Magnetic door/window open sensor bleBox openSensor black 2m — wireless contact sensor with 2 m cable

bleBox openSensor black 2m is a magnetic door and window contact sensor with a 2-meter wired connection for flexible installation. The device detects opening and closing events through a magnetic contact and is designed for integration into bleBox smart home systems and compatible automation platforms. The sensor provides reliable status monitoring of doors or windows and can trigger events or notifications in connected smart home controllers.

Advantages

The openSensor offers a compact, low-profile design in black that is suitable for discreet mounting on frames and sashes. Its 2 m cable enables flexible placement of the sensor body and magnet, allowing installation where space or alignment is limited. The wired magnetic contact provides direct, immediate state detection without relying on radio for the contact itself, which simplifies integration with wired-capable controllers and reduces latency for state changes.

Suitable for

• Monitoring doors and windows in residential or commercial premises
• Triggering automation routines such as lighting, heating, or alarm systems
• Integrating with bleBox controllers and other smart home platforms that accept wired magnetic inputs
• Remote status notifications and event logging for access control

Key specifications

• Sensor type: magnetic reed/contact sensor for open/close detection
• Cable length: 2 meters for flexible mounting
• Colour: black for discreet installation
• Mounting: surface mount on door/window frame and sash
• Output: wired contact suitable for integration with smart home controllers

How to use

Mount the sensor body on the door or window frame and align the magnet on the moving sash so that they meet at the specified closed position. Use the 2 m cable to position the sensor where needed and connect the wires to the input terminals of a compatible bleBox controller or other automation controller supporting external magnetic contacts. After mechanical installation and electrical connection, verify correct operation by opening and closing the door or window and checking status updates in the controller or associated app.

Usage recommendations

Place the sensor components so that the magnet and contact align precisely when the door or window is closed to ensure reliable detection. Avoid sharp bends or pinching of the cable during installation, and route wiring away from moving parts. Test the connection in the target controller to confirm correct polarity and signal recognition before finalising mounting.
