Reed Switch / Side Contact Sensor KONTAKTRON BOCZNY KN-06, MPN KN-06

KONTAKTRON BOCZNY KN-06 is a side-contact reed switch sensor designed to detect the presence of a magnetic field and to monitor the open or closed state of doors, windows, cabinets and similar fittings. The sensor is passive and provides a simple binary (on/off) output when a magnet moves into proximity of the side contact, making it suitable for integration with alarm panels, security systems and basic monitoring circuits where a compact side-mounted magnetic sensor is required.

Advantages

The side-contact design allows installation in narrow profiles or where surface-mounted sensors are unsuitable. As a passive reed switch, the KN-06 requires no internal power source and offers straightforward wiring for reliable open/closed detection. Its compact dimensions enable discreet placement and compatibility with a variety of frame and sash configurations. The sensor’s simple on/off behavior reduces integration complexity with conventional alarm inputs and low-voltage monitoring devices.

Suitable for

• Security systems and alarm panels for doors and windows
• DIY monitoring of cabinets, safes or small enclosures
• Gate and garage door position sensing in low-voltage systems
• Retrofit into narrow profiles or side-mounted locations

Key specifications

• Operating principle: side-contact reed switch (magnetic field detection)
• Output type: passive binary contact (on/off)
• Mounting style: side-mounted for narrow profiles or frames
• Application environment: low-voltage security and monitoring systems
• Typical use: door, window, cabinet and gate position detection

How to use

Install the sensor so its side contact faces the matching magnet mounted on the moving part (door, window or gate). Align the magnet and the side contact within the manufacturer’s recommended close proximity to ensure reliable switching. Connect the sensor in series with the alarm panel input or monitoring circuit using low-voltage wiring; as a passive device it does not require a power supply. Test operation by moving the magnet toward and away from the side contact to verify the circuit opens and closes as expected.

Usage recommendations

Place the sensor and magnet in protected locations to avoid mechanical damage and to maintain consistent alignment. Use appropriate weatherproof housings or sealing for outdoor or damp installations and adhere to low-voltage wiring practices—avoid running sensor wires alongside high-voltage or noisy signal cables to reduce interference.
