6ES7972-0BA42-0XA0

Product information

The 6ES7972-0BA42-0XA0 is a Siemens PROFIBUS bus connector, RS 485, screw terminals, without programming port, 35° cable outlet. It connects PROFIBUS stations to the bus cable and supports transfer rates from 9.6 kbit/s up to 12 Mbit/s.

The terminating resistor is an integrated resistor combination that can be connected via a slide switch, the enclosure is plastic with a screwed joint locking mechanism, and the connector is rated for ambient temperatures of −25 to +60 °C during operation. The 35° cable outlet is the angled variant, which is what makes it suitable where cabinet depth or cable routing calls for a slanted entry.

Choosing the right PROFIBUS connector

PROFIBUS connectors are not interchangeable across all situations, and the differences are in the cable outlet angle and whether a programming port is present:

• 35° outlet, screw terminals, without programming port — this article number
• 90° outlet, Fast Connect, without programming port — 6ES7972-0BA52-0XA0
• 90° outlet, Fast Connect, with programming port — 6ES7972-0BB52-0XA0

Typical applications

• Wiring PROFIBUS DP stations where cabinet layout favours a 35° cable entry
• Connecting drives, remote I/O stations and controllers to a PROFIBUS DP network
• Bus termination at the physical end of a PROFIBUS segment, using the integrated resistor
• Replacement of damaged connectors on existing PROFIBUS installations

Application examples describe typical uses of this product type. Suitability for your own installation must be confirmed against your engineering documentation.
