Siemens 6ES7 972-0BA12-0XA0 Profibus Connector

Siemens 6ES7972-0BA12-0XA0 SIMATIC DP PROFIBUS bus connector is an RS-485 interface for PROFIBUS DP networks operating up to 12 Mbit/s. It features a 90-degree cable outlet for space-efficient panel mounting and includes a terminating resistor with isolating function to maintain signal integrity at the end of a bus segment. The unit is specified without a PG socket, meaning there is no programming port built in. Its compact enclosure measures 15.8 x 64 x 35.6 mm (W x H x D), enabling installation in tight control panels or enclosures. This bus connector provides the PROFIBUS DP connection between DP devices and the RS-485 trunk in Siemens SIMATIC NET configurations, supporting standard PROFIBUS cabling and components and enabling reliable data exchange on networks up to 12 Mbit/s. Commonly sourced as the 6ES7972-0BA12-0XA0 bus connector in Siemens Industry Mall catalogs, it is designed to serve as the edge interface between PROFIBUS DP devices and the RS-485 bus in SIMATIC automation setups.
