According to Binder, M12 connectors are an integral part of modern automation systems. This is because they are needed wherever signals, data and power need to be transmitted reliably. At the same time, the requirements for safe and consistently high-quality assembly in the field are increasing. The company has therefore responded by adapting the design so that the threaded rings of the overmolded and shielded M12 connectors will in future be designed with a combination of knurl and hexagon. In contrast to the previous design, the new geometry also enables assembly with a tool for the first time—for example with a torque wrench. As a result, users benefit from greater process reliability and consistently high assembly quality, which is particularly beneficial in cases where a controlled screw connection is crucial. Typical areas of application include automation technology, mechanical and plant engineering and wherever these connectors have to be installed under defined mechanical conditions. Especially in applications with increased requirements for vibration resistance and long-term stability, the controlled screw connection ensures the necessary safety.

Users Benefit from the new binder portfolio

According to Binder, the adaptation follows clear requirements from the market! This is because in many industrial applications, standard-compliant and traceable assembly is increasingly required. By integrating the hexagon, the connectors can now be tightened in a controlled manner and thus meet common industrial specifications. At the same time, Neckarsulm is also ensuring greater consistency in its portfolio. While the combination of knurl and hexagon is already established for unshielded variants, this design is now also being transferred to shielded M12 connectors. This results in a uniform design across different variants—an advantage for design, assembly and maintenance, says the manufacturer. The combination of knurl and hexagon enables both quick manual pre-assembly and precise retightening. This allows installation processes to be made more flexible and adapted to different requirements in the field.
