Siemens 6ES7972-0BA40-0XA0 Profibus Connector

Siemens 6ES7972-0BA40-0XA0 SIMATIC DP PROFIBUS bus connector provides a PROFIBUS DP interface based on RS-485 for networks up to 12 Mbit/s, linking PROFIBUS DP devices in Siemens automation systems. It features a tilted outgoing cable and a compact 16 x 54 x 34 mm footprint, enabling clean routing and easy mounting in control panels or equipment enclosures. A terminating resistor with an isolation function is included to improve signal integrity at the end of a PROFIBUS segment, while the device is specified without a programming port (PG) socket, distinguishing it from variants that provide a programming interface. Designed for SIMATIC DP networks, this connector is typically used to connect masters to slaves such as drives, I/O modules, and other PROFIBUS DP devices, delivering a robust, space-efficient bus connection that supports dependable operation in industrial environments.
