Product Information

Full details

The Hammond 1590A is an essential tool for electronics hobbyists, DIY pedal builders, and engineers looking for a compact, rugged housing for their circuitry. Its primary benefit is providing a robust, lightweight, and EMI-shielded home for small electronic projects, though users should note that the internal space is very limited due to its small footprint, requiring careful component planning.

Extended Product Information

FAQs

Is the Hammond 1590A waterproof?

It features a lap joint construction that protects against dust and splashing water, but it is not rated for full submersion (IP-rated waterproof).

Can I paint this enclosure?

Yes, but it is recommended to prime the aluminum surface first to ensure proper adhesion of the paint.

What is the wall draft angle and why does it matter?

The 2-degree draft angle refers to the slight slope on the interior walls from the manufacturing process. It matters because it determines exactly how much room you have for your circuit board.

Does this enclosure provide grounding?

Yes, as a metal enclosure, it can be used as part of your grounding scheme, provided you ensure solid electrical contact between your components and the housing.

Are the screws included?

Yes, the 1590A comes with the necessary screws for the lid.

Is it suitable for outdoor use?

It is splash-resistant, but for long-term outdoor exposure, additional sealing or an enclosure with a proper gasket would be required.

Troubleshooting

Lid screws are stripped or difficult to install

Ensure the screw is perfectly perpendicular to the hole and do not over-tighten, as the aluminum threads can wear out with excessive force.

Circuit board is rattling inside

Use nylon standoffs or double-sided mounting tape to secure the circuit board to the base of the enclosure.

Signal interference despite metal housing

Check that the input/output jacks have a good chassis ground connection and that the lid is making firm contact with the base.

Pros and Cons

Pros

  • Extremely durable die-cast aluminum construction
  • Provides effective EMI/RFI shielding
  • Standardized size preferred by DIY pedal builders
  • Easy to drill and modify for jacks and switches
  • Secure lap joint design

Cons

  • Very tight internal clearance
  • Requires professional-grade drilling tools for modifications
  • Not fully waterproof (only splash-resistant)
  • Limited space for large batteries or power supplies

Setup, Compatibility & Care

To ensure the longevity of your enclosure, always use sharp, high-quality drill bits when creating openings for pots or switches to avoid marring the aluminum surface. Because the enclosure is unpainted raw aluminum, it is prone to oxidation over time; if you wish to maintain a bright finish, consider applying a clear coat or powder coating the exterior. When securing the lid, use the provided screws and ensure they are tightened firmly into the factory-tapped holes to maintain the integrity of the lap joint seal. If you are housing high-gain circuitry, ensure that the metal-to-metal contact between the lid and the base is clean to maximize the effectiveness of the EMI shielding.
