Magnetic contact sensor SATEL B-2 BR for doors and windows, surface-mounted, brown

The SATEL B-2 BR is a surface-mounted magnetic contact sensor for doors and windows, finished in brown to blend with wooden frames and interior fittings. The device uses a reed switch and a separate magnet element to detect opening and closing events, providing a simple and reliable input for alarm and access control systems. Designed for indoor installation, the sensor supports discreet monitoring where low-profile appearance and dependable contact detection are required.

Advantages

The sensor offers straightforward surface mounting and a compact form factor that minimizes visual impact on doors and window frames. Its reed-switch design ensures low power consumption and stable performance over long service life. The brown finish reduces visibility on wooden or dark-coloured surfaces, and the sensor is compatible with conventional wired alarm and control panels that accept magnetic contact inputs.

Suitable for

• Monitoring residential and office doors and windows
• Integration with alarm control panels and access control systems
• Applications where surface mounting is required or retrofitting is needed
• Indoor use in living spaces, corridors, and utility rooms

Key specifications

• Type: Magnetic contact (reed) sensor for doors and windows
• Mounting: Surface-mounted installation
• Finish: Brown colour suitable for wooden frames
• Operation: Detects opening and closing via magnet and reed switch interaction
• Installation environment: Indoor use
• Compatibility: Works with standard wired alarm and access control inputs

How to use

Position the main sensor body and the magnet element at the specified gap on the door or window and its frame, ensuring alignment so the magnet passes close to the reed switch when closed. Mount both parts on the surface using screws or adhesive as appropriate for the installation surface. Connect the sensor's terminals to the alarm or control panel input following the panel manufacturer's wiring diagram and observe polarity and tamper requirements if applicable. After wiring, test the contact by opening and closing the protected door or window to confirm reliable state changes at the control panel.

Usage recommendations

For reliable operation, install the sensor on clean, dry surfaces and avoid positions where the magnet and reed switch are obstructed or subject to impact. Maintain the recommended gap specified by the system installer to ensure consistent detection. Use the brown finish to match dark or wooden frames for a less obtrusive appearance, and verify compatibility with the alarm panel's input type before installation.
