Thorlabs offers enclosure options for customers interested in assembling their own 19" rack-mounted electronic devices. Our enclosures are available with one of two rack unit (U) heights: 2U or 3U. The front and rear panels of the enclosure are blank; input and output ports can be added by the user depending on the application.

A mounting board or breadboard (sold separately below) can be secured inside either the EC2U or EC3U enclosures. The ECUMB mounting board provides a surface with 18 mm x 5 mm slots for assembling electronic components, such as PCBs, development boards, and power supplies. Alternatively, the MSBU3038(/M) breadboard features a high-density hole pattern of 8-32 (M4) and 1/4"-20 (M6) tapped holes to allow optomechanical components to be mounted inside the enclosure. Both the mounting board and breadboard are secured using the 2 mm hex key and four M3 button head cap screws included with the enclosure.

The EC2US and EC3US mounting strips may be used to replace the mounting brackets and reduce the profile of the EC2U and EC3U, respectively. The ECUF rubber feet may be attached to either enclosure for benchtop usage.

For housings that hold smaller, custom electronic circuits, such as electrical filters, voltage dividers, or impedance matchers, see our compact customizable electronics housings. For housings that are not designed to be mounted in a 19" rack, please view our benchtop customizable electronic housings.

Dear sir, dear madame, When looking at the page of the smaller benchtop enclosures, I see that it is possible to design where holes are cut into the enclosure. It is even possible to print your custom text on it. For the 19" racks, I don't see this option. Is it possible to process in the same way the 19" racks? For my applications, the benchtop racks are too small. If not, how are we supposed to make holes in the aluminium housing (drilling is possible for small ones, but larger holes, like for power supply or fan are not easily drilled in a nice way - at least not by me... Thanks for your advice. Peter.

EC2U Enclosure with ECUF Rubber Feet and EC2US Plates Installed
  • ECUF Rubber Feet for Benchtop Usage
  • EC2U and EC3U Plates to Replace Mounting Brackets

Accessories are available to convert the EC2U and EC3U rack enclosures into enclosures that are more suited for benchtop use. The EC2US and EC3US plates can replace the mounting brackets of the EC2U and EC3U respectively and reduce their profile. To install them, remove the countersunk screws on the rear and bottom panels of the EC2U or EC3U to remove the top of the enclosure. Remove the M3 screws that secure the mounting brackets to the enclosure chassis and use the M3 screws to secure the EC2U or EC3U to the chassis.

The ECUF rubber feet can be installed on the bottom of the EC2U or EC3U enclosures. The included M4-14 cap screws and 3 mm hex key fasten the rubber feet to the M4 screw holes located on the bottom of the enclosure.
