IP 66, Optional: IP 67 aluNORM IP 66 diecast aluminum enclosures are designed to protect electrical and electronic components. The enclosures are available in four different versions with different lid and base combinations. This gives a huge variety of sizes and design options to choose from. Uniquely, aluNORM enclosures are mounted to a wall or machine using the same screw channels as the lid fixings. This means there is more space inside for your assemblies and components. RFI/EMI shielded versions are also available for the AS and AD variants, and some AF and AH variants - see ordering details. Threaded screw bosses in the lid and base enable fast installation of terminal rails, mounting plates etc. Matching cable glands and accessories are also available. We can supply aluNORM enclosures fully customized to your requirements.
