Wirable sockets for energy supply for field modules are a product category rather than a specific brand, commonly used in industrial automation and control systems. These components are typically manufactured by companies specializing in electrical connectors and industrial equipment, such as Phoenix Contact (Germany), Weidmüller (Germany), or TE Connectivity (Switzerland/USA). These sockets are designed to provide reliable power connections for modular field devices in harsh environments, serving industries like manufacturing, process automation, and machinery. Key features often include IP-rated protection, quick-connect functionality, and compatibility with various fieldbus systems.
