Technical Specifications

Detection sensitivity is validated per tunnel height. The 806 adds a lifting mechanism for on-site height adjustment, plus fully customized tunnel dimensions and reject types for your specific production line.

Sensitivity Matrix by Tunnel Height
Tunnel Height (mm) 100 120 150 200 250 300 350
Fe (φmm) ≥0.8 ≥1.0 ≥1.2 ≥1.5 ≥2.0 ≥3.0 ≥3.5
Note: Sensitivity above is measured under empty-machine condition. Actual detection sensitivity is affected by product characteristics and environment, and varies with the position of the metal contaminant. Non-ferrous and stainless sensitivity available on request.

Newly Upgraded · Performance Enhancement

Six Reasons the 806 Outperforms

A lifting mechanism plus permanent magnet signal processing — one machine adapts to changing product heights while detection stays sharp.

On-Site Height Adjustment

Lifting mechanism raises or lowers the detection head to fit different product heights — no re-engineering when your product mix changes.

Digital Control Panel

Digital display with sensitivity and intensity indicators, auto / manual mode, counters and bilingual function keys — simple and efficient to operate.

Position the Metal Accurately

Real-time sensitivity and intensity indicators pinpoint contaminants clearly, so operators react fast and product loss stays minimal.

Permanent Magnet Core

Twin induction coils above and below the belt work with permanent magnet signal technology, holding high sensitivity and strong anti-interference through every height adjustment.

Foil-Smart Filtering

An intelligent magnetic induction system recognizes and passes qualified aluminum foil and non-ferrous film packaging automatically — no false rejects.

3mm Stainless Steel Body

Built with heavy 3mm stainless steel plate for rust resistance and oxidation protection in humid washdown plants — stable and good-looking for years.

Core Engineering

Every component of the 806 is engineered to keep sensitivity stable while your line runs at full speed.

Dual-Coil Detection Head

Twin coils mounted above and below the tunnel pair with permanent magnet signal processing, giving sharp sensitivity and solid anti-interference even as the head moves to a new height.

  • Upper & lower induction coil design
  • Permanent magnet signal processing
  • Fe sensitivity from 0.8mm (100mm tunnel)
806 lifting mechanism with guide rods and lead screw for height adjustment

Lifting Mechanism

Stainless guide rods paired with a lead screw raise or lower the detection head smoothly — adjust the tunnel height on site to match different product heights.

  • Stainless guide rod & lead screw design
  • On-site height adjustment without tools
  • Keeps sensitivity stable at every height

Product Details

Attention to every mechanical detail keeps the 806 stable in continuous operation and simple for your operators to maintain.

Mobile Frame & Leveling Feet

The 806 stands on a rugged stainless steel frame with red swivel casters and leveling feet — roll it into position and lock it level in minutes.

New Features

The upgraded 806 adds production-grade intelligence: lifting height adjustment, 0.8mm sensitivity and foil-smart filtering — standard on every unit.

01 · LIFTING

Height-Adjustable Tunnel

Lifting mechanism adjusts the detection head height on site — one machine handles different product heights without re-engineering.

02 · SENSITIVITY

0.8mm High Sensitivity

Fe sensitivity from 0.8mm on a 100mm tunnel — sharp detection for ferrous contaminants on every line.

03 · MAGNET

Permanent Magnet Processing

Upper and lower induction coils with permanent magnet signal processing give high sensitivity and strong anti-interference.

04 · FOIL

Foil-Pack Smart Filtering

Qualified packaging of aluminum foil and non-ferrous metal films passes automatically — no false rejects on foil-packed goods.

05 · COUNTERS

Batch Count & Traceability

Qualified / total / detected counters track every batch — meet audit and quality traceability requirements.

06 · CRAFT

Japanese & British Technology

Engineered with reference to leading Japanese and British designs — dependable performance, excellent value and fine manufacturing quality.

Where the 806 Works

Designed for detecting ferromagnetic metal impurities in products or raw materials — iron nails, iron wires, mesh screen fragments, fish hooks, screws, needle tips and metal tools.
