Consistent connection technology in Industry 4.0

Industry 4.0 automation and production concepts require scalable and adaptable automation solutions. This enables the easy installation and removal of distributed modules. The same applies to the connection technology: the decisive factors for PCB terminal blocks and PCB connectors are a wide variety of connection technology and mounting options, as well as uniform interfaces for a consistent standard. This makes it possible to reduce maintenance and storage costs.

Connection technology for the transmission of data, signals, and power

Electronic devices in industrial applications are subject to constantly growing demands. The trend is toward miniaturization: space-saving terminal blocks and PCB connectors must allow for more electronics in the smallest possible space in the control cabinet or in other applications. The components need to be more compact and the connection technology needs be more powerful, resilient, and flexible.
Phoenix Contact meets these requirements with its comprehensive product portfolio. The IP20 connection technology enables device manufacturers to create optimum connections for data, signal, and power transmission. Boasting more than 10,000 different products, the comprehensive portfolio provides the right connection for every application.
