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 the ingress of dust and water. The stable, spot-welded bottom flange allows for easy mounting. The unpainted version features a vibration finish for a smooth surface without sharp edges. The seal is made of pre-formed, one-piece silicone rubber and can be easily inserted into the lid groove. The seal is suitable for a temperature range of -40 °C to +150 °C. There are no internal ribs for easy installation of connectors without interference or additional milling. Special feature: with flange, waterproof.
