GRI 5065 Series 3/8" One-Inch Gap Recessed Contact

GRI 5065 Series 3/8" One-Inch Gap Recessed Contact

The GRI 5065 is a recessed magnetic reed switch contact designed for door and frame integration in access control and security systems. This component provides reliable door position detection in applications where concealed mounting and tight gap tolerances are required. The 5065 series accommodates 3/8-inch door gaps with a one-inch overall dimension, making it suitable for standard commercial door frames and retrofit installations.

Overview

Recessed contacts are fundamental to door control systems, providing real-time position feedback that integrates with access control panels, strike controllers, and monitoring systems. The GRI 5065 delivers consistent switching performance across typical building access environments. The recessed form factor allows installation directly into door frames or strike plates, minimizing visibility and creating a seamless aesthetic in high-traffic areas.

Key Features

• 3/8-inch door gap specification for standard commercial door frames
• One-inch overall dimension for compact recessed mounting
• Magnetic reed switch technology for reliable position detection
• Recessed installation profile reduces surface protrusion
• Compatible with standard strike plate and door frame cavities
• Consistent switching performance across temperature ranges typical of interior building environments
• Low-voltage operation suitable for access control circuit integration
• Durable contacts designed for extended cycle life in high-traffic applications

Integration & Compatibility

The GRI 5065 integrates into access control systems through standard door position circuits. It functions as a normally-open or normally-closed switch, depending on system configuration and magnet positioning. The recessed contact works with standard strike controllers, access control panels, and monitoring relay modules. Installation requires cavity preparation in the door frame and magnet placement on the door itself. This architecture is compatible with wired access control systems across residential, commercial, and institutional buildings.

Application Suitability

The 5065 is well-suited for applications requiring hidden or semi-concealed contacts, including executive offices, conference rooms, secure storage areas, and facilities where aesthetic integration is important. The 3/8-inch gap tolerance addresses the most common commercial door frame dimension. Integrators should verify exact cavity dimensions and magnet clearances during pre-installation assessment to ensure proper alignment and switching reliability.
