Magnasphere HS-L1.5 UL634 Level High Security Single Alarm, Surface Mount Contact, Closed Loop with Pry Tamper Closed Loop

Built for high-security environments, the Magnasphere HS-L1.5 UL634 magnetic contact delivers dependable tamper detection for safes, vaults, cabinets and data center doors. The HS-L1.5-101 Magnetic Contact uses Magnasphere's solid-state switch technology (not a reed switch), providing a robust closed-loop (N.C.) alarm circuit that resists nuisance failures and ensures continuous surveillance and monitoring. Certified to UL-634 Level 1 standards, it supports up to 30V DC operation with low power draw (250 mW) and a standard gap of 0.25" for precise intrusion sensing.

Designed for commercial installation, this surface-mount contact requires no brackets or adjustment, reducing install time and labor costs. The integrated pry tamper protects against forced entry attempts while color-coded wire leads simplify integration with access control, alarm panels and security monitoring systems. Constructed in aluminum and TAA compliant, the HS-L1.5 is ideal for critical applications where reliability and compliance matter.
