Siemens 6ES7972-0BA12-0XA0 Connection Plug for PROFIBUS DP

Siemens SIMATIC DP, 6ES7972-0BA12-0XA0, is a PROFIBUS DP connection plug designed for SIMATIC DP networks, supporting data rates up to 12 Mbit/s and featuring a 9-pin Sub-D (D-sub) interface for robust bus termination in PROFIBUS networks. The plug uses a 90° cable outlet to simplify routing in control cabinets, and its enclosure measures 15.8 x 64 x 35.6 mm (WxHxD); it includes a terminating resistor with isolating function and is the “without PG socket” variant. Used at PROFIBUS DP nodes to connect to the bus cable, it functions as the end connector in a segment and provides the terminating resistor with isolating function to maintain signal integrity and limit reflections along the line. The 0XA0 suffix identifies the version without a PG socket, and Siemens lists 6ES7972-0BA12-0XA0 among the PROFIBUS bus connector plugs up to 12 Mbaud, with related variants such as 6ES7972-0BB12-0XA0 offering different socket configurations.
