Made of high-quality, hard white ABS plastic, the sensor provides an aesthetic appearance and high resistance to mechanical damage. The well-thought-out design with a mounting cover allows for complete concealment of the wiring, which not only enhances the visual appeal of the installation but also effectively protects the cables against accidental damage or sabotage attempts. The heart of the device is a contact made of ruthenium (Ru), which guarantees reliability over thousands of operating cycles and exceptional resistance to contact oxidation.
The sensor operates in NC mode (Normally Closed when the magnet is near), which is the standard in the professional alarm industry. Thanks to universal electrical parameters, the product works seamlessly with alarm control panels from leading manufacturers such as Satel, Bosch, Elmes, Ropam, or AVT. Surface mounting is quick and simple thanks to the included mounting screws. A wide operating temperature range (from -25°C to +85°C) allows the sensor to be used in difficult environmental conditions, both inside buildings and in unheated technical rooms or garages. By choosing this model, you gain the certainty of stable alarm system operation and effective perimeter protection for your facility.

Professional side magnetic sensor (reed switch) designed for advanced security and automation systems. The device is characterised by an exceptionally large operating gap of up to 50 mm, making it an ideal solution for securing garage doors, entrance gates, and large door or window leaves where standard sensors may fail due to natural structural clearances or large distances between elements.

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 (the magnet is near), 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 when the window is closed.
