Siemens 6ES7972-0BA12-0XA0 Profibus Bus Connector

Siemens 6ES7972-0BA12-0XA0 is a PROFIBUS DP bus connector (connection plug) designed for use in SIMATIC DP networks, supporting PROFIBUS data rates up to 12 Mbit/s and featuring a 9-pin Sub-D connector for RS-485‑style bus signaling. It offers a 90-degree cable outlet for compact installation, an integrated terminating resistor with isolating function, and a plastic housing, with overall dimensions of 15.8 x 64 x 35.6 mm (WxHxD); this variant includes no PG programming socket. Ideal as either an end or intermediary link in PROFIBUS segments, it is used to attach DP nodes such as slaves or interface components to the bus, enabling reliable termination and straightforward integration in industrial automation environments.
