R-4 Electromagnetic Strike 12V with Memory Symmetrical Aluminum 89/336/EEC

Product Overview

The R-4 electromagnetic strike (12V with memory) is engineered for access control in gates, double doors, and intercom systems, suitable for installation in areas requiring durable locking mechanisms, such as residential and commercial entryways. Constructed from corrosion-resistant aluminum alloys and powder-coated for enhanced surface protection, this strike is compliant with the 89/336/EEC directive, ensuring electromagnetic compatibility for professional use.

Its distinguishing feature is the integrated memory function, which maintains the unlocked state until the door is physically opened, simplifying integration into intercom and access control systems where delayed unlocking is required. The R-4's compact and symmetrical design facilitates flexible installation on both left- and right-hand doors, making it particularly suited for bulk procurement by contractors working on mixed-entry projects or retrofit upgrades in multi-tenant buildings.
