Jumbo Magnetic Reed Switch Surface Mount Wired - NO

The Jumbo Magnetic Reed Switch (Surface Mount, NO) is a heavy-duty, oversized magnetic contact sensor designed for securing large industrial doors, shutters, gates, and warehouses. With its robust metal housing and extended sensing gap, it is built to withstand harsh environments while providing reliable intrusion detection. This model is Normally Open (NO) – the circuit remains open when the magnet and switch are aligned, and closes when the magnet moves away, triggering an alarm or control signal.
