Magnetic Reed Switch Sensor SATEL K-2 2E BR recessed 2EOL/NC brown

The SATEL K-2 2E BR recessed magnetic reed switch sensor is a compact, brown-housed device intended for discreet installation on doors and windows. It features a recessed design that allows the sensor and magnet to be embedded into frame or sash profiles, making it suitable for installations where aesthetics and concealment are important. The sensor provides two separate end-of-line normally closed contacts for connection to alarm systems and access control panels, enabling supervised detection of perimeter openings.

Advantages

The recessed form factor reduces visible hardware and maintains the appearance of wooden frames and profiles. Having two EOL/NC contacts supports supervised circuit topologies and allows flexible wiring options for monitoring multiple points or redundancy. The brown housing matches wood-coloured frames to minimize visual contrast, and the magnetic reed design ensures reliable operation with low maintenance requirements.

Suitable for

• Concealed installation in wooden door and window frames
• Perimeter intrusion detection for residential and commercial premises
• Integration with alarm control panels and access control systems
• Supervised circuits requiring end-of-line monitoring

Key specifications

• Recessed magnetic reed switch format for embedded mounting
• Two normally closed contacts with end-of-line supervision
• Colour: brown, suitable for wood and dark profiles
• Compact housing designed for frame and sash profiles
• Intended for door and window contact detection

How to use

Install the sensor and magnet into matching recesses in the door or window frame and sash so that the magnet aligns with the reed switch when the opening is closed. Connect the two normally closed contacts to the alarm panel or access controller following the supervised circuit wiring scheme required by the control equipment. Verify correct alignment and operation by closing and opening the door or window and observing the panel’s input status. Secure the housing in place with appropriate fasteners and cover caps where applicable to maintain the recessed appearance.

Usage recommendations

Use in conjunction with compatible alarm panels that support end-of-line supervision and consult the control panel documentation for recommended resistor values and wiring diagrams. For best results, drill precise recesses to ensure proper alignment of sensor and magnet and avoid placing the sensor near sources of strong magnetic interference.
