Siemens 6ES7972-0BB52-0XA0 SIMATIC NET PROFIBUS Connector 12 Mbit/s 90-Degree FastConnect

The Siemens 6ES7972-0BB52-0XA0 is a SIMATIC NET PROFIBUS bus connector for RS 485 networks up to 12 Mbit/s, with a 90-degree cable outlet and FastConnect insulation-displacement termination. It provides 2 electrical connections for PROFIBUS FC cable and a 9-pin sub-D output to the station, plus an integrated PG programming port. The plastic housing is IP20-rated with a screwed locking mechanism.

Selection Notes

The 90-degree cable outlet on this connector keeps the PROFIBUS cable running parallel to the DIN rail or cabinet wall, which matters in tight enclosures where a straight connector would foul the door or adjacent wiring. The integrated PG connection socket lets a PROFIBUS service tool tap the bus without disconnecting the FC cable, and the slide-switch terminating resistor avoids needing a separate terminator plug at line ends. Rated to 12 Mbit/s, it covers every standard PROFIBUS DP baud rate down to 9.6 kbit/s without a different part number per speed.

Applications

Typical uses include connecting PROFIBUS DP field devices, drives, and remote I/O stations to the bus cable in cabinets where clearance behind the connector is limited, and terminating bus segments using the built-in switchable resistor.
