Hammond Electronics’ 1550 family is a range of industry standard sizes small die-cast aluminium enclosures that provide robust mechanical protection and good EMC attenuation levels. The tapped holes and machine screws used to secure the lid make them particularly suitable for use where interior access will be required on a regular basis in a wide variety of applications. Available with a natural or black epoxy powder coated finish, the units are supplied in two versions, standard and watertight. The sizes range from 60 x 55 x 26mm to 275 x 175 x 67mm; the standard units are sealed to IP54. The 1550W watertight versions are supplied with a separate compressible self-adhesive gasket, which, when fitted between the lid and the base, provides dust and water sealing to IP66, enabling them to be used in both benign and hostile environments.
The thin wall aluminium enclosures have high impact strength but are also easily drilled and punched to accept cables, switches and indicators as required. All units can be supplied factory modified with machining and silk screening to the user’s specification; AutoCAD and PDF dimensioned drawings can be downloaded from http://www.hammondmfg.com/1550.htm
The 1550Z family is a range of thick wall (3 to 4mm 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 30mm to 223 x 147 x 83mm, and as standard they are supplied in either natural with a smooth vibra-finish or in a tough black polyester powder coated finish. Economically priced, the units offer outstanding value for money, achieved by multi-impression tools and automated machining and finishing during manufacture.
Environmental sealing is achieved through a combination of a 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 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.
