Magnasphere HSS-L2D UL634 Level High Security Dual Alarm, Surface Mount Contact with Conduit Fitting

Protect critical areas with a purpose-built contact that meets the demands of high-security installations. The Magnasphere HSS-L2D magnetic contact is engineered for SCIFs, safes, vaults and other environments where tamper resistance and reliable monitoring are mandatory. As an UL 634 Level 2 device, it delivers certified intrusion detection performance and resists both internal and external magnetic defeat attempts. Built on Magnasphere’s proven switch technology (not a reed switch), the L2D offers long-term reliability and won’t fuse, reducing false alarms and maintenance costs.

Installation is simplified and hardened with dual 1/2" NPT conduit ports for top or side entry and optional armored cable lengths to protect wiring from physical attack. The surface-mount aluminum housing and a 0.13" standard gap provide precise contact supervision in a compact footprint. Ideal for integration with access control, surveillance and alarm monitoring systems, the L2D-800 supports closed-loop configurations for secure signaling. Specify UL-10C fire-classified or custom cable options for specialized applications. Add the Magnasphere HSS-L2D to your security design to strengthen intrusion detection — contact us to configure or order for your next high-security project.
