Robust electronic instrument enclosure made of aluminum die-cast alloy (tough yet easy to machine). Coated with a smooth, glossy polyester powder coating for a durable surface, even after machining. The overlapping design provides protection against dust ingress and splashes. It also ensures improved EMI/RFI shielding. Complies with IP54. The sealing kit meets IP65 standards. The IP65 protection class also requires waterproof screws.
