Technical Specifications

Detection sensitivity is validated per tunnel height. The 910K accepts fully customized tunnel dimensions, rejection types and storage capacity for your specific production line.

Sensitivity Matrix by Tunnel Height
Tunnel Height (mm) 100 120 150 200 250 300 350 400
Fe (φφmm) ≥0.8 ≥0.8 ≥1.0 ≥1.2 ≥1.5 ≥2.0 ≥3.0 ≥3.5
Non-Fe (φφmm) ≥1.2 ≥1.2 ≥1.5 ≥2.0 ≥2.5 ≥3.0 ≥3.8 ≥4.5
304 SUS (φφmm) ≥1.5 ≥1.5 ≥2.0 ≥2.5 ≥3.0 ≥3.5 ≥4.5 ≥5.0
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.

Newly Upgraded · Performance Enhancement

Six Reasons the 910K Outperforms

Every component is selected to keep your line running — precise detection, fewer false rejects and less operator intervention.

HD Sensitive Touch Screen

Intuitive 7-inch color interface. Set speed, modes and parameters directly on screen — no PC or specialist required.

Position the Metal Accurately

Precise signal processing pinpoints the contaminant position for clean, consistent rejection with minimal product loss.

Imported Infrared Sensor

Reliable triggering and counting. The reject system reacts precisely to every contaminated item passing the detection head.

Intelligent Imported Chips

Digital core developed with advanced technology and original imported chips. Sealed detection coil delivers stable, anti-interference performance.

Automated Self-Learning

Fully automatic learning — no manual product placement needed. Select auto-setting and obtain optimum sensitivity without tuning.

Stainless Steel Body

Advanced SUS304 construction resists rust and oxidation in humid production environments — built for daily washdown.

Core Engineering

The detection head and conveyor belt are the heart of the machine — engineered to hold sensitivity while your line runs at speed.

910K high precision detection head with touchscreen interface

High-Precision Detection Head

High-temperature 3.5 copper wire wound 360° around the aperture and sealed with resin in one pass. The result: stable sensitivity, strong anti-interference and long service life.

  • Resin one-time sealing — moisture and vibration proof
  • 360° copper coil surround for uniform field
  • Fe sensitivity from 0.8mm (100mm tunnel)
