6ES7972-0BB12-0XA0 SIMATIC PROFIBUS 90° Screw Bus Connector with PG Socket
A right-angle screw-terminal PROFIBUS connector with a PG socket, integrated strain relief and switchable termination for the bus-segment endpoints.
At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7972-0BB12-0XA0 |
| Product Type | PROFIBUS station connector |
| Core Function | Bus connection and commissioning access |
| Application | SIMATIC DP RS 485 station wiring |
Screw-terminal bus contacts
The two bus-cable connections use the screw-wired conductor arrangement.
PG service connection
The fitted programming-device socket remains available beside the permanent bus wiring.
Right-angle profile
The 90-degree cable outlet fits the intended S7 station interface arrangement.
Product Overview
6ES7972-0BB12-0XA0 provides the screw-terminal 90-degree PROFIBUS connection with an additional PG socket.
The connector combines an integrated switchable resistor network, cable strain relief and screwed retention at the station interface for a serviceable RS 485 cable connection.
Key Functions
Attach incoming and outgoing bus cables
Two PROFIBUS cable connections provide the through-wiring path at a non-terminating node.
Keep programming access available
The PG socket supports local commissioning access without selecting a no-PG connector.
Retain and terminate the installed connection
The screwed joint secures the connector and the slide switch activates the integrated terminating resistor network.

Frequently Asked Questions
Which wiring method distinguishes 6ES7972-0BB12-0XA0 from a FastConnect plug?
This connector clamps the bus conductors with screw terminals rather than insulation-displacement contacts.
What should I do with the terminating-resistor switch on 6ES7972-0BB12-0XA0 at a segment endpoint?
Set the switch to ON at the first or last bus node and keep the supplying station powered.
Can a looped-through 6ES7972-0BB12-0XA0 be unplugged from a non-terminating station while the bus continues operating?
Yes, a connector with a looped-through cable can be removed from the device interface without interrupting bus data exchange.
Is the same unplugging procedure permitted for 6ES7972-0BB12-0XA0 with active end termination?
No, unplugging a connector with active termination at the cable end disrupts the bus.
How can I secure 6ES7972-0BB12-0XA0 to the station interface?
Tighten the connector’s screwed joint at the device interface.
Can I use 6ES7972-0BB12-0XA0 where commissioning requires a local PG socket?
Yes, this version includes the programming-device socket.
How much connector depth should I allow behind 6ES7972-0BB12-0XA0 before accounting for the cable bend?
The connector body depth is 35.6 mm.
