We Design. We Build. We Deliver.
Precision-engineered switching solutions available with local technical consultation across Barcelona and the broader Iberian peninsula.
The industrial landscape of Barcelona and the surrounding Catalonia region represents one of Southern Europe’s most sophisticated technology hubs. From the innovation districts of 22@ Barcelona to the high-capacity manufacturing plants along the Zona Franca logistics corridor and Martorell’s automotive center, original equipment manufacturers (OEMs) demand high-reliability electromechanical components. As energy density increases and PCB real estate shrinks, selecting the correct Printed Circuit Board (PCB) Relay is no longer merely a basic hardware choice—it is a cornerstone of system thermal management, arc suppression efficiency, and electromagnetic compatibility (EMC).
Altran Magnetics, together with its strategic power component engineering frameworks, designs and manufactures high-performance PCB relays, signal relays, power relays, and epoxy-sealed DC contactors engineered specifically to solve complex switching challenges. Whether your engineering team is specifying subminiature signal switching for IoT controllers or heavy-duty 40A miniature power relays for EV charging stations (EVSE), understanding the nuances of contact resistance, coil dissipation, dielectric strength, and creepage distance under European Low Voltage Directives (LVD) is critical.
Information Gain Insight: Modern PCB power relays specified for the Iberian market must withstand continuous thermal stress in high ambient temperature enclosures while maintaining low contact resistance (<30 mΩ). Altran Magnetics utilizes advanced Silver Tin Oxide (AgSnO2) contact matrices to prevent material transfer and contact welding under severe capacitive and inductive inrush loads.
When designing power switching circuits for European market deployment, engineers in Barcelona must adhere strictly to IEC/EN 61810-1 standards. Our PCB relay lines integrate several proprietary structural innovations to maximize endurance and reduce total cost of ownership:
Featuring specialized AgSnO2 and AgNi contact materials, engineered to extinguish micro-arcs during AC/DC break cycles. This significantly reduces contact erosion and extends mechanical life up to 10,000,000 operations.
Designed with reinforced insulation barriers offering up to 5,000 VAC dielectric strength between coil and contact circuits, meeting impulse voltage requirements according to IEC 60664-1 overvoltage Category III.
Bistable (latching) and sensitive DC coil configurations reduce standby power consumption down to 200 mW, aiding local Barcelona manufacturers in meeting stringent EU Eco-Design directives.
Barcelona is not only a cultural beacon but also a primary industrial driver within Catalonia, accounting for a massive share of Spain’s export-driven electronics, automotive, and green-energy manufacturing. Our PCB relays and magnetic switching components are actively specified across five critical local industry verticals:
With major automotive production centers in Martorell and the surge in urban charging points across the Barcelona Metropolitan Area (AMB), our 30A-50A PCB power relays serve as main disconnect relays inside Level 2 AC wallboxes and auxiliary pilot switches in DC fast chargers.
Catalonia's aggressive solar energy rollout and industrial microgrid installations in Vallès Occidental require reliable isolation. Our high-voltage DC contactors and latching PCB relays manage battery disconnects and grid tie switching with minimal parasitic drain.
In the automated assembly lines of Zona Franca and local OEM control panel builders, our PCB relays actuate solenoid valves, drive safety interlocks, and interface programmable logic controllers (PLCs) with high noise immunity.
Barcelona's hotel, retail, and commercial building sectors rely on modern Building Energy Management Systems (BEMS). Our definite purpose contactors and miniature PCB relays deliver whisper-quiet operation and zero maintenance for fan coil units and heat pumps.
Supported by the Catalonia Health Innovation Ecosystem, medical device developers utilize our hermetically sealed signal relays to ensure zero contact oxidation during micro-amp signal switching in clinical diagnostics equipment.
Our dedicated European engineering team provides custom terminal layout design, specific pin-spacing matching for drop-in replacements, and specialized coil voltage tuning (e.g., 12VDC, 24VDC, 110VAC, 230VAC) directly to local procurement teams.
To maintain market leadership, purchasing managers and R&D engineers in Catalonia must keep pace with rapid technological shifts. Semantic search analysis reveals key trending topics driving component sourcing decisions in North-Eastern Spain:
Driven by next-generation EV platforms and ultra-fast DC charging hubs, standard 400V switching is giving way to 800V and 1000V DC ratings. Designers require gas-filled arc chambers to safely interrupt high-DC voltages without sustained plasma arcing.
As power electronics migrate to Silicon Carbide (SiC) and Gallium Nitride (GaN) power stages, passive components and electromechanical relays must shrink. Narrow-profile PCB power relays (width < 15mm) are seeing skyrocketing adoption in compact inverter topologies.
Iberian OEMs are actively mitigating supply chain bottlenecks by partnering with suppliers offering dual-source capability, full REACH chemical compliance, and transparent conflict mineral declarations (CMRT).
Evaluating the right switching technology requires balancing footprint, continuous load capacity, peak surge tolerance, and thermal performance. The technical table below outlines the core attributes across our standard product classifications:
