• IP degree of protection: Maximum degree of protection acc. to IEC/EN 60529 which can be achieved with this product series. For some product series, for example, a seal may be required and is available as an accessory.
  • IK degree of protection: Maximum impact protection acc. to IEC/EN 62262 which can be achieved with the product series.
  • EMC protection: Basic EMC protection is dependent on the design and can be increased if necessary by means of standard accessories.
  • Railway standard DIN EN 45545: The material in the product series complies with the requirements of railway standard DIN EN 45545 for use with maximum hazard level HL3.
  • Seawater-resistant version: On request, seawater-resistant versions are available with an additional anti-corrosion coating.
  • Wall mounting: The enclosures in this product series can be mounted on a wall without the need for additional processing. Wall brackets (available as accessories) are required for some product series.
  • Hinged catch: The product series is fitted with an integrated hinge, so the lid is captive. For some product series, a hinge (available as an accessory) is required.

Application examples


With its modern design, Bocube Alu sets new design trends in the diecast enclosure sector.
The hinge ensures that the lid is captive. Depending on the mounting, it can be opened to the left or right, as required.
We supply coloured hinges on request; wall brackets are available as an option
The enclosure screws are concealed under design covers and are captive, like the lid screws.
The enclosure lids are available optionally with (2 mm) or without a recessed surface for fitting HMI solutions.
The base has a moulded-on insertion opening for a pressure compensation membrane which can be factory-activated.
A seawater-resistant version (SWB) or a special EMC version is available on request. Additional information can be found in the “Technical Information” chapter.
All enclosure components are metal and captive-connected with the enclosure.
The BA-S variant with a screwed-on cover (both sides) is especially suitable for applications with e.g. a high vibration load.
