Welding positioning magnet WL1625

Overview
An electric magnet holder is an electromagnetic device for holding, positioning and releasing ferromagnetic parts by a controlled magnetic field. Activated by an electrical coil, it provides switchable magnetic force for flexible automation and precise part handling in industrial environments.

Electromagnetic holder Description
The WL1625 consists of a coil winding, magnetic core and carbon-steel housing with electrical leads and screw-mount holes. When energized the coil generates a magnetic field concentrated by the core to produce an attractive force; removing power releases the held part. Units may include connectors or feedback for integration with control systems.

How it works
The device operates on basic electromagnetism: current through the coil creates a magnetic field amplified by the core. Key factors affecting holding force include:

• Coil design and winding
• Core material and geometry
• Applied voltage and current
• Air gap between holder and workpiece
• Contact surface area and part geometry
