Magnetic Reed Switch (Side) No name KONTAKTRON BOCZNY KN-M02

KONTAKTRON BOCZNY KN-M02 is a side-mounted magnetic reed switch designed for detecting the presence of a magnetic field and the open/closed status of doors or windows. The sensor is a passive, normally-open reed contact enclosed in a compact side housing that allows discreet installation along frames and narrow surfaces. It connects with two wires and is compatible with standard magnetic contact circuits and low-voltage control panels used in alarm and security systems.

Advantages

The side-mounted design enables installation in confined spaces and along the edge of frames where surface contacts may not fit. As a passive normally-open reed switch, it requires no internal power and provides a simple, reliable binary signal when a magnet is present. The compact housing reduces visual impact and simplifies mounting with basic wiring. Compatibility with standard alarm and security circuits allows easy integration into existing systems.

Suitable for

• Door and window open/closed status monitoring in residential and commercial alarm systems
• Security contacts for cabinets, access panels and small enclosures
• Simple position sensing in low-voltage control circuits and DIY security projects

Key specifications

• Mounting type: side-mounted housing for frame-edge installation
• Contact type: passive normally-open (NO) reed switch
• Connection: two-wire lead for integration with standard alarm circuits
• Housing: compact profile suitable for narrow mounting spaces
• Operating environment: intended for low-voltage indoor security and control applications

How to use

Install the reed switch on the frame or edge of the door/window so the magnet mounted on the moving part aligns with the switch when closed. Run the two-wire connection to the alarm control panel or monitoring device and wire it into the appropriate input configured for a normally-open contact. Verify correct alignment and test the circuit by moving the door or window to confirm the contact closes when the magnet is nearby and opens when separated. Ensure wiring and mounting follow the control panel manufacturer’s instructions and local safety standards.

Usage recommendations

For reliable operation, mount the sensor and magnet on stable surfaces and avoid placing them near strong external magnetic fields or ferrous objects that could affect switching distance. Use suitable gauge wiring and secure connections; check compatibility with the control panel’s input type and any required tamper or supervision circuitry when adding to alarm systems.
