Siemens 6ES7-972-0BB52-0XA0 Bus Connector For S7-300

Siemens 6ES7-972-0BB52-0XA0 is a PROFIBUS bus connector plug for the SIMATIC S7-300 backplane, enabling a PROFIBUS DP network to interface directly with the CPU module and its rack-mounted I/O. It supports PROFIBUS DP communications up to 12 Mbit/s, uses FastConnect insulation displacement technology for fast, reliable terminations, and features a 90-degree cable outlet to simplify routing in tight control panels. The assembly includes a PG socket for connecting a PC adapter or programming interface, and its physical footprint measures 15.8 x 59 x 35.6 mm (W x H x D). This bus connector is part of Siemens’ SIMATIC connectivity family and is commonly used to link PROFIBUS DP devices to S7-300 controllers in industrial automation environments, providing a robust, space-efficient bus interface for DP networks.
