The use of high-class ruthenium (Ru) contacts guarantees exceptional durability, stability of electrical parameters, and a long service life, even with frequent opening and closing of the secured points. The sensor operates in an NC (Normally Closed) configuration, making it fully compatible with most alarm control panels available on the market. The device is resistant to a wide temperature range, from -25°C to +85°C, which confirms its versatility and readiness for operation in variable weather conditions. Surface mounting is quick and intuitive, allowing for rapid securing of the facility without the need to interfere with the structure of the door frames.
This solution combines aesthetics, durability, and precision of operation. By choosing this model, you are investing in the security of your property, using technology proven in professional alarm installations. Each element of the set has been designed to ensure maximum tightness and protection against external factors, which makes it one of the most frequently chosen sensors by security system installers.

Professional side magnetic sensor (reed switch) enclosed in a durable aluminium housing, designed for alarm systems requiring the highest reliability. Thanks to a large operating gap of 35 mm and a hermetic design, this sensor is an ideal solution for securing garage doors, entrance gates, and heavy door/window frames in industrial and residential facilities. The solid aluminium construction provides excellent resistance to corrosion and mechanical damage, allowing for trouble-free operation in harsh outdoor conditions.

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 that?
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 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.
