The Siemens 6ES7972-0BB61-0XA0 is a SIMATIC DP PROFIBUS bus connector for RS-485 networks, using Fast Connect insulation displacement terminals to terminate 2-core PROFIBUS FC installation cables without stripping. The 35° cable outlet keeps the cable routed low-profile against the panel wall, which matters in a crowded enclosure where right-angle connectors would bump adjacent modules. It includes a PG programming port so you can plug a programmer into the same node without breaking the bus.
The transfer rate spans 9.6 kbit/s to 12 Mbit/s, covering the full PROFIBUS DP speed range — no limitation on baud rate for a mixed-speed segment. The 9-pin sub D connector mates with standard PROFIBUS DP device ports. IP20 means it's for use inside a control cabinet, not in wet or dusty field locations.
Panel integration
The connector body measures 15.8 mm wide, 54 mm high, and 39.5 mm deep — a slim footprint that fits between adjacent modules in a SIMATIC S7-300 or ET 200M rack without blocking neighboring slots. The strain relief is built in, and the FastConnect method means you terminate the cable by pressing it into the slot; no screwdriver needed for the bus wires. The PG socket accepts a standard 5-pin programming cable for commissioning.
