EC1U Enclosure Shown Disassembled


  • Red Aluminum Housings
  • Easy Assembly and Disassembly
  • Enclosures are Stackable with EC1UA Adapters

The EC1U enclosure design has been optimized for simple assembly, disassembly, and integration. The enclosure consists of three pieces: a bottom/front piece with four interior M3 blind standoffs and an M4 grounding screw, a flanged top with cutouts for mounting to an imperial or metric breadboard or optical table, and a bezel that secures both pieces together using two screws. The front and rear panels of the enclosure are blank; input and output ports can be added by the user depending on the application.

Enclosures can be easily stacked on top of one another using the EC1UA mounting adapters, sold below. Alternatively, the ends of Ø1/2" or Ø12.7 mm optical posts can be used to secure the enclosure flanges by positioning the post screws in the flange slots. This clamps each flange between either the optical table and the bottom of a post, or between the endface of two posts.

Thorlabs offers the capability to make custom enclosures using laser cutting, riveting, UV printing, and more. Contact Tech Support for more information on building a custom flanged benchtop enclosure.

EC1U Mounted to Table
  • Empty Housings for Electronic Assemblies
  • Simplified Benchtop Design

The EC1U benchtop enclosure is designed for ease of assembly, modification, and installation. The empty enclosure is sold with with blank front and rear panels. The external dimensions of the enclosure are 139.0 mm x 106.7 mm x 46.5 mm, excluding the flanges and feet. The maximum internal dimensions are 133.0 mm x 102.6 mm x 42.5 mm; this does not account for assembly features such as interlocking tabs or standoffs. Detailed dimensions of the enclosure are available by clicking on the red Docs icons () below.

Two M3 screws, one on each side, secure the front bezel, which locks the inside and outside pieces together. Two extra screws are provided, as well as a 2 mm hex key for convenience. To open the enclosure, loosen the two screws with a 2 mm (5/64") hex key and then pull the bezel upwards. This frees the bottom piece to be pulled away from the top of the housing, allowing the entire housing to be separated.

Four padded feet are included to provide support when the enclosure is sitting flat on a table. Additionally, the enclosure can be mounted to imperial or metric optical tables using the cutouts in the flanges. See the images to the right.
