Enclosure Windows & Inspection Windows

Inspection windows for enclosures are an essential feature in many industrial and electrical applications, providing a convenient and safe way to monitor internal components without opening the enclosure. These windows are especially useful in environments where frequent access to the enclosure's interior for visual inspection or monitoring is necessary, but maintaining a sealed environment is crucial for safety and equipment integrity.

Typically, inspection windows are made of durable materials like polycarbonate, known for its strength and clarity. Polycarbonate windows are often chosen for their resistance to impact, UV radiation, and harsh environmental conditions. This makes them suitable for use in a variety of settings, including outdoor applications where exposure to sunlight and weather elements is a concern.

More Information about Enclosure Windows and Inspection Windows

The design of an inspection window is focused on ease of installation and a secure fit. Most window kits come with all necessary components and instructions, making them easy to install on existing enclosures. They are designed to fit seamlessly into the enclosure, maintaining its protective qualities, such as dust and water resistance. This integration ensures that the window does not compromise the enclosure's integrity and continues to protect the electrical components inside.

Inspection windows are available for both metallic and non-metallic enclosures. For steel enclosures, the window material and the installation process are designed to ensure a strong bond and a tight seal, preserving the enclosure's durability and protective properties. In the case of non-metallic enclosures, such as those made from plastic or fiberglass, the windows are similarly designed to align with the enclosure's material characteristics, offering clear visibility and robust protection.

The size and shape of inspection windows can vary, offering different viewing dimensions based on the enclosure's size and the user's requirements. This flexibility in design allows for a broad range of applications, from small control boxes to large industrial cabinets.

Inspection windows for enclosures are a practical solution for safely monitoring and inspecting internal components without compromising the enclosure's protective environment. Made from materials like polycarbonate, these windows are durable, UV-resistant, and designed to fit seamlessly into various types of enclosures, ensuring easy installation and a secure, clear view of the enclosure's interior.

FAQs

What details are important when selecting a place to install an inspection window?

When selecting a place to install an inspection window on an enclosure, it is crucial to choose a location that provides clear and unobstructed visibility of the key components inside, ensuring easy monitoring and inspection. Additionally, the chosen spot should not compromise the structural integrity of the enclosure or interfere with its protective features, such as its dust and water resistance, and should be accessible for maintenance without exposing the interior to environmental hazards or safety risks.

Maintain NEMA 4 Rating When Making Enclosure Penetrations

Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.

Devices mounted to the enclosure must have the same NEMA rating as the enclosure. 

This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure. 

Water tight conduit hubs must be used when running wire through a cutout in an enclosure. 

There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.

Bonded washers are necessary when mounting hardware to an enclosure. 

If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
