Siemens 6ES79720BB50-0XA0 Simatic DP Bus Connector

Siemens 6ES7972-0BB50-0XA0 SIMATIC DP Bus Connector is a PROFIBUS DP interface component that terminates and links a PROFIBUS DP bus cable to network devices at speeds up to 12 Mbit/s. This 90-degree outlet connector employs IPCD (insulation-displacement) FastConnect technology for fast, screwless wiring and includes a PG socket for programming and diagnostics. It is designed for SIMATIC DP networks, enabling reliable connection between a PLC, I/O blocks, and other field devices on the PROFIBUS DP bus. As part of the 6ES7972 bus connector family, the 0BB50 variant is intended for DIN-rail or panel mounting in industrial control panels, offering a compact footprint suitable for cabinets with tight space. The device supports standard PROFIBUS DP interfaces and aligns with RS-485 electrical characteristics used by PROFIBUS DP, providing a robust solution for factory floor automation. The article number 6ES7972-0BB50-0XA0 identifies this model within Siemens' catalog and confirms compatibility with other SIMATIC DP components in a single DP network, making it a suitable choice when adding an additional bus connection point or replacing a failing DP bus connector in existing systems.
