The main advantage of this model is the large operating gap of 20 mm. This allows for stable device operation even in the case of less precisely fitted window or door sashes, which often occurs in older buildings or with large gates. The solid housing made of high-quality white ABS plastic ensures not only mechanical durability but also an aesthetic appearance that discreetly blends into the window frame.
Installing the sensor is extremely simple and fast. The set includes dedicated mounting screws, and the design with a masking cover allows for the complete concealment of wiring and screws, which significantly increases the aesthetic value of the installation and hinders potential sabotage. The use of ruthenium (Ru) as a contact material guarantees exceptional service life and resistance to oxidation, which translates into years of trouble-free operation without false alarms.
By choosing this set, you receive three complete sensors, which is an economical and practical solution for securing a larger number of rooms. This is a professional choice for installers and individual users who care about the security of their property and want to create a solid perimeter protection system.

A set of three professional magnetic sensors (reed switches) designed for surface-mounted side installation. This is an ideal solution for those looking for a reliable way to secure entry points such as doors, windows, or garage gates. Thanks to their universal design, these sensors work perfectly with the most popular alarm systems on the market, including control panels from brands such as Satel, Bosch, Elmes, Ropam, or AVT.

Additional information
Operating principle: Why is the sensor electrically NO, but alarm-wise 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" (quiescent) 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 near), manufacturers call it NC.
From the point of view of pure electrical engineering, it is an NO circuit (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.
