The Magnetic Reed Switch by Schmersal is engineered for contactless position detection in industrial and safety applications. It operates based on a magnetic field principle, where internal reed contacts are activated when a corresponding magnet comes within range, enabling or interrupting an electrical circuit.
These switches are widely used for monitoring safety guards, doors, flaps, and moving machine components, ensuring that machinery operates only when all safety conditions are satisfied.
Schmersal magnetic reed switches, such as the BN and EX-BN series, are designed for non-contact operation, eliminating mechanical wear and ensuring long service life. They are suitable for both standard industrial environments and explosion-hazard areas (ATEX Zones 2 and 22), making them ideal for critical safety applications.
With robust aluminium or thermoplastic housings, high protection ratings (up to IP67), and resistance to vibration and harsh environmental conditions, these switches provide dependable performance in demanding industrial environments.
Their compact design, flexible mounting options, and compatibility with safety relays and control systems make them a versatile solution for modern automation and machine safety systems.
