2Pair Wired Rolling Magnetic Contact Gate Switch Alarm Security with Adhesive Tape Product overview A set of two wired magnetic contact sensors designed for gate and door security. Each pair includes a magnetic sensor and a rolling contact actuator for reliable detection of open and closed states. Adhesive tape is supplied for quick surface mounting. Key benefits Reliable detection: Wired connection provides continuous monitoring for alarm panels, access controllers, or automation inputs. Consistent contact on moving surfaces: Rolling magnetic contact design adapts to sliding or uneven movement, reducing missed signals. Easy installation: Adhesive tape enables fast, temporary or permanent mounting without special tools. Wired hookup supports long term, secure connections. Versatile use: Compact sensors fit most gates, doors, and shutters where a magnetic contact switch is required. What this product does Detects open and closed status of gates, doors, or shutters and sends a signal to a connected alarm or control system. Works as a basic switch for security alarms, gate control logic, or monitoring circuits. Compatibility and fitting Wired interface makes these sensors compatible with most alarm panels, access control units, gate controllers, and home automation inputs that accept magnetic contact switches. Compact size and low profile suit installation on sliding gates, swing gates, garage doors, roller shutters, and similar applications. Adhesive tape included for surface mounting; wired connections allow integration into permanent installations. Materials and performance Electronic magnetic contact design provides stable operation for on off detection.
