Magnasphere MSS-63S 2.5" Surface Mount Contact Open Loop with 12" Leads, Universal Mounting, Brown, 10-Pack

Dependable intrusion detection for busy commercial and residential installations is the core benefit of the Magnasphere MSS-63S surface mount magnetic contact. This Magnasphere magnetic contact replaces fragile reed switches with award-winning non-reed switch technology to provide durable, consistent security monitoring for doors and windows. The compact 2.5" surface-mount housing and universal mounting make it ideal for retrofits, while 12" wire leads simplify wiring to alarm panels and access control devices. With an open-loop (N.O.) contact, a standard 0.5" gap and low power consumption, the MSS-63S integrates seamlessly into alarm systems, surveillance setups and remote monitoring applications. Tamper-resistant construction reduces false alarms and long-term maintenance, and UL/CE/TAA certifications back its use in commercial and government projects. Sold as a 10-pack for efficient deployment, each unit includes a 1-year limited warranty for installer confidence. For reliable door/window monitoring that stands up to real-world use, choose the Magnasphere MSS-63S — ideal for security contractors, system integrators and facility managers.
