Briefing
The Electromagnetic Safety Switch is a high-reliability safety interlock device designed for industrial doors, protective guards, and automated equipment. Featuring strong electromagnetic locking technology, it ensures stable and secure door monitoring to prevent unauthorized or accidental access during machine operation.
With its compact planar design, high-brightness LED status indicators, and dual-channel safety outputs, the switch provides excellent visibility, flexible installation, and enhanced operational safety. It supports both PNP and NPN outputs, as well as general and unique coding options, making it suitable for a wide range of industrial automation and machine safety applications.
Engineered for durability and precision, the switch can tolerate installation deviations and effectively prevents doors from remaining half-open, ensuring reliable protection and compliance with modern machine safety requirements.
