Rack Enclosures
Rack enclosures (rack cabinets, laboratory enclosures) are used to house standard 19 in. rack-mounted components or other standard-sized devices. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants such as dust and water.
Industrial Enclosures
Industrial enclosures are used to house electronic components, equipment and devices. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants.
Modular Enclosures
Modular enclosures consist of smaller components that can be assembled to create custom enclosures, often for temporary or mobile systems. These modular components are available in standard sizes and allow modular enclosures to be used for a variety of purposes.
Pushbutton Enclosures
Pushbutton enclosures are designed to house and protect electronic panels, controls, and components and while allowing functionality through pushbuttons on the surface. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants such as dust and water.
Terminal and Junction Boxes
Terminal and junction boxes are used to house electrical components and facilitate wiring.
