Magnasphere HSS-L2S-003 Single Channel Temperature and Current 1K Ohm End of Life Resistor, Closed Series Embedded Resistor, Closed Loop Arm Circuit

Protect high-security areas with a compact, installer-friendly magnetic contact designed for mission-critical intrusion monitoring. The Magnasphere HSS-L2S-003 magnetic contact provides single-channel alarm detection with a closed-loop tamper circuit and an embedded 1KΩ end-of-life (EOL) resistor to simplify wiring and ensure reliable supervision. Built to meet UL634 Level 2 high-security standards, this sensor is ideal for SCIFs, safes, vaults and other environments where surveillance integrity is mandatory.

Beyond compliance, the HSS-L2S-003 is engineered to resist magnetic defeat and permanent contact welding from surges or tampering attempts, reducing maintenance and false positives. The surface-mount, cross-hole mounting design speeds installation and eliminates most bracket needs, while compatibility with standard control panels makes integration straightforward for security and monitoring teams. Whether you’re upgrading an existing intrusion detection system or specifying sensors for new high-security builds, the Magnasphere HSS-L2S-003 offers dependable performance and streamlined installation. Add it to your security architecture for enhanced monitoring — contact your supplier to order or request integration support.
