Finder Products for the Railway Sector

With over 70 years of expertise in the design and manufacture of electronic and electromechanical components, Finder offers a comprehensive range of dedicated and certified devices specifically designed to meet the demands of railway infrastructure.

Every component installed in the railway sector must feature precise characteristics and resist extreme environmental and mechanical stresses.

Finder catalog products designed for this sector are identified by the final letter “T” in the product code. They are characterized by wider operating ranges, an extended temperature and humidity range, and excellent tolerance to mechanical shock.

They comply with the requirements of the main international railway standards, such as:

- EN 45545: for fire protection and maximum fire resistance of plastic materials.
- EN 50155: for the operating range under specific temperatures and environmental conditions.
- EN 61373: for high resistance to shock and vibration.

The catalog includes various types of devices designed for multiple applications:

- Relay interface modules (39T Series) and Relays with forcibly guided contacts (7S Series): These are essential to ensure maximum functional safety in railway signaling, door control, and door opening/closing systems.

- Relays for railway applications (46T, 55T, and 56T Series): The 46T Series (8 A or 16 A miniature power relays) safely manages control consoles, pantographs, doors, and variable message panels. The 55T Series (7 A, 4 CO industrial relays) and the 56T Series (12 A power relays) control air conditioning systems, external and internal lights, pantographs, and bogie status.

- Timers and Timer modules (80T, 83T, and 86T Series): The 80T Series (modular timers) and the 86T Series (plug-in timer modules) coordinate door opening and on-board appliances. The 83T Series is also used for timing workshop sockets and control consoles.

- Voltage and light control (70T and 11T Series): The 70T Series voltage monitoring relays operate with positive safety logic to monitor phase loss and phase sequence in three-phase networks (ideal for air conditioning and workshop sockets). The 11T Series light dependent relays optimize the management of external lights and control consoles based on ambient light.

On board trains, such as inside passenger or restaurant cars, Finder integrates solutions designed for device power supply and load management:

- 25 A Modular contactors (22T Series): Used to safely enable power sockets for PCs or smartphones and for the optimized management of on-board appliances in restaurant cars.

- Sockets and power supplies from the 4box range: For seamless integration between passenger seats, compact solutions are employed, such as the P40 2-module electrical socket, the 20W flush-mounting USB charger (USB CA 20W), and the SIDE PANNELLO 2-module electrical socket, ensuring a constant and safe power supply throughout the journey.
