IP54 means the enclosure is protected against dust ingress and splashing water, but it is not waterproof and should not be submerged.
Yes, the natural diecast finish takes paint well. It is recommended to use a primer compatible with metal surfaces for the best adhesion.
Yes, its diecast alloy construction provides effective EMI/RFI shielding, which is beneficial for reducing noise in sensitive radio frequency projects.
The enclosure is made from a high-quality, durable diecast alloy.
Yes, the unit comes with M3.5 x 12 countersunk screws for securing the lid.
Absolutely. The low draft angle of the sidewalls makes this case well-suited for P.C. board installation.
Check the lap joint for debris or metal burrs from machining; ensure no internal components are physically pushing against the underside of the lid.
Use a high-speed steel (HSS) drill bit and apply light cutting oil; maintain a steady, slow feed rate to avoid overheating the alloy.
Do not overtighten the M3.5 screws; align the lid perfectly before inserting the screws to ensure they engage the threads straight.
To prepare your enclosure for use, determine your component layout first to ensure everything fits within the 52.5 x 38 x 31mm cavity. Use a drill press to create holes for switches or jacks, starting with a small pilot hole to prevent the metal from wandering. When mounting your PCB, use the internal walls, as the low draft angle ensures a stable fit. To maintain the enclosure, ensure the lap joint surfaces are free of debris before tightening the M3.5 screws, as dirt can prevent a proper IP54 seal. While the natural finish is durable, you may choose to clear-coat or paint the exterior to prevent long-term oxidation in humid environments.
