## Summary description

KONTAKTRON CYLINDRYCZNY KN-02C is a cylindrical magnetic contact (reed switch) for security and sensing applications. Supplied under brand No name with model KN-02C (EAN 5902887034718), it provides a compact magnetic detection element intended for door/window monitoring, alarm systems, and basic position sensing. Designed for integration into electrical circuits to close or open contacts in presence of a magnetic field.

## Long description

KONTAKTRON CYLINDRYCZNY KN-02C is a cylindrical magnetic contact (reed switch) designed for simple magnetic detection tasks in security and sensing systems. The contact closes or opens an electrical circuit in response to a magnetic field, making it suitable for monitoring the state of doors, windows, or movable parts where detecting proximity or position change is required. Its compact cylindrical form allows discreet mounting in frames, casings or housings where space is limited.
Advantages
The KN-02C offers reliable operation based on proven reed-switch technology, ensuring consistent contact switching when exposed to a magnet. Its small cylindrical shape facilitates concealed installation and straightforward wiring into existing alarm or sensing circuits. The device has low power requirements and passive operation, which makes it compatible with a wide range of security control panels and simple position sensing applications.
Suitable for
Door and window contact in alarm systems
Basic position sensing for small moving parts
Integration into low-voltage detection circuits
Retrofit installations where compact sensors are required
Key specifications
Form factor: cylindrical magnetic contact
Operating principle: reed switch activated by external magnetic field
Mounting: designed for flush or concealed installation in frames or housings
Electrical interface: two-wire contact for series connection into detection loops
Power: passive device, requires no internal power source
Typical applications: door/window monitoring and basic proximity detection
How to use
Install the cylindrical body of the KN-02C in the fixed part of the structure (frame or housing) and align the actuator magnet or magnetised counterpart on the moving part (door, window or panel) so that the magnet approaches the contact when the part is closed. Connect the two wires of the contact in series with the alarm input or detection circuit according to the control panel manufacturer’s wiring scheme. Test operation by moving the magnet into the detection range to confirm the circuit opens or closes as expected and adjust alignment or mounting depth to ensure reliable switching.
Usage recommendations
Place the contact and magnet at the recommended mounting distance and ensure the magnet polarity and orientation produce consistent actuation. Avoid mounting near strong electromagnetic interference sources and protect the contact from moisture and mechanical damage for long-term reliability.
