A further nine sizes have been added to Hammond Manufacturing’s 1550 family, a range of industry standard sizes small die-cast aluminium enclosures that provide robust mechanical protection and good EMC attenuation levels. he 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 2.36” x 2.17” x 1.02” (60 x 55 x 26mm) to 10.83” x 6.89” x 2.46” (275 x 175 x 63mm); 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.
