        abstract = {Efficient metal separation is a critical process in industries such as recycling, manufacturing, packaging, and material handling. The presence of unwanted metallic particles can damage machinery, compromise product quality, and pose safety hazards. Traditional manual sorting methods are time-consuming, costly, and prone to human error, highlighting the need for an automated solution
This paper presents the design and implementation of an Automatic Metal Separation System utilizing a Programmable Logic Controller (PLC). The system employs a conveyor belt to transport mixed materials, a photoelectric sensor for object detection, and an inductive proximity sensor for identifying metallic items. The PLC continuously monitors sensor inputs and controls the separation mechanism. Upon detecting a metal object, the PLC actuates a solenoid-controlled pneumatic cylinder, diverting the metal item into a designated collection bin, while non-metal objects continue along the conveyor uninterrupted.},
