Key Features
- Heavy-duty reliability: cast aluminum housing and hermetically sealed reed switch protect sensors in harsh, outdoor or industrial environments.
- Flexible installation: low-profile floor-mount design and universal magnet mounting handle tight or angled overhead door applications for faster installs.
- Tamper- and weather-resistant: two-foot stainless steel armored cable shields wiring from damage and tampering for continuous security monitoring.
- Wide sensing range: standard gap up to 2.5" (up to 3" in some installs) reduces alignment hassles and ensures consistent open/closed status.
- Fail-safe contact and compatibility: SPDT (Form C) contact with options for EOL resistors/diodes simplifies integration with alarm panels and surveillance systems.
- Lifetime limited warranty: long-term protection that reduces maintenance costs and downtime for critical access control points.

Overview
Optimize perimeter security and overhead door monitoring with the George Risk Industries 4532C miniature overhead door switch. This magnetic contact is built for demanding security and surveillance installations—its cast aluminum case and hermetically sealed reed switch deliver durable, weatherproof performance where reliability matters most. The floor-mount, low-profile design and universal magnet mounting make alignment easier, and the standard 2.5" gap (wide-gap capability up to 3") reduces sensitivity to misalignment on large or angled doors. With a robust two-foot stainless steel armored cable and SPDT (Form C) contacts rated for DC operation, the 4532C integrates cleanly with alarm panels, access control, and monitoring systems. Optional EOL resistors and diodes further streamline wiring for tamper detection and alarm supervision. Ideal for commercial dock doors, overhead bay doors, and other high-traffic access points, the 4532C helps prevent false alarms while maintaining dependable status reporting. Upgrade your facility’s door sensing with this rugged George Risk magnetic contact—contact us to order or specify for your next security project.
