The professional recessed magnetic sensor (reed switch) is a reliable solution dedicated to discreetly securing objects within alarm systems and smart home setups. Thanks to its unique design, this sensor is almost invisible after installation, making it an ideal choice for users who value interior aesthetics without compromising on the highest level of security. This model stands out for its support for two output states: NO (Normally Open) and NC (Normally Closed), which provides it with unrivaled versatility and allows it to work with any alarm control panel available on the market, such as Satel, Bosch, or Elmes.
A key advantage of the device is the increased operating gap of up to 30 mm. In practice, this means that the system will remain stable and free from false alarms even if the window or door leaf sags slightly over time or undergoes minimal deformation due to temperature changes. The solid housing made of durable ABS plastic is equipped with special centering teeth that guarantee a secure and permanent seating of the sensor in the mounting hole, eliminating the risk of it loosening during daily use.
The use of ruthenium (Ru) contacts is a guarantee of trouble-free operation for many years. Ruthenium is a metal with high resistance to burning and corrosion, which translates into millions of switching cycles without changing resistance parameters. The sensor outputs three wires: brown as common and two white for dedicated NO and NC outputs. This configuration allows the installer to flexibly choose the operating mode directly during connection to the system. The device is perfect for securing windows and doors made of both wood and plastic (PVC).

Additional information
Operating principle: What is the difference between NO and NC?
A reed switch is a switch controlled by a magnetic field. The "Normal" state always defines the behavior of the sensor at rest – that is, when the magnet is away.
NO type (Normally Open): * Without magnet: The circuit is broken (no current flow, resistance ∞ Ω).
With magnet: Bringing the magnet close to the sensor (e.g., closing a window) closes the circuit (resistance 0 Ω).
NC type (Normally Closed): * Without magnet: The circuit is closed (current flows, resistance 0 Ω).
With magnet: Bringing the magnet close to the sensor breaks the circuit (resistance ∞ Ω).
The sensor outputs 3 wires (brown – common, and two white for dedicated NO and NC outputs), which allows the installer to choose the desired mode during connection.
