Thick-walled, waterproof electronic instrument enclosure made of aluminum die-cast. The robust aluminum die-cast alloy is hard yet easy to machine. Two-part tongue-and-groove construction protects against dust and water ingress. The stable, spot-welded bottom flange allows for easy mounting. The textured black version is coated with durable polyester powder, providing a lasting finish even after machining. The finish is applied both outside and inside the enclosure. The gasket is made of pre-formed, one-piece silicone rubber and can be easily inserted into the lid groove. The gasket is suitable for a temperature range of -40 °C to +150 °C. No internal ribs for easy installation of connectors without interference or additional milling. Special feature: with flange, waterproof.
