Siemens 6ES7 972-0BA52-0XA0 Profibus DP Bus Connector

Siemens 6ES7972-0BA52-0XA0 SIMATIC DP Bus Connector is a PROFIBUS DP connection plug designed to terminate and bridge PROFIBUS DP cables to SIMATIC DP interfaces at speeds up to 12 Mbit/s. The unit uses a 9-pin Sub-D (D-sub) connector and FastConnect insulation-displacement technology for a space‑savvy, tool‑free connection that exits at a 90° cable outlet, ideal for tight control panels. It is specified as a RS-485 bus connector and is provided without a PG socket, aligning with Siemens’ FastConnect family for straightforward field installation. The physical envelope measures 15.8 mm (W) × 59 mm (H) × 35.6 mm (D), supporting compact mounting alongside other DP components. As part of the SIMATIC NET PROFIBUS portfolio, this plug enables direct interfacing between PROFIBUS DP master/slave devices and the DP network, serving as a reliable termination and junction point for DP segments without introducing a programming port. Typical applications include connecting a PROFIBUS DP device or module to a DP bus segment in industrial automation setups, such as packaging lines, material handling, or machine cells where Siemens PROFIBUS DP is deployed, ensuring clear, robust electrical connections for communications up to 12 Mbit/s. The 6ES7972-0BA52-0XA0 is a dedicated bus connector in the PROFIBUS DP ecosystem, designed to deliver stable RS-485 signaling and a compact form factor suitable for retrofits and new installations alike.
