## Summary description

KONTAKTRON BOCZNY KN-02 is a side-mounted magnetic reed switch (contact sensor) from No name. It provides a simple magnetic contact for door or window monitoring and basic security or automation circuits. The unit is intended for detecting open/closed states via a magnet actuator and can be used in alarm systems, access control, or DIY electronic projects.

## Long description

KONTAKTRON BOCZNY KN-02 is a side-mounted magnetic reed switch designed to detect open and closed states of doors, windows or other movable elements. The compact contact sensor operates with a separate magnet actuator and provides a normally open or normally closed contact change when the magnet approaches or moves away. Intended for simple monitoring tasks, the unit suits basic alarm systems, access control inputs and low-voltage automation circuits or hobby electronics where a reliable magnetic switch is required.
Advantages
The side-mounted design allows installation in narrow frames and constrained spaces while maintaining a secure magnetic actuation. The reed switch is passive and requires no internal power, which simplifies wiring and integration into alarm panels or microcontroller projects. Its straightforward mechanical and magnetic operation results in reliable state detection with low maintenance needs.
Suitable for
Door and window open/close monitoring in alarm systems
Access control inputs and interlocks
Home automation sensors and presence detection
DIY and electronics prototyping with microcontrollers
Key specifications
Mounting style: side-mounted magnetic reed switch
Actuation method: magnet-operated contact
Contact type: mechanical reed contact (change on magnet proximity)
Operating environment: indoor use for door/window frames and similar applications
Electrical characteristics: suitable for low-voltage DC circuits and alarm inputs (observe panel input ratings)
Physical form factor: compact sensor body designed for narrow profiles
How to use
Install the sensor body on the fixed frame and align the magnet actuator on the moving part so that the magnet passes close to the contact when the element is closed. Secure mounting with screws or appropriate adhesive depending on the installation surface. Connect the reed switch leads to the alarm panel, controller input or circuit according to the required normally open or normally closed configuration and follow the input device wiring recommendations. Test the switching action by moving the magnet to confirm consistent detection and adjust alignment if necessary.
Usage recommendations
Position the sensor and magnet with minimal gap for reliable operation; avoid placing strong external magnetic sources nearby. Use within the voltage and current limits of the connected alarm panel or controller to prevent contact wear. For outdoor or high-humidity applications, provide additional protection or choose a sealed variant.
