6ES7972-0BA41-0XA0 SIMATIC PROFIBUS 35° Screw Bus Connector without PG Socket
A screw-terminal connector with a 35-degree cable outlet, no PG socket and integrated termination that disconnects the outgoing line when enabled.
At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7972-0BA41-0XA0 |
| Product Type | RS 485 station connector |
| Core Function | Inclined bus-cable connection |
| Application | PROFIBUS station wiring |
Inclined station connection
The bus cable follows a 35-degree outlet from the station interface.
Direct screw termination
Four wire terminals accept conductors up to 1.5 mm².
Segment-end selection
The internal termination and disconnect function are controlled together.
Product Overview
6ES7972-0BA41-0XA0 connects an RS 485 PROFIBUS station with an inclined screw-wired bus cable and no local programming socket.
The integrated terminating-resistor and disconnect arrangement allows the physical cable endpoint to be selected while the normal through position keeps the following bus cable connected.
Key Functions
Clamp the bus conductors
The connector uses four screw terminals for the incoming and outgoing bus wires.
Define the end of the electrical segment
Switching in the terminating resistor also isolates the outgoing cable from the bus.
Disconnect an interior station from its connector
A non-terminating station may be disconnected without breaking the cable path through the connector.

Frequently Asked Questions
Can I use 6ES7972-0BA41-0XA0 where the bus cable must leave at an inclined angle?
Yes, its cable outlet is inclined at 35 degrees.
Does 6ES7972-0BA41-0XA0 include a second socket for commissioning access?
No, this connector has no PG socket.
What conductor limit applies to the screw terminals in 6ES7972-0BA41-0XA0?
The four bus-wire screw terminals accept conductors up to 1.5 mm².
Can I remove an interior station from 6ES7972-0BA41-0XA0 without opening its bus-wire terminals?
Yes, a station can be disconnected from the bus connector without interrupting bus traffic when that connector is not supplying required endpoint termination.
How much current must the station reserve for 6ES7972-0BA41-0XA0?
The connector draws a maximum of 5 mA from the station-supplied 4.75–5.25 V DC connection.
Can 6ES7972-0BA41-0XA0 be stored at −30 °C?
No, the specified transport and storage range starts at −25 °C.
Why can activating the termination switch on 6ES7972-0BA41-0XA0 isolate subsequent devices?
The switch disconnects the outgoing bus cable whenever the integrated terminating resistor is enabled.
