In industrial automation, PROFINET systems are increasingly used for high-speed communication and data interaction between devices. However, when building such an efficient network system, a stable and reliable power supply is also critical. The M12 L-code passive junction box was born for this purpose.
Why choose M12 L-code?
The M12 L-code connection standard is designed for high-current DC power supply and supports a power transmission capacity of up to 16A and 63V, far exceeding traditional A and D coded connectors. It is very suitable for the power supply of PROFINET modules, remote I/O, sensor gateways and other devices.
Advantages of M12 L-code passive junction box
The M12 L-code passive junction box can quickly distribute the main power supply to multiple devices without active components, with a simple structure and easy installation. Through T-type or multi-port design, it can flexibly adapt to 4-port, 6-port, or even 10-port outputs, significantly simplifying field wiring.
Typical applications in PROFINET
- Connect multiple remote PROFINET modules or switches
- Power field devices outside the control cabinet
- With drag chain cables, suitable for dynamic equipment scenarios such as robots, transmission lines, etc.
