Magnetic switches detect changes in magnetic fields to determine object position without physical contact. In pneumatic cylinders, the piston contains a permanent magnet. As the piston moves, the switch senses magnetic field variations to identify position and output electrical signals. This contactless design enables fast response, eliminates mechanical wear, and delivers long service life.

Key Advantages

• Contactless durability:The no-contact design minimizes wear and aging, making it ideal for industrial equipment requiring high frequency and stability.
• Harsh environment adaptability: With IP67 protection rating, SAIER products maintain stable performance in wet, oily, and dusty conditions.
• Built-in safety:Short-circuit protection automatically disconnects during circuit abnormalities to prevent equipment damage.
• Robust construction:Industrial-grade materials provide impact resistance and extreme temperature tolerance (-25°C to +70°C) for demanding applications like metallurgy and chemical processing.
• Specialized solutions:offers weld-proof and explosion-proof models for welding zones and flammable environments.
• Precision control:Beyond standard switch outputs, analog versions provide continuous voltage/current signals based on magnetic intensity for complex control systems.

Primary Applications

Magnetic switches play vital roles in industrial automation:

• Cylinder piston position detection for synchronized equipment movement
• Precise material positioning in automated production lines
• Warehouse logistics equipment monitoring for improved efficiency and safety
• Machinery movement limitation to prevent overtravel and collisions
