Yes. Special dimensions can be customized, with a minimum size of 100×80×50 mm. Customization does not affect the protection performance, as the sealing structure continues to use the polyurethane foamed gasket. The lid and body are re-fitted precisely to maintain the IP56 protection level and ensure compliance with certification standards.
