Key product advantages:
1. High reliability: The use of a contact made of ruthenium (Ru) ensures exceptional durability and resistance to oxidation, which translates into years of trouble-free operation even with frequent window opening.
2. Large operating gap: The 30 mm distance allows for stable sensor operation even in the event of slight shifts in window or door sashes resulting from building settlement or temperature changes.
3. Versatility: The reed switches work with most alarm control panels available on the market, including systems from brands such as Satel, Bosch, Elmes, Ropam, or AVT. Support for 2EOL/NC configuration facilitates professional installation.
4. Solid construction: The housing made of high-quality ABS plastic is characterized by high resistance to mechanical damage and a wide operating temperature range from -25°C to +85°C.
5. Complete set: By purchasing this product, you receive a set of 3 pieces, which allows for securing multiple entry points at an economical price.
These sensors are an indispensable element of perimeter protection, informing the alarm system of any attempt to open a secured window or door. Their round shape and white colour make them blend perfectly with modern joinery, ensuring safety without interfering with the room's design.

A set of three professional magnetic sensors (reed switches) designed for discreet recessed mounting. This is an ideal solution for those who value aesthetics and the highest level of security in alarm systems. Thanks to installation inside the window or door frame, the sensors remain almost invisible, which not only affects the interior appearance but also makes tampering by unauthorized persons more difficult.

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" (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 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 when the window is closed.
