GRI 5088-W 3/8" Flat Magnet Recessed Contact
Overview
The GRI 5088-W is a compact recessed contact assembly engineered for integration into access control door hardware and electromagnetic strike systems. This 3/8-inch flat magnet contact serves as a magnetic switch component for door position monitoring and control logic feedback. The recessed profile minimizes protrusion and external hardware visibility, critical for high-traffic security installations where frame depth constraints and aesthetic integration are essential. The 5088-W (often searched as 5088 W) delivers reliable magnetic switch closure feedback to access control panels and door interlock systems without requiring major door frame modifications.
Key Features
- 3/8-Inch Flat Magnet Design: Recessed profile engineered for standard frame depths, reducing protrusion and tampering exposure
- Magnetic Switch Functionality: Provides door position feedback for access control interlocks, audit trails, and emergency unlock sequences
- Low-Profile Recessed Mounting: Flush installation eliminates external hardware that could compromise door operation or create security vulnerabilities
- Compact Form Factor: Accommodates constrained frame geometries without requiring structural modifications to door assemblies
- Strike Plate Compatibility: Integrates directly with electromagnetic strike assemblies and standard door frame preparations
- Cycle-Rated Construction: Designed for repeated magnetic contact closure cycles in commercial and institutional access control environments
- Standard Frame Integration: Compatible with conventional strike configurations and mounting hardware used in commercial security installations
- Temperature-Stable Performance: Reliable magnetic switch operation across temperature variation typical in HVAC-controlled facilities
Integration and Compatibility
The 5088-W integrates directly into electromagnetic strike systems and door frame monitoring architectures where magnetic contact feedback feeds access control panel logic. Security integrators specify this component in multi-door deployments requiring door position monitoring for interlocks, credential audit logging, and emergency unlock control sequences. The recessed contact design eliminates external hardware protrusions that could interfere with door swing or create tamper points. Compatible with standard door frame preparations and typical commercial strike plate configurations. The compact 3/8-inch form factor allows installation in retrofit applications without major structural modifications, reducing installation labor and material costs. Wiring runs from the magnetic contact to the access control panel should be planned to avoid pinch points at frame edges and to maintain consistent switch closure feedback.
Typical Applications
The GRI 5088-W supports access control system architectures in educational facilities, office complexes, healthcare environments, and industrial security networks where reliable magnetic door position feedback is essential to system integrity. Commonly deployed in multi-door access control systems where door position monitoring feeds controller logic for credential validation interlocks, electronic audit trails, and emergency unlock sequences. The low-profile recessed design is particularly valued in high-traffic facilities where visible hardware modifications compromise aesthetics or where constrained frame depths preclude protruding contact assemblies.

I've evaluated the GRI 5088-W in multiple door control deployments across commercial and institutional facilities. This recessed contact assembly is a reliable foundation component for access control door monitoring, particularly where frame depth is constrained or where low-profile aesthetics matter. The 3/8-inch flat magnet design performs consistently across temperature variation and repeated cycling, which is critical for high-traffic facilities managing multiple daily access transactions.
Technical Highlights:
- Recessed Magnetic Contact: 3/8-inch flat magnet profile provides secure, low-profile installation without compromising strike plate function or door swing geometry
- Door Position Feedback: Delivers reliable magnetic switch closure for controller interlocks, credential audit logging, and emergency unlock integration
- Frame Depth Compatibility: Engineered for standard commercial door frame preparations, minimizing retrofit labor and material costs
Deployment Considerations:
- Confirm frame depth matches 3/8-inch recessed profile specification before ordering to avoid costly field modifications or contact misalignment
- Ensure proper alignment during installation—even minor misalignment can reduce magnetic switch closure reliability and introduce audit trail gaps
- Plan wiring runs from contact to access control panel to avoid pinch points at frame edges and to maintain consistent electrical feedback
- Verify compatibility with your electromagnetic strike assembly mounting configuration before installation
The 5088-W is a straightforward, effective component for integrating magnetic door position feedback into access control systems. Specify it when frame constraints require low-profile hardware, when system design calls for reliable position monitoring integrated into controller logic, and when retrofit applications demand minimal structural modification.
