Why Choose the nVent HOFFMAN S1MFC HMI Flange Coupling?
The nVent HOFFMAN S1MFC is a robust HMI flange coupling designed to connect a suspension tube directly to an operator-interface enclosure while allowing controlled rotational movement. As part of the nVent HOFFMAN SYSPEND 180-MAX suspension system, it provides a secure mechanical connection for industrial HMI installations, machine controls and suspended operator stations.
The S1MFC enables the connected enclosure to rotate through 300 degrees and can be locked into a selected position for convenient operator access. It incorporates a safety stop and maintenance-free bearings for dependable long-term operation, while its die-cast aluminium construction provides the durability required for industrial suspension-system applications.
With a height of 174 mm and a depth of 125 mm, the S1MFC provides a compact interface between the suspension tube and enclosure. It is finished in RAL 9005 black and supplied with installation instructions, gaskets, tube setscrews and enclosure mounting hardware for straightforward integration with compatible SYSPEND 180-MAX components.

Flexible Support for Industrial HMI Systems
Industrial HMI suspension systems provide a flexible way to position operator panels, control enclosures and machine interfaces close to the point of use. A flange coupling such as the nVent HOFFMAN S1MFC creates the connection between the suspension tube and enclosure while allowing the operator interface to rotate for improved visibility and accessibility.
The SYSPEND 180-MAX system is designed for demanding industrial machine-control applications and uses modular suspension components to create configurable support structures. The S1MFC combines rotational movement, position locking and a robust mounting flange to help provide a secure and practical interface between the suspension system and HMI enclosure.
