Product Overview
The Siemens 6AV7674-1KF00-0AA0 Round Pipe Adapter For PRO Devices is a mechanical mounting accessory for Siemens SIMATIC HMI PRO devices prepared for an extendable support arm with a round-tube connection. It provides the interface between the HMI mounting point and the support arm, allowing the operator panel to be installed in a suitable position near a machine, production cell, or industrial workstation.
In many industrial installations, the HMI needs to be positioned where operators can monitor production status and access machine controls without standing directly beside the electrical cabinet. A support-arm arrangement allows the panel to be mounted above the work area, beside a machine enclosure, or at the end of an articulated mounting structure. The adapter establishes the mechanical connection needed for this arrangement.
The 6AV7674-1KF00-0AA0 is specified for the transition from a size-48 round tube to a flange plate compatible with the basic adapter interface. Its steel construction with a powder-coated RAL 9006 finish suits the mechanical mounting requirements of industrial HMI installations. The adapter is intended for PRO devices prepared for the corresponding support-arm connection; it should not be assumed compatible with every SIMATIC HMI panel or every support-arm design.
The adapter’s upper interface uses a ring groove and set-screw fastening arrangement to secure the compatible PRO device. At the lower end, the mechanical interface connects to the support-arm structure. Correct engagement at both interfaces is essential because the mounting assembly must support the panel while maintaining its intended position during routine operator interaction.
This component is particularly relevant when a machine builder is assembling a fully enclosed HMI workstation and needs the panel mounted on a support arm rather than directly on a cabinet door. The adapter handles the mechanical transition; it does not provide electrical communication, display functionality, or control logic.
Before installation, confirm that the HMI is prepared for the specified round-tube support-arm arrangement and that the supporting structure uses the matching interface. The installed assembly must also preserve the protection requirements of the complete PRO device mounting system.

Working Principle
The 6AV7674-1KF00-0AA0 works as a mechanical interface rather than an electronic component. Its function is to connect two mounting arrangements with different geometries: the round-tube support-arm structure and the flange interface used by the compatible PRO device mounting system.
Support Arm → Round-Tube Interface → Adapter Body → Flange Interface → PRO HMI Device
The lower interface engages with the matching support-arm connection. Once correctly fitted, the adapter provides the mounting point for the HMI device. At the upper end, the ring groove allows the compatible PRO device to be secured using set screws according to the applicable assembly procedure.
When the HMI is installed, the adapter transfers the mechanical load from the panel into the support arm. The complete assembly must be suitable for the panel’s load and the forces generated by operator interaction. The support arm, connecting hardware, and mounting surfaces therefore need to be checked as a complete mechanical system.
The adapter does not compensate for an incompatible support arm or an unsuitable mounting structure. Incorrect interface dimensions, loose fastening hardware, or improper engagement can cause movement at the joint. During installation, the mating surfaces and fastening points should be inspected before the HMI is placed into service.
The specified IP65 all-round protection applies when the adapter is correctly installed in the intended system. Maintaining that protection depends on the compatible HMI, the mounting interfaces, and the installation procedure. The adapter should not be treated as an independent electronic enclosure or as a substitute for the sealing requirements of the complete PRO assembly.
Role in a Siemens SIMATIC HMI PRO Mounting System
The round pipe adapter forms the mechanical connection between the HMI and its support-arm mounting structure. It allows a compatible PRO device to be positioned at the operator’s working location while keeping the display and control interface separate from the main machine cabinet.

Technical FAQs
Which HMI devices can be mounted with the 6AV7674-1KF00-0AA0 adapter?
It is intended for Siemens PRO devices prepared for an extendable support arm with a round-tube connection. Confirm the exact HMI model and mounting preparation before installation, because not every SIMATIC HMI panel uses the same mechanical interface.
What is the difference between this adapter and the basic adapter?
The 6AV7674-1KF00-0AA0 provides the round-tube-to-flange mounting transition for the specified support-arm arrangement. The basic adapter serves as a different mechanical interface within the PRO mounting system. Their functions are related, but they are not interchangeable without checking the mounting design.
Does the adapter itself provide IP65 protection?
The specified IP65 all-round protection applies when the adapter is installed correctly in the intended compatible system. The protection level depends on the complete assembly and its interfaces, so correct installation and the relevant sealing arrangements must be maintained.
Can the adapter be used with any industrial support arm that has a round tube?
No. The round-tube connection, flange interface, fastening arrangement, and load requirements must match. A support arm with a similar-looking tube may still have an incompatible mechanical interface. Check the support-arm specification and the HMI mounting requirements before assembly.
