Product information

Description

KONTAKTRON BOCZNY KN-04-BR is a side-mounted magnetic reed switch designed for detecting the presence or absence of a magnetic field. The compact side-mounted housing allows the device to be installed in narrow frames and profiles. The sensor operates as a simple contact element that closes or opens an electrical circuit when a magnet approaches or moves away, making it suitable for basic security and position-sensing applications.

Advantages

The side-mounted design enables discrete installation in doors, windows, and small enclosures where space is limited. The reed switch provides a passive, low-power switching solution that does not require onboard power to change state. Its simple mechanical-electrical operation ensures compatibility with standard alarm panels, access control systems, and other control circuits without complex configuration.

Suitable for

  • Door and window contact sensors in alarm and access control systems
  • Position sensing on sliding or hinged profiles
  • Basic open/closed state detection in cabinets and small enclosures
  • Retrofit installations where a side-mounted sensor is required

Key specifications

  • Mounting: side-mounted housing suitable for narrow frames and profiles
  • Switch type: magnetic reed switch (normally open / normally closed behavior depends on wiring and magnet orientation)
  • Operation: mechanical contact closure/opening in response to magnetic field proximity
  • Power: passive switching element—no internal power source required for sensing action
  • Compatibility: designed for use with standard alarm panels, access controllers and low-voltage circuits

How to use

Install the sensor in a side-mounted position aligned with the matching magnet so the required activation distance is achieved when the door or window is closed. Secure the housing to the frame using screws or adhesive as appropriate for the installation surface. Connect the switch leads to the control panel or circuit according to the required normally open or normally closed configuration. Test the operation by moving the magnet into and out of proximity to verify reliable switching and adjust positioning if necessary.

Usage recommendations

Place the sensor where the magnet will approach parallel to the reed element for reliable operation, and avoid mounting locations with strong external magnetic interference. Use suitable sealing or protection if the device will be exposed to moisture or dust, and ensure wiring connections are secured and insulated to prevent short circuits.
