Hammond Electronics 1550Z die-cast enclosures

The 1550Z die-cast enclosures are thick-wall (3 to 4 mm) IP66-sealed boxes for use in applications where impact protection and environmental sealing are required. The 18 sizes range from 50 x 45 x 30 mm to 223 x 147 x 83 mm, and are supplied in either a natural smooth ‘vibra’ finish or a tough, black polyester powder-coated finish.

Environmental sealing is achieved through a combination of tongue-and-groove construction and a pre-formed one-piece silicone rubber gasket. To ensure the integrity of the seal, the fixing screws are outside the gasket area. Depending on the size, the lid is secured with two, four or six stainless steel machine screws going into factory-tapped holes to aid repeated opening and closing; in six selected sizes with thicker lids, captive screws are used as an alternative.

The bases have raised ‘lands’ to facilitate component mounting; interior space is maximised with smooth walls and a shallow draught angle. To securely attach the enclosures to flat surfaces, through-box blind holes are provided outside the sealed area.
