## Summary description

Side-mount magnetic reed switch KONTAKTRON BOCZNY KN-M04 (No name, MPN KN-M04). A mechanical magnetic contact sensor for detecting door or window position using a magnet and reed contact. Designed for mounting on the edge or side of frames, suitable for alarm systems, access control, and simple open/close state monitoring in residential or commercial installations.

## Long description

Side-mount magnetic reed switch KONTAKTRON BOCZNY KN-M04 is a mechanical magnetic contact sensor designed to detect the open or closed position of doors and windows. The sensor consists of a reed contact enclosed in a housing that changes state when a magnetic field from a separate magnet is present. Its side-mount design allows installation on the edge of frames where surface mounting is impractical or where a discreet contact point is required. The device is suitable for integration with alarm systems, access control panels, and basic status monitoring circuits in residential and commercial buildings.
Advantages
The side-mount form factor enables installation on narrow frame edges and profiles, providing a compact and unobtrusive sensing point. The reed contact mechanism is passive and requires no internal power to detect a magnet, which makes it reliable and energy-efficient when used with external control equipment. The simple mechanical construction offers long-term durability when used within its rated environment and allows straightforward wiring and replacement.
Suitable for
Monitoring door and window open/closed status in alarm systems
Basic access control and entry detection
State feedback for automation or building management systems
Low-voltage security and monitoring circuits in residential or commercial installations
Key specifications
Mounting style: side/edge mounting suitable for frame profiles
Contact type: magnetic reed contact (normally closed or normally open depending on wiring and magnet position)
Operating principle: magnet-actuated mechanical switching
Suitable environment: indoor installation, standard residential and commercial conditions
Connection: simple two-conductor wiring for integration with security panels or monitoring circuits
How to use
Install the reed switch on the frame edge where the magnet will align with the contact when the door or window is in the closed position. Secure the sensor using screws or adhesive appropriate for the surface, ensuring correct alignment and gap tolerance between sensor and magnet. Connect the two conductors to the alarm panel or control input according to the system wiring requirements, observing polarity if specified by the controller. Test the installation by opening and closing the door or window and verifying that the control system registers the change in state.
Usage recommendations
Place the magnet as close as the manufacturer’s recommended gap allows to ensure reliable switching; avoid mounting near strong external magnetic fields or metal obstructions that may affect operation. Use appropriate low-voltage wiring and follow local electrical codes when integrating the switch into alarm or access control systems. For outdoor or high-humidity environments, select an enclosure or location that protects the device from direct exposure to weather.
