Dorma EM 1800 AH Electromagnetic Lock Surface-Mounted 1800N With Door Status Sensor

Product Overview

The Dorma EM 1800 AH surface-mounted electromagnetic lock is designed for secure access in multiple door types, including cabinets, showcases, drawers, and office doors. Commonly used in commercial environments and office buildings, it provides a holding force of 1800 N (180 kg) and is suitable for integration with access control systems, operating reliably in temperature ranges from -40°C to 60°C.

A key differentiator for the EM 1800 AH is its built-in door status sensor (NC/NO contacts), which communicates the open or closed state directly to access management systems. This feature eliminates the need for supplemental position sensors during installation, streamlining wiring and reducing system integration points. Recommended for access control integrators and facility managers seeking secure, monitored entry solutions and efficient installation for doors, lockers, or display cases.
