Siemens SIMATIC Series Bus Connector, IP20, Profibus DP Connector Type - 6ES79720BA700XA0


This bus connector provides a Compact Interface for linking PROFIBUS stations to a PROFIBUS bus cable within SIMATIC DP installations. It delivers a right-angled cable exit and supports RS‑485 FastConnect wiring for fieldbus networks up to 12 Mbit/s. The enclosure is silicone‑free and designed for panel or device mounting where a detachable PG socket is not required.

Features & Benefits


• FastConnect insulation displacement reduces wiring time and errors
• Integrated switchable terminating resistor enables inline bus isolation
• 9‑pin sub‑D port simplifies connection to network equipment
• Rated IP20 for protected indoor control‑cabinet environments
• Operates from −25°C to +60°C for typical industrial conditions

**Applications**


• Suitable for connecting distributed I/O modules to PROFIBUS trunks
• Ideal for retrofit of control panels using SIMATIC DP components
• Used with PROFIBUS cable runs requiring 90° cable routing
• Can be used for fieldbus segments needing switchable termination

How does the terminating resistor function during network reconfiguration?


A slide switch activates a built‑in resistor combination

when engaged it isolates the outgoing bus, allowing safe disconnection and reconfiguration without removing the connector.

What cable types does the connector accept for FastConnect?


The contact system accepts two‑core PROFIBUS FastConnect installation cables via integrated insulation displacement contacts, removing the need to strip conductors.

How is mechanical fixation achieved on equipment?


The housing is secured with a screwed joint and includes strain relief to maintain cable retention under mechanical load.
