Working Principle and Applications of Metal Single/Dual-Sheet Detection Sensors

Metal double-sheet detection sensors are widely used in industrial production and automation to intelligently identify whether metal sheets are single or overlapped. These sensors provide reliable single/dual-sheet detection in many industrial processes.

These sensors use magnetic induction: they generate a magnetic field and detect changes when a metal object approaches, enabling single/dual-sheet recognition.

Applications for dual-sheet detectors include automotive, auto parts, metal coating, can making, printing, metal packaging, home appliances, hardware stamping, robotic pick-and-place systems, and lithium battery stacking, tab welding, PCB blanking, and board loading equipment. They are commonly used on automated stamping lines to ensure robots pick single sheets and avoid overlapped sheets entering the press, which would damage dies and waste material.

Dual-sheet detectors play an important role in industrial automation, helping enterprises achieve automated control and improve production efficiency and product quality. As technology advances, applications for dual-sheet detectors will expand and bring more benefits to industry.

Atonm Technology follows the mission of "empowering smart manufacturing with sensor technology" and focuses on industrial sensor R&D. We have developed a series of metal double-sheet detectors, and this year released several single-sensor dual-sheet detectors, including a two-channel single-sensor model compatible with both ferromagnetic and non-ferromagnetic materials (9000S) and a ferromagnetic two-channel single-sensor model (8200S). Both products target high-end imported brands, offering industry-level stability and reliability, and have been validated in the automotive sector.
