Potting Boxes for Electronics

Potting boxes are commonly used for PCB potting or potting electronic assemblies. Potting cases are molded from ABS plastic or diecast aluminum and are available in a variety of sizes and styles. Potting boxes are a low cost, lightweight solution for your electronics project. Glue-on covers are available as an optional accessory on select series.

What Is a Potting Box for Electronics?

Unlike other types of enclosures, potting boxes are designed to be filled with potting compounds, a protective gel substance that cures to become solid. Once solid, this compound keeps electronic components safe from water, impacts, dirt, and other common environmental hazards.

Potting compounds can be made from several different substances, including epoxy and silicone, each having unique and useful protective qualities. Depending on the compound used, it can function as an electrical insulator, help manage heat inside an enclosure or even offer resistance to chemicals.

It’s common to see potting boxes used as parts within larger equipment, and they’re typically smaller than other types of electronic enclosures. However, they’re still perfectly capable of standing on their own, and many include options like mounting flanges for versatile performance in multiple applications.

When choosing a potting box for your application, one of the biggest challenges can be specifying a model that fits your needs. The best potting boxes are made from durable material that stands up to wear and tear, and it’s also important to find models with the right features. Finally, of course, you’ll want to look for potting box models that fit your budget.
