Lock Metal Detector

Applications & Use Cases

• Detecting ferrous, non-ferrous, and stainless steel contaminants in packaged food products.
• Ensuring product safety and compliance with food industry standards prior to dispatch.
• Protecting downstream processing equipment from potential damage caused by metal foreign bodies.
• Quality control checkpoint for baked goods, confectionery, meat products, and ready meals.

Typical Specifications

Typical throughput

Varies significantly based on product size, speed, and sensitivity settings; commonly processes hundreds to thousands of items per hour.

Power supply

Typically 3-phase, 400V, 50Hz, requiring a dedicated industrial electrical connection.

Construction material

Units of this type are almost exclusively constructed from stainless steel for hygiene and durability in food environments.

Operating environment

Designed for use in food production facilities, often with IP ratings suitable for washdown procedures.

Detection sensitivity

Commonly adjustable to detect metal spheres from approximately 0.8mm (ferrous) to 2.0mm (non-ferrous/stainless steel), depending on product effect.

Rejection mechanism

Often integrated with an automatic rejection system (e.g., air blast, pusher, or retracting belt) to remove contaminated products.
