nVent Hoffman SYSPEND 281 Pendant Arm System
HMI enclosures are designed specifically for the wide range of Human Machine Interface applications found in industrial settings. It is important to have customization options like removable front plates that allow for easy installation of HMI components, optional door panels that can be mounted anywhere and cutout options where needed. Some enclosures are designed to enclose, protect and suspend lightweight HMI devices. HMI enclosures should always be rated to protect sensitive systems from the sometimes harsh environments found in industrial settings. This would include protection against moisture, chemicals and dirt, as well as, temperature variations.
nVent Hoffman SYSPEND 281-MAX pendant arm system supports up to 281 pounds at 3.3 feet and allows users to easily move controls into and out of position. The vertical motion pedestal tubes provide height-adjustable solutions for pedestal mounting. SYSPEND 281-MAX is recommended for use with SYSPEND Aluminum HMI enclosures and CONCEPT HMI enclosures.

nVent Hoffman SYSPEND aluminum HMI enclosure is designed to accommodate touch-screen HMI devices. The single-walled aluminum reduces the overall weight of the enclosure and provides increased heat dissipation. The enclosure can be mounted on a pendant or pedestal and the integrated side handles allow for easy repositioning.
nVent Hoffman CONCEPT HMI landscape-oriented steel enclosures are ideal for applications that utilize flat-screens, pushbuttons and other similar devices. These enclosures are made of light gray, 14 gauge steel and have a range of customization options. The enclosures have a predrilled hole in the top for pendant arm mounting and be can mounted on a pedestal when inverted. The removable front plate allows for easy installation of HMI components and the enclosure accommodates cutouts anywhere they are needed. Comfort grip handles extend the length of the profile and a hinged rear door has a single-point latch.
HMI vs OIT, What's the Difference?
Human Machine Interface (HMI) is a software interface that allows operators to interact with various pieces of electrical hardware and controls systems. HMI typically utilizes monitors or screens to display information, which are referred to as HMI screens. The screens are not the actual HMI, but are a tool used to display HMI software. For example, electrical enclosures often have screens mounted on the outside of them to provide users with information about ongoing process and to allow users to make changes to the system.
Operator Interface Terminal (OIT) typically displays basic information about the electrical hardware that it is attached to. It provides only local information about the environment it is interfacing with and allows control and monitoring for that one piece of hardware, not an entire system.
