nVent HOFFMAN S1MT250 is a 250 mm anodised aluminium light operator arm profile with a 75 × 55 mm closed section designed to provide structural support and internal cable routing for industrial HMI suspension systems.
£136.00
The nVent HOFFMAN S1MT250 is a compact 250 mm aluminium operator arm profile designed for the nVent HOFFMAN light swing arm system. It provides structural support for suspended HMI enclosures, operator panels and machine-control interfaces while also acting as a protected conduit for equipment wiring.
Manufactured from aluminium with an anodised finish, the S1MT250 combines low weight with the structural integrity required for industrial operator-interface installations. The profile attaches to compatible system components using six setscrews at each end, with the setscrews supplied with the corresponding couplings rather than the tube itself. This connection method allows straightforward adjustment and levelling during installation.
The S1MT250 has a length of 250 mm and a compact 75 × 55 mm external profile, with a weight of approximately 0.79 kg. Its short length makes it particularly suitable for compact HMI installations and suspension arrangements where only a small extension between joints, brackets or enclosure couplings is required.
Operator arm profiles form the structural backbone of industrial HMI suspension systems, supporting control enclosures while providing a protected route for power, control and communication wiring. The nVent HOFFMAN S1MT250 provides a compact 250 mm section that can be combined with compatible brackets, elbows, joints and panel couplings to create application-specific operator-interface support arrangements.
The light swing arm system combines aluminium profiles with modular connection components to provide flexible HMI positioning for industrial machinery. The S1MT250 is particularly useful where a short suspension section is required, while its internal cable passage helps maintain a clean installation without external wiring along the operator arm.

The S1MT250 is an aluminium operator arm profile used as a structural tube within nVent HOFFMAN light swing arm systems, supporting operator enclosures while also providing an internal route for equipment wiring.
The S1MT250 has a nominal length of 250 mm and an external profile measuring 75 × 55 mm.
The S1MT250 is manufactured from aluminium and features an anodised finish, providing a strong yet lightweight structural component for industrial HMI suspension systems.
Yes. The aluminium profile provides structural support while also acting as a conduit for electrical, control and communication wiring between compatible suspension-system components and the attached HMI enclosure.
The profile attaches to compatible system components using six setscrews at each end. The setscrews are supplied with the system couplings rather than the tube and allow adjustment and levelling during installation.
nVent HOFFMAN light swing arm components provide machine builders and automation engineers with strong, lightweight and configurable structural support for suspended HMI enclosures, operator panels and industrial machine-control interfaces.
