New Product | IO-Link Master with M12 L-coded Power Port

In modern industrial automation, high-protection master modules play a crucial role. As industrial systems increasingly evolve towards decentralization, these modules not only provide reliable data transmission and device control capabilities but also maintain stable operation in harsh industrial environments.

The trend towards decentralization emphasizes the distribution of traditional applications and components, typically housed in control cabinets, into field devices, enabling them to operate as part of smaller equipment or machines. This approach aligns with the "cabinet-free" concept, enhancing system flexibility and reliability. High-protection master modules, with their superior dustproof, waterproof, and impact-resistant features, have become an indispensable part of industrial automation systems.

Differences Between L-coded and 7/8” Interfaces

Choosing the right power interface is critical in industrial automation. Different types of interfaces offer distinct advantages in various applications. L-coded and 7/8” are two common power connectors in industrial automation, each with significant differences:

Current Carrying Capacity

The design of the L-coded interface allows it to carry higher currents, primarily due to optimized contact design, high-quality material selection, and thermal management. The L-coded interface can handle currents up to 16A and features an IP67 or higher protection rating.

The 7/8” interface typically handles a maximum current of 12A and is known for its reliability, widespread compatibility, and high protection level.

Shape and Size

The L-coded interface, with optimized contact design, high-quality materials, and carefully designed thermal mechanisms, supports higher currents in a compact M12 size, providing efficient power connections in modern industrial applications. In contrast, the 7/8” interface, though larger, focuses on stability and compatibility with traditional industrial applications.

Application Scenarios

L-coded Interface

Due to its high current transmission (up to 16A) and high protection rating, the L-coded interface is more suitable for high-power industrial robots, servo drives, automated production lines, and intelligent warehousing systems that require high power transmission in industrial automation.

7/8” Interface

The 7/8” interface is suited for applications with medium power requirements (up to 12A), such as PLCs, sensors, and medium-sized industrial machinery. It is applicable in industries like industrial automation, logistics equipment, food and beverage industry, factory automation, and building automation.

SENTINEL L-coded IO-Link Master

The newly launched L-coded IO-Link master series from SENTINEL combines a high-strength plastic housing with metal connectors, providing impact and vibration resistance. The electronic circuits are encapsulated with resin, achieving an IP67 high protection rating, ensuring reliable operation even in harsh environments.

Product Features

L-coded Power Supply

SENTINEL's L-coded design not only enhances the reliability of the power supply but also simplifies the installation process. The L-coded connectors can handle currents up to 16A and have an IP67 high protection rating, performing excellently in harsh environments. Its standardized design complies with international standards (such as IEC 61076-2-111), ensuring compatibility and interoperability between products from different manufacturers. The more compact size, compared to the 7/8" connector, reduces space usage by approximately 30%, making it more flexible in space-constrained applications.

Dual Ethernet Ports

The dual D-coded M12 Ethernet ports with a built-in switch support 100Base-TX transmission, with a maximum transmission rate of 100Mbit/s. This design not only increases data transmission speed and stability but also enhances system flexibility and reliability. The dual-port configuration makes it easier and more reliable to connect devices within a network, suitable for various complex industrial network environments.

IO-Link Interface

The L-coded IO-Link master series offers multiple interface configurations, including 8 A-class ports, as well as a combination of 4 A-class ports and 4 B-class ports. This diverse interface configuration supports various device connections, providing greater flexibility and scalability.

Support for Multiple Protocols

This series is compatible with multiple industrial communication protocols, such as Profinet, EtherCAT, and CC-Link IE Field Basic. This compatibility ensures broad applicability in different industrial automation systems, improving system interoperability and flexibility.

Conclusion

The L-coded IO-Link master series from SENTINEL, with its reliable technology, high protection rating, and flexible interface configuration, provides strong support for industrial automation systems. Whether in demanding environments or complex networks, these products can operate stably and reliably. We believe these products will be an excellent tool in achieving your industrial automation goals.
