The Siemens 6ES7972-0BA30-0XA0 is a SIMATIC DP PROFIBUS bus connector with a 30° inclined cable outlet, designed for connecting PROFIBUS stations to the bus cable using Fast Connect insulation displacement terminals. It handles PROFIBUS DP transfer rates from 9.6 kbit/s up to 1.5 Mbit/s, which covers the standard baud rates for most distributed I/O and drive networks on a PROFIBUS line.
At 15 mm wide, 57.6 mm tall, and 39.5 mm deep, this connector sits tight on a DIN rail inside an IP20 enclosure — typical for a control cabinet backplane. The 30° cable outlet keeps the PROFIBUS cable routed low against the panel, which helps with bend radius and gland-plate fill factor when you're stacking multiple connectors on a segment.
Wiring is via integrated insulation displacement terminals for 2-core PROFIBUS FC installation cables — no stripping, just punch down with the Fast Connect tool. The connector has no integrated terminating resistor and no programming port; it's a straight pass-through for the bus signal. Locking is by screwed joint to the Sub-D connector, so it won't vibrate loose on a machine.
UL approved and RoHS conformant, with a silicon-free designation that matters for paint or coating line environments where silicone outgassing can cause surface defects.
