Q1: What is the Siemens 6ES7972-0BA12-0XA0?
It is a PROFIBUS DP bus connector with a 90° right-angle cable outlet and screw terminals. It is used to connect PROFIBUS nodes to the bus cable in industrial automation networks .
Q2: What is the difference between this and the 6ES7972-0BB12-0XA0?
The 0BA12 (this item) has no PG socket. The 0BB12 includes a PG socket for connecting a programming device or operator panel without disconnecting the bus .
Q3: Does this connector use FastConnect technology?
No. This is the screw terminal variant. FastConnect insulation displacement connectors carry different part numbers (e.g., 6ES7972-0BA52-0XA0) .
Q4: Does this connector have a terminating resistor?
Yes. It has an integrated terminating resistor that is activated via a slide switch. When activated, the isolating function disconnects the outgoing bus segment to prevent signal reflection .
Q5: When should I activate the terminating resistor?
Activate the terminating resistor only when the connector is at the first or last physical node of the PROFIBUS segment. In all other positions, the terminating resistor must be off .
Q6: What transfer rates does this connector support?
It supports PROFIBUS transfer rates from 9.6 kbit/s to 12 Mbit/s .
Q7: What is the cable outlet orientation?
It has a 90° right-angle cable outlet, routing the cable parallel to the device face .
Q8: Is this connector suitable for hazardous areas?
Yes. It carries ATEX, FM, CCC-Ex, and IECEx approvals for hazardous locations, in addition to UL and marine certifications .
Q9: What are the dimensions and weight?
Dimensions are 15.8 × 64 × 35.6 mm (W × H × D). Net weight is 36 g .
Q10: What is the operating temperature range?
The connector operates from -25 to +60 °C .
Q11: Does this connector have strain relief?
Yes. It includes integrated strain relief to protect the cable connection from mechanical stress .
Q12: What should I verify before ordering?
Always verify the exact part number (6ES7972-0BA12-0XA0 for 90° screw terminal without PG), confirm your application does not require a PG socket (consider 6ES7972-0BB12-0XA0 if it does), and ensure your PROFIBUS cable is compatible with screw terminal connection (not FastConnect).
