Banner Engineering SI-MAGB2MM Magnetic Safety Switch

Description:

The Banner SI-MAGB2MM Magnetic Safety Switch is used in machine safeguarding systems to monitor the position of safety doors, guards, gates, and access panels in industrial equipment. Commonly installed in packaging machinery, robotic cells, conveyors, and automated production equipment requiring non-contact safety interlocking. Maintenance teams, OEM machine builders, and system integrators use this switch for machine safety upgrades, replacement of worn interlock devices, and compliance with industrial safety standards. The coded magnetic design helps reduce the risk of intentional defeat while providing reliable non-contact operation.

Applications:

The Banner SI-MAGB2MM magnetic safety switch is commonly used in machine guarding systems, access doors, safety gates, removable panels, and hazardous area enclosures where machine motion must stop when a guard is opened or removed. The non-contact magnetic design tolerates misalignment and contamination better than mechanical safety switches, making it suitable for washdown environments and high-cycle industrial applications.
