At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7972-0BA12-0XA0 |
| Product Type | PROFIBUS bus connector |
| Core Function | Screw-wired RS 485 station attachment |
| Application | PROFIBUS network devices |
Screw-clamped bus wires
The incoming and outgoing bus conductors connect through the screw-terminal arrangement.
Right-angle routing
The 90-degree cable outlet requires the appropriate space beside the device connector.
Integrated termination
A slide switch connects the terminating-resistor network at a segment endpoint.
Product Overview
6ES7972-0BA12-0XA0 provides a right-angle, screw-wired connection between a PROFIBUS station and its bus cable.
The connector has no programming socket and uses the integrated termination with isolating function to distinguish an endpoint from an ordinary through connection.
Key Functions
Secure the two bus-cable runs
Two cable connections accommodate the incoming and outgoing PROFIBUS line with screw-terminal conductor clamping.
Attach to the station interface
The nine-pin sub-D device plug is retained by its screwed joint.
Set endpoint or through operation
The termination setting connects the internal resistors and determines whether the outgoing line remains connected.

Frequently Asked Questions
Is 6ES7972-0BA12-0XA0 a FastConnect insulation-displacement connector?
No, the PROFIBUS conductors are connected with screw terminals.
Can I connect both an incoming and an outgoing bus cable at 6ES7972-0BA12-0XA0?
Yes, the connector provides two electrical connections for PROFIBUS cables.
Will 6ES7972-0BA12-0XA0 fit a location that requires a 35-degree cable outlet?
This version has a 90-degree cable outlet, so the installation must provide clearance for right-angle routing.
Does 6ES7972-0BA12-0XA0 provide a service socket for a PG?
No, the connector is the version without a programming-device socket.
Can 6ES7972-0BA12-0XA0 operate in an unheated cabinet at −20 °C?
Yes, −20 °C is within its specified −25 to +60 °C operating range.
How can the housing of 6ES7972-0BA12-0XA0 be secured to the station interface?
The connector uses a screwed joint to lock it to the device interface.
What should I check if following PROFIBUS nodes disappear after switching termination on at 6ES7972-0BA12-0XA0?
Check that the switch was enabled only at the intended segment end because the isolating function disconnects the outgoing bus cable.
