## Summary description

Side-mounted magnetic reed switch (kontaktron) No name KN-CA52. Passive magnetic contact sensor designed to detect opening or closing of doors, windows or panels by a magnet in close proximity. Commonly used in alarm systems, access control and security monitoring as a compact side-mounted sensor for discreet installation.

## Long description

Side-mounted magnetic reed switch No name KN-CA52 is a passive kontaktron sensor designed to detect the presence or absence of a magnetic field when a door, window or panel is opened or closed. The compact side-mounted housing allows installation in narrow profiles and frames where surface-mounted contacts are not suitable. The sensor operates without internal power, changing its electrical state when a magnet approaches or moves away, making it compatible with common alarm systems and access control inputs that accept passive reed contacts.
Advantages
The side-mounted design enables discreet installation in door and window frames with limited depth while preserving reliable contact detection. The passive reed mechanism requires no internal power source, providing long-term stability and very low maintenance. The sensor’s compact dimensions and simple mounting make it adaptable to a variety of frames and panel types, and it offers consistent switching performance when paired with an appropriately positioned magnet.
Suitable for
 Security and alarm systems for doors and windows
 Access control installations with passive contact inputs
 Discrete monitoring of small panels, cabinets or sliding profiles
 Retrofit installations where minimal visible hardware is required
Key specifications
 Mounting type: side-mounted for narrow frames and profiles
 Operating principle: magnetic reed contact (passive, normally open/closed depending on wiring)
 Power: passive, no internal power required
 Typical applications: doors, windows, panels, cabinets
 Environmental use: intended for indoor installation in standard residential or commercial environments
 Connection: two-wire contact interface compatible with standard alarm and control panels
How to use
Install the kontaktron in the side recess or on the edge of the frame so that the mating magnet aligns precisely when the door or window is closed. Secure the sensor with screws or adhesive as appropriate for the frame material, and route the two contact wires to the alarm or access control input. Configure the connected control system to recognise the passive reed contact state and test operation by bringing the magnet close to the sensor and moving it away to confirm reliable switching. Ensure correct polarity and input type in the receiving device if required by the control panel.
Usage recommendations
Position the magnet within the manufacturer’s recommended gap for consistent detection and avoid mounting near strong external magnetic sources or large ferrous objects that can affect sensitivity. For outdoor or damp environments, use additional sealing or place the sensor within a protected profile to prevent moisture ingress. Verify compatibility with the alarm or access control input and perform periodic functional checks as part of routine maintenance.
