Product Description

Beckhoff produces the EK1122, a crucial part of industrial automation systems. The EK EtherCAT Coupler Series includes this 2-port EtherCAT junction, which is essential for joining several EtherCAT network segments. In industrial settings, this little gadget facilitates dependable and effective data transport for a range of applications. The EK1122's capacity to speed up communication across vast distances is one of its most important features. Flexible network topologies are possible in big industrial environments with a maximum station distance of 100 meters. It is based on the mechanics of signal transmission in Ethernet connections. Long-distance electrical signals might deteriorate because of things like interference and attenuation, but the EK1122 guarantees dependable data transfer within its designated range. This is accomplished by using shielded Ethernet/EtherCAT cables (at least Category 5), which serve to preserve signal integrity and reduce signal deterioration.

High-speed communication between various automation system components is made possible by the EK1122's data transfer rate of 100 Mbit/s. As an Ethernet communication standard, the 100 Mbit/s rate guarantees compatibility with a wide range of systems and devices. Digital communication, which encodes data into electrical signals and transmits them as a sequence of bits, is the foundation of this capacity. A greater bit rate allows for speedier communication since it allows for the transmission of more data per second. With a small latency of around one µs, the EK1122 is another noteworthy characteristic. In automation systems, this low latency is essential to guaranteeing real-time responsiveness. Even little delays may have a big effect on productivity and efficiency in industrial operations where time is everything.

Data travel time via the coupler is reduced by the EK1122's minimum delay, which is made possible by its effective design and improved signal processing. Hot-connect capabilities, which enables segment connections and disconnections during operation without interfering with system operations, is another feature of the EK1122. The RJ45 sockets and the EtherCAT protocol provide the hot-connect feature, which allows the safe insertion and removal of devices while the system is switched on. Optimizing uptime and guaranteeing the uninterrupted functioning of industrial operations depend heavily on this skill. This concludes the EK1122's energy-efficient design, which has a typical current consumption of 220 mA. Wake Industrial gives consumers peace of mind and guarantees the EK1122's quality and dependability with a one-year warranty.
