The 2840T series magnetic contacts are designed for high-security hazardous environments. The rugged die-cast aluminum housing with conduit fittings meets UL requirements for hazardous locations.

The terminals are located inside the housing, providing additional protection from tampering or accidental shorting. A wider gap model protects against false alarms due to loose-fitting doors and permits faster installation.
