The main advantage of the model is its versatility and well-thought-out design. Equipped with a mounting cover, it allows for complete concealment of the wiring, which not only improves the aesthetics of the installation but also hinders potential sabotage. Special notches in the housing allow for flexible cable routing from the side or front, which significantly facilitates installation in hard-to-reach places.
The sensors are characterised by a large operating gap of up to 25 mm, which guarantees stable operation even in the case of loosely fitted door or window leaves. The use of ruthenium (Ru) as a contact material ensures exceptional durability and reliability for years, eliminating the problem of contact sticking. The set is fully compatible with most alarm control panels available on the market, including systems from brands such as Satel, Bosch, Elmes, Ropam, or AVT. It is a 2EOL/NC type solution with built-in parametric resistance of 2 x 1.1k Ohm, which simplifies installation in advanced systems requiring line parameterisation. By choosing this set, you receive a complete solution for securing three entry points, combining professional build quality with ease of installation.

A set of three professional magnetic sensors (reed switches) in brown, designed for discreet and effective property protection. These surface-mounted side sensors are an ideal solution for protecting windows, doors, and other moving elements in alarm systems. Thanks to the brown housing made of high-quality ABS plastic, the sensors blend perfectly with dark window and door joinery, remaining almost invisible to unauthorised persons.

Additional information
Operating principle: Why is the sensor electrical NO and alarm NC?
The operation of the sensor is very simple: bringing the magnet closer (closing the window) closes the circuit, and moving the magnet away (opening the window) breaks the circuit.In the alarm industry, this sensor is sold as NC (Normally Closed). Why is this?
In alarm systems, the 'normal' (resting) state is a secured building – i.e., a closed window.
Since the circuit is closed and current flows when the window is closed (magnet is close), manufacturers call it NC.
From the point of view of pure electrical engineering, it is an NO system (because by default, lying on a table without a magnet, the sensor does not conduct current), however, alarm installers always look at the operating state with the window closed.
