Reliable pallet sensors for stable automated production
Ferrum Group helps industrial producers keep automated lines running smoothly by eliminating a common hidden cause of downtime: inconsistent pallet quality. Our pallet sensors are part of robust pallet inspection and sorting solutions built on solid engineering, proven industrial components, and innovative automation design. When pallets move fast and continuously through your plant, you need consistent, measurable checks—rather than manual assessments that vary from shift to shift.
We combine industrial robotics, controls engineering, and advanced vision technology to deliver reliable decisions at production speed. This is especially valuable for returnable pallets where wear, moisture, or impact damage can silently disrupt conveyors, palletizers, depalletizers, and infeed systems—often before the root cause is visible to operators.
From manual checks to data-driven pallet quality control
Pallet flow becomes a competitive advantage when inspection is automated, traceable, and repeatable. With Ferrum Group, pallet sensors are implemented as part of a complete concept—from mechanical design and safety guarding to PLC control, HMI, and integration with your existing material handling and production technology.
Our goal is to replace labor-intensive sorting with an automated pallet inspection setup that matches your real operating conditions: cycle times, pallet variants, hygiene requirements, and quality thresholds. Using pallet sensors in a structured inspection flow helps protect uptime and reduce quality-related disruptions—without adding unnecessary complexity for operators or maintenance teams.
Typical outcomes include:
- Fewer unplanned stops caused by damaged, skewed, or misaligned pallets
- Consistent acceptance and rejection based on configurable criteria
- Reduced manual handling, forklift traffic, and operator variability
- Improved transparency through reporting, statistics, and optional ERP/MES integration
We also design solutions that can evolve with your production—adding additional pallet sensors, supporting new pallet types (including EUR and EPAL formats), or expanding sorting categories without rebuilding the entire line.
How our pallet inspection systems work in practice
We deliver pallet handling automation where pallets are moved, positioned, and presented correctly for scanning and classification. The quality decision depends on stable mechanics and controlled motion just as much as sensors and software—so we engineer the system as one integrated unit.
A typical solution combines conveyors and robotic handling with pallet scanning using 2D/3D technologies. Depending on your requirements, we implement pallet sensors based on:
- 2D vision systems for camera-based pallet inspection and surface checks
- 3D scanning for geometry validation, deformation detection, and defect identification
- Industrial scanner platforms such as SICK 3D laser scanning or the SICK TriSpector 3D scanner (selected and validated to match your throughput and pallet variants)
Where relevant, we also add moisture detection for damp pallet identification and weighing for pallet weight control or anomaly detection—ensuring your pallet sensors support both quality assurance and operational reliability.
Key inspection capabilities can include:
- Pallet defect detection, including missing boards, missing blocks, defective boards, holes in boards, rotated blocks, or protruding nails
- Dimensional checks and planarity verification for stable transport in automated lines
- Pallet moisture detection and pallet discoloration or pallet colour detection (when relevant to your process and acceptance criteria)
- Automated sorting to approved/rejected lanes—or multiple quality grades for rework and reuse strategies
Controls and usability are designed for industrial reality, typically with PLC control (including Siemens S7 PLC) and a clear HMI operator panel. This enables fast recipe changes, adjustable tolerances, and efficient alarm handling—while pallet sensors deliver consistent decisions at line speed and generate the data needed for continuous improvement.
Engineered for high capacity, integration, and measurable results
Many of our customers run high-throughput plants where small inefficiencies quickly become expensive. That is why we focus on high-capacity, stable automated pallet inspection that keeps pace with production—supported by the right mechanics, controls, and pallet sensors. We design pallet sorting system layouts to match your footprint and operational needs, from compact inspection cells to fully integrated pallet control systems across multiple infeed points.
Beyond detection, our solutions support action: reject handling, rework loops, and add-on modules such as nail press stations or brush sections when your operation requires it. The result is a solution that reduces stoppages, protects critical equipment, and strengthens overall equipment effectiveness (OEE) through repeatable pallet quality control.
