## Long description

KONTAKTRON BRAMOWY KN-D2 — magnetic reed switch for door/gate monitoring is a wired door contact sensor intended to detect open and closed positions of doors and gates. The KN-D2 provides a sealed magnetic switching contact that integrates with alarm panels, access control systems and automation controllers to report the position of a moving element. The sensor is designed for basic intrusion detection and position monitoring where a simple, reliable magnetic contact is required.
Advantages
The KN-D2 uses a magnetic reed contact that offers low power requirement and mechanical simplicity, reducing points of failure. Its compact form factor allows discreet mounting on frames and gates while the sealed contact improves resistance to dust and moisture in typical indoor and sheltered outdoor installations. Being a wired sensor, it provides continuous signal transmission without the need for batteries and is compatible with common alarm and control inputs that accept normally open or normally closed contacts.
Suitable for
 Door monitoring in residential and commercial alarm systems
 Gate position detection for driveways or fenced entrances
 Access control monitoring for electric locks and interlocks
 Basic automation feedback to controllers and PLCs
Key specifications
 Type: magnetic reed switch (door contact)
 Mounting: surface-mountable compact sensor and magnet pair
 Connection: wired contact suitable for alarm and control inputs
 Contact function: magnetic normally open / normally closed switching (as configured by wiring)
 Environmental suitability: indoor and sheltered outdoor use (protected from direct weather exposure)
How to use
Install the sensor body on the door or gate frame and align the magnet on the moving leaf so that the two parts are adjacent when the door is closed. Connect the sensor wires to the corresponding input terminals of the alarm panel, access controller or automation device following the system wiring diagram and selecting the required contact polarity (NO/NC) if applicable. Test the installation by opening and closing the door to verify that the control panel or controller receives the change of state each time the magnet moves away from or toward the reed switch.
Usage recommendations
For reliable operation, mount the contact pair on flat, stable surfaces and keep the gap within the manufacturer's recommended distance. Route wiring through protected channels or conduit to avoid mechanical damage and interference. For outdoor gates, install the sensor in a sheltered location and inspect periodically for debris or alignment shifts that could affect switching.
