Hager 2-679-0625 Concealed Magnetic Contact — Aluminum Finish Door Position Sensor

The Hager 2-679-0625 is a concealed magnetic door-position contact finished in aluminum (ALM) designed to report door open/closed status to access-control panels, alarm systems, and building management systems. This type of device is commonly referred to as a door position sensor (DPS) or magnetic door contact — a reed-switch-based assembly that mounts discreetly within the door and frame to provide continuous door-state monitoring without exposed hardware. It is an essential component in any monitored or access-controlled opening in commercial, institutional, or government facilities.

Key Features & Benefits

• Concealed Installation: The contact assembly mounts within the door edge and frame, keeping the sensing hardware hidden from view — ideal for architecturally sensitive or high-security openings.
• Reed-Switch Technology: Uses a proven magnetic reed-switch mechanism to deliver reliable open/closed door-state signals to connected access-control or alarm systems.
• Door Position Monitoring (DPS): Provides real-time door-state feedback — a code and best-practice requirement on monitored openings, fire-alarm-integrated doors, and access-controlled entries.
• Aluminum (ALM) Finish: Durable aluminum-finish housing coordinates with standard commercial door hardware finishes and resists the wear of high-cycle commercial openings.
• Access-Control Integration: Designed for use with standard access-control panels and security monitoring systems requiring a normally open (NO) or normally closed (NC) dry-contact door-state input.
• Commercial & Institutional Grade: Engineered for demanding commercial, government, healthcare, and educational facility applications where reliable door monitoring is critical.

Typical Applications

• Access-controlled entries in offices, healthcare facilities, schools, and government buildings
• Monitored door openings integrated with fire alarm or building management systems
• Security-sensitive openings requiring continuous door-state reporting
• Electrified hardware assemblies where door position feedback is required by the access-control panel
