Suspension Positioning Arms for Enclosures


Example Configuration	All Components Sold Separately

Example Configuration

Hang your human-machine interface and swivel it around to save floor space and comfortably access touch screens, buttons, and other operating equipment. These suspension arms have already-drilled mounting holes that match our HMI enclosures. Route wire from your HMI components to a machine through a hole that runs through the entire arm. To prevent them from swinging too far and hitting people and equipment, locking pins let you restrict how far these arms rotate. Brakes lock their position into place.

Customize a system for your application—you can create hundreds of different variations. A complete suspension arm requires at least a base, a tube, and a mount. Add components to extend your arm up to 80” from the base and expand its range of motion. Arms without a connector support up to 180 lbs. Those with a connector support up to 135 lbs., but the load it can hold decreases by 2 lbs. for every 1” over 40” from the base.

Bases


Wall Mount	Bench Top

Bases mount your arm to a surface.

Wall Mount—Wall bases mount to a wall, the side of a machine, or another vertical surface.

Bench Top—Bench-top bases mount to horizontal surfaces, such as the top of a machine.

Watertight Enclosures for Positioning Arms


Enclosure, Handles, and Keyboard Tray (HMI Not Included)

Create a human-machine interface (HMI) that mounts to a positioning arm so you can move it exactly where you need it. The mounting holes in these enclosures align with our positioning arms, while the large center hole lets you route cables from your external HMI components. If you want to mount these enclosures to something else, add a plug to seal the existing holes and drill your own. Use the back cover to service your HMI without taking the enclosure apart or removing it from its mount. Whether mounted to a positioning arm or sealed with a plug, these enclosures safeguard power supplies and wiring from a range of drips to drenches.

Powder-Coated Steel—Inherently strong, these enclosures resist denting and cracking better than our other metal options. The coating forms a barrier against water and mild detergents, but if scratched, the underlying steel may rust.
