Primary Application
Large conveyors. Continuous material flow. Integrated metal detection.
The detector is intended for bulk-handling installations where large quantities of material move continuously and at considerable belt speed. It gives turnkey EPC contractors and system integrators a configurable electronics platform that can be engineered into the conveyor, control panel and plant sequence.

Designed Around EPC Project Requirements
- Suitable for new conveyor packages and detector retrofit projects.
- Supports large-aperture search-coil arrangements subject to application validation.
- Healthy, direct and timed relay outputs for PLC, alarm, belt-stop or downstream action.
- Configurable sensitivity and timing for the operating sequence and conveyor conditions.
- Diagnostic screens simplify commissioning, tuning and field troubleshooting.
- EIB support for coil matching, electronics, panel integration, wiring and validation.
For EPCs, OEMs & Machine Builders
Detector electronics designed for practical integration.
The system separates the detector electronics and door-mounted display into two connected assemblies, giving project engineers freedom to design the search-coil structure, metal enclosure, cable routing and operator interface around the conveyor package.
Detector and I/O Control PCBRetrofit-Oriented Connections
Physical dimensions and external terminal numbering support replacement of an existing detector system. Search-coil wiring can remain consistent, subject to application-specific tuning changes.
Metal-Enclosure Installation
The detector electronics are intended for installation in a protective metal enclosure with suitable space, conduit entries and cable management for search coils and machine wiring.
Commissioning Support
Factory and field settings combine onboard tuning with display-based configuration. EIB can support coil matching, integration checks and onsite commissioning.
Operator Experience
Clear status, controlled access and useful diagnostics.
The 4-line display guides normal operation, configuration and troubleshooting without requiring a separate computer.
Automatic Startup Check
At power-up the system checks the internal oscillator, transmitter feedback, transmitter output and tuning, and receiver-coil connection before normal operation.
Live Detection Status
The running screen presents ferrous amplitude, non-ferrous amplitude, programmed detection level and current system status.
Protected Configuration
Password-controlled editing provides access to 1–99% sensitivity, direct-output timing, delayed-output timing, rejection duration and master detection-counter reset.
Signal-Level Diagnostics
A diagnostic screen displays transmitter output, ferrous and non-ferrous receiver levels, and feedback amplitude against commissioning thresholds.

* Manual reference condition: approximately 45 cm vertical spacing between transmitter and receiver coils. Application performance must be validated with the actual aperture, conveyor, product and contaminant samples.
Installation & Commissioning
Critical field requirements for reliable detection.
Detection performance depends on coil geometry, correct tuning, cable quality, earthing and the surrounding electrical environment. Final commissioning must be performed on the installed conveyor.
Coil Cable
Keep the electronics cabinet within 100 m of the search coil and use 50 Ω coaxial cable with at least 100% shielding, following the approved cable specification.
Electrical Clearance
Locate motors, magnets and other inductive electrical or electronic loads at least 15 m from the detector coils wherever the installation permits.
Dedicated Earthing
Earth the metal detector cabinet using a star connection. The system 0 V reference is bonded to earth; do not loop other equipment through this connection.
Commissioning Levels
Use the diagnostic screen to verify transmitter output above 12 V RMS, AF and ANF receiver levels above 400 mV, and feedback above 1 V.
Application Engineering
Integrate the detector into your machine—not around it.
EIB Solutions can adapt the electronics and support the complete integration path for new machines or retrofit projects.
- Search-coil and tuning support
- Panel, display cut-out and wiring guidance
