairy products, confectionery, ready meals, and cereal products. They are also used in the packaging, pharmaceutical, and plastics industries for quality control and product safety.
Our tunnel metal detectors identify even the tiniest, invisible metal particles regardless of material density or shape. Compared to X-ray systems, they are more cost-effective, require less maintenance, and are easier to operate.

- Iron
- Steel
- Stainless Steel
- Non-Ferrous Metals
Common foreign bodies made of iron include machine parts, screws, nails, wires, or wear from conveyor belts and production equipment.
Food products can contain production residues like shavings, screws, or broken tools from mechanical processing.
Stainless steel often enters production through worn or damaged machine parts, pipelines, or cutting tools.
Aluminum, copper, or brass often come from packaging materials, cable scraps, piping, or worn machine parts.
