SCHMERSAL Magnetic Safety Switch BPS250 Key benefits Protects people and equipment: the BPS250 is a magnetic safety switch designed to reliably monitor access points and stop hazardous motion when a guard or door is opened. Non-contact operation reduces wear: magnetic actuation provides contactless sensing for long service life and low maintenance. Reliable integration: connects with safety control circuits to deliver predictable, safety-rated switching performance for industrial applications. Simple installation and operation: compact design and straightforward mounting reduce installation time and simplify machine safety upgrades. What it does (function) Acts as a safety interlock switch using magnetic actuation to detect the position of guards, doors, or removable covers. Provides a safety signal to a machine’s control system whenever an access point is opened, supporting safe shutdown or prevention of hazardous motion. Compatibility and system fit Designed to integrate with standard safety relays and controllers used in industrial automation. Works with typical guard and door assemblies where a magnetic, non-contact interlock is preferred. Compatible with Schmersal safety accessory ranges and mounting options, enabling straightforward replacement or system expansion. Durability, size, and materials Built for industrial environments, with a robust housing that resists mechanical stress and everyday factory conditions. Compact footprint supports installation in confined spaces; non-contact operation minimizes mechanical wear points for extended life. Constructed from materials appropriate for reliable operation in typical machine-safety applications. Performance highlights Consistent magnetic switching ensures dependable detection of guard or door position. Low maintenance due to contactless design and rugged construction. Designed to contribute to reliable, repeatable safety behavior in production and automation systems. Typical applications / use scenarios Machine guarding: Monitor the position of hinged or sliding guards on presses, cutters, and forming machines so the machine cannot run while a guard is open. Conveyor and material handling systems: Protect access points and maintenance doors along conveyors to prevent accidental exposure to moving parts. Robot cells and automated workstations: Secure cell doors and access ports, enabling safe entry procedures and controlled restarting of operations.
