Hammond Electronics 1550Z IP66 sealed box range

Click2Contact

The 1550Z family of die-cast enclosures is a range of thick wall (3 to 4 mm depending on size) IP66 sealed boxes for use in applications where impact protection and environmental sealing are primary requirements.

The 18 industry-standard sizes in the family range from 50 x 45 x 30 mm to 223 x 147 x 83 mm and as standard they are supplied in either natural with a smooth vibra-finish or in a black polyester powder-coated finish.

Environmental sealing is achieved through a combination of a tongue and groove construction and a preformed one-piece silicone rubber gasket. To ensure the integrity of the seal, the fixing screws are outside the gasket area.

Depending on size, the lid is secured with two, four or six stainless steel machine screws going in to 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 PCB or component mounting. Interior space is maximised with smooth walls and a shallow draught angle. For securely attaching the enclosures to a surface if required, through-box blind holes are provided outside the sealed area.
