Atonm Metal Double-Sheet Detector Single-Sensor Series: Small Size, Big Power—Precise Detection of Every Sheet

In industrial production, reliable single/double-sheet detection for metal plates is critical to line stability. Atonm introduces the Metal Double-Sheet Detector Single-Sensor series, offering compact design, precise detection and flexible integration for automotive, battery stacking and hardware industries.

Product positioning

The Single-Sensor series is a contact-type detector based on electromagnetic induction and eddy current principles, designed to distinguish single, double or missing sheets with high reliability. Key advantages include compact size, high detection speed and broad material compatibility.

• Compact form factor: large probe diameters 42–44mm (length 87.3–90mm) and small probes 12mm×35mm, suitable for robot end-effectors and tight spaces.

• High throughput: response up to 200 pcs/min for typical lines and up to 1200 pcs/min for battery stacking, enabling immediate detection during pick-and-place.

• Wide compatibility: supports magnetic and non-magnetic materials 0.01–4.0mm thick, including steel, iron, aluminum, copper and stainless steel, and is resilient to oil, coatings and air gaps.

Technical advantages

1. Data-driven modeling: trained on 170,000+ samples to build material, thickness and surface condition models combined with AI algorithms to achieve 99.9% double-sheet recognition accuracy in many scenarios.

2. Robust anti-interference: triple noise suppression (EM shielding + adaptive filtering + dynamic baseline compensation) maintains stable output under 50Hz mains interference and strong stray magnetic fields.

3. Smart connectivity: supports Profinet, Modbus and IO protocols for PLC and MES integration, enabling real-time alarms, data logging and cloud uploads for remote monitoring and process optimization.

Typical applications

• Automotive stamping: protects dies from double-sheet feeding and reduces maintenance costs.

• Battery stacking: micro-thin sheet detection prevents shorts and improves yield.

• Home appliance hardware: millisecond response intercepts double feeds, improving efficiency and reducing defects.

Selection guidance

Offers customizable options for special materials and conditions, with embedded or base-mounted installation variants.
