Data line chokes ensure interference-free signal transmission in communication and bus systems. In the age of Industry 4.0, machines, servers and computers communicate with each other and will do so more and more frequently in the future. Where individual machines used to work independently in the production process, entire machine parks now function as one networked unit. Interference-free signal transmission with the help of data line chokes is therefore essential. Different designs, for example as SMD, are possible at Beckmann.
