The SIEMENS 6ES7972-0BA42-0XA0 is a SIMATIC DP connection plug for PROFIBUS networks designed for reliable communication at up to 12 Mbit/s. Its compact footprint (15.8 x 54 x 39.5 mm) and inclined cable outlet make wiring in tight panels easier, while the built-in terminating resistor with isolating function simplifies network termination and fault isolation. Supplied without a PG socket, it suits installations where a dedicated programming connector is not required, offering a space-saving and practical solution for PROFIBUS segment connections.
