Lumberg has expanded its Series 45 high-current connector portfolio with new matching tab contacts, giving engineers more options for compact, high-power connections in electronic systems. The additions include types 459000, 459010, 459020 and 459120, designed to work with the company’s existing socket contacts. The expansion is particularly relevant for designers of power electronics, industrial equipment and automotive systems, where high current capacity, limited PCB space and simplified assembly are key requirements. By offering both sides of the connection, Lumberg also aims to make component selection and sourcing easier for engineering and purchasing teams. High-current connections up to 200 A Lumberg’s Series 45 socket contacts can handle currents of up to 200 A, depending on the contact version, PCB connection and thermal conditions. The contacts combine low contact resistance with optimized geometries to reduce electrical losses and self-heating. Their compact footprint makes them suitable for electronic assemblies with high power density, where available board space and thermal management can present significant design challenges. The Series 45 range also supports pluggable connections between stacked PCBs, providing an alternative to conventional wiring and additional intermediate connectors. In this configuration, a socket contact is mounted on one PCB using surface-mount technology (SMT) or through-hole technology (THT), while a matching tab contact is installed on the opposing assembly. Depending on the socket design, the tab can be inserted from above, below or the side. This gives engineers greater freedom when developing modular systems with vertical or horizontal power distribution. New tab contacts simplify PCB integration The latest additions introduce matching 0.8 mm THT tab contacts to Lumberg’s own product lineup, allowing customers to source both socket and mating contacts from a single supplier. The expanded offering includes six versions in two widths, 4.6 mm and 6.3 mm, with overall lengths ranging from 12.6 mm to 18 mm. An angled 20 mm version is also available for applications requiring a different connection orientation. These mechanical options allow designers to adapt the contacts to different board layouts, installation spaces and assembly configurations without relying on separately sourced mating components. Targeting power electronics and automotive applications The expanded Series 45 portfolio addresses the growing need for compact, reliable power connections in industrial electronics, automotive engineering and other high-current applications. For manufacturers working with stacked PCBs or modular power assemblies, the coordinated socket and tab contact range could help reduce wiring complexity and simplify assembly processes. Having matching components available from one supplier may also streamline procurement and reduce the effort involved in selecting compatible contacts for new designs.
