binder Introduces knurled and hexagonal coupling rings
M12 connectors are a key component in modern automation solutions – wherever signals, data and power need to be transmitted reliably. At the same time, requirements for safe, consistent and high-quality field assembly are continuously increasing. binder addresses these demands with coupling rings of moulded, shielded M12 connectors which now feature a combination of knurling and hexagonal geometry.
Compared to previous designs, the new geometry enables assembly using tools such as torque wrenches for the first time. This allows users to achieve controlled tightening and benefit from increased process reliability as well as consistently high assembly quality – particularly in applications where defined torque is critical.
This design update directly reflects market demands: in many industrial environments, standardised and traceable assembly processes are becoming essential. By integrating a hexagonal feature, the connectors can now be tightened in a controlled manner, meeting common industrial specifications.
While the combination of knurling and hexagon is already established for unshielded versions, it is now extended to shielded M12 connectors. The result is a uniform design across different variants – a clear advantage for design engineers, installers and maintenance teams.
Beyond improved assembly capabilities, the new design offers practical benefits for everyday use. The combination of knurling and hexagon enables quick manual pre-assembly as well as precise final tightening with tools. This allows installation processes to be more flexible and better adapted to varying field requirements.
Typical application areas include automation technology – sensors & actuators, mechanical engineering and plant construction, as well as any environment where M12 connectors must be installed under defined mechanical conditions. Especially in applications with high vibration resistance and long-term stability requirements, controlled tightening provides an additional level of safety.
