One of the areas in which ELTRON has been providing proven and reliable solutions for years is human-machine interfaces (HMI). In this area, we offer products from the Eao brand, being a long-standing authorised official distributor of this manufacturer in Poland. The availability of Eao components at ELTRON is complemented by technical and advisory support at the stage of selection and implementation of solutions in specific industrial applications.

Long-term cooperation between ELTRON and Eao

EAO is a renowned manufacturer of control and signalling components, known for its high quality, ergonomics and resistance to harsh environmental conditions. The brand's solutions are used in machine automation, industry, critical infrastructure and applications dedicated to railway transport.

At ELTRON, we have been supporting our customers for years in the selection and implementation of EAO components - from individual control elements to complete panel solutions, designed for long-term and reliable operation.

A cross-section of the EAO range available at ELTRON

The EAO range available at ELTRON includes a wide range of HMI components designed for safe and intuitive operation of machines and technical systems. These include:

• control and signal buttons,
• switches and function selection elements,
• control lamps and LED indicators,
• complete operator units,
• special solutions for railway and industrial applications.

Eao products are characterised by high mechanical durability, resistance to vibrations and environmental factors, and compliance with standards used in industry and rail transport.

The most popular Eao solutions in the ELTRON range

Based on many years of cooperation with ELTRON customers and real project implementations, we can identify groups of Eao products that are most often chosen for industrial and railway applications. These are solutions that have been proven in operation, are repeatable in design and available in many functional configurations.

Pushbuttons and Control Elements Ø16, Ø22, and Ø30

One of the basic Eao product groups offered by ELTRON are control buttons and panel switches in standard mounting diameters of Ø16 Ø22 and Ø30. These components are used in operator consoles, control cabinets and machine panels, where ergonomics, legibility and mechanical durability are of key importance.

ELTRON's offer includes, among others:

• monostable and bistable buttons,
• rotary and key switches,
• emergency STOP buttons,
• signalling elements with LED backlighting.

These solutions are commonly used in industrial machines, production lines and infrastructure control systems, including in environments with increased operational requirements.

Modular control systems and operator units

Eao offers modular control element systems that enable flexible design of operator panels for specific application requirements. The modular design allows control, signalling and safety functions to be combined in a single, consistent user interface.

These solutions are used, among others, in:

• operator stations,
• machine and production line consoles,
• process control systems,
• OEM applications requiring repeatable configurations.

ELTRON supports customers in selecting the right components, configuring sets and adapting Eao solutions to design and regulatory requirements.

Control and signaling components for railway applications

A special category within the EAO product line available at ELTRON consists of components dedicated to railway applications, where technical requirements significantly exceed those of standard industrial applications.

These products are designed with the following in mind:

• resistance to prolonged vibrations and mechanical shocks, in accordance with the European standard EN 61373,
• stable operation over a wide temperature range,
• high reliability in continuous operation, in accordance with the requirements of EN 50155,
• meeting the requirements for components used in rail transport, including the Technical Specifications for Interoperability (TSI) and UIC 612 specifications,
• ensuring fire safety through the use of V-0-rated materials compliant with the requirements of EN 45545-2

EAO components are used in train driver’s cabs, control panels, auxiliary systems for rail vehicles, and railway infrastructure. ELTRON has experience in supplying these solutions for railway projects and special applications.
