binder addresses miniaturization in power supply systems
As modern machinery continues to shrink in size, the demand grows for powerful yet compact connectors. binder meets this need with its M12 Power connectors, which transmit high voltages reliably in space-critical environments. Due to changing application requirements, these connectors are increasingly replacing traditional 7/8″ connectors. However, the latter continue to play a crucial role—especially in legacy systems.
M12 connectors have become a standard for signal, data, and power transmission. Their compact design allows them to fit into tight spaces while still supporting voltages of up to 630 V. Since M12 connectors are widely recognised as a standard, they are easy to assemble in the field and integrate into machines.
Thanks to standardised codings—such as S, T, K, and L—these connectors offer not only safe but also precise solutions for a wide range of applications. For instance, S and K codings are typically used in AC applications, while T and L codings are optimised for DC power. This differentiated coding ensures high safety and flexibility across various system types.
While M12 solutions are increasingly used in modern, space-critical machines, 7/8″ connectors remain essential in existing systems. These connectors were specifically developed for high-voltage and high-power transmission and are known for their robust construction—making them ideal for applications where larger components are appropriate.
M12 Power connectors are compact and powerful, while 7/8″ connectors deliver proven reliability in existing systems. This allows automation professionals to respond flexibly to the needs of both modern and legacy infrastructure.
The product portfolios include solutions with 3 to 5 pins (depending on coding), comply with protection class IP67 or IP68 and meet UL standards (UL2237 & UL2238). They have a mechanical service life of more than 100 mating cycles and are suitable for operating temperatures from -40 °C to +85 °C.
To better integrate modern and legacy technologies, binder has developed an expanded range of accessories and practical interconnection solutions. These address both the trend toward more compact M12 Power connectors and the continued relevance of 7/8″ components.
New to the portfolio is a redesigned 7/8″ T-splitter available in three versions — 3-, 4-, and 5-pin. It was specifically designed for building high-performance networks in existing systems and offers simplified installation thanks to integrated mounting holes. This new version replaces the previous model.
Also new is a 5-pin T-splitter with L-coding, designed to meet the requirements of modern DC applications in the M12 format. Its compact design makes it particularly suitable for efficient and structured power distribution in space-constrained environments.
Another highlight includes two newly developed adapter solutions that enable intelligent connections between 7/8″ and L-coded connectors. These adapters support the gradual modernisation of existing systems and the flexible implementation of hybrid system architectures. All products are available immediately.
