Exposed Interior of EC2U

• Empty Housings for Electronic Assemblies
• Designed for 19" Racks
• 2U and 3U Sizes Available

The aluminum enclosures sold here come with blank front and rear panels, as well as two mounting brackets. The mounting brackets allow these enclosures to be stored in standard 19" equipment racks. A mounting board for the inside of each enclosure can be purchased separately below; compatible breadboards are also sold below. Four M3 button head cap screws are included with the enclosure for securing the mounting board or breadboard inside.

To open the enclosure, remove the countersunk screws on both the rear and bottom panels using the included 2 mm hex key, and then slide off the top of the enclosure. Once the enclosure is open, the four M3 mounting holes can be used to secure a mounting board or breadboard.

• 8-32 (M4) and 1/4"-20 (M6) Taps for Mounting
• Four M3 Counterbored Holes for Securing to an Enclosure

The MSBU3038(/M) breadboards are available to fit inside the 19" rack enclosures sold above. These breadboards allow the user to add and remove optomechanical components within the enclosures easily and securely.

The MSBU3038(/M) hole patterns consist of 8-32 (M4 x 0.7) and 1/4"-20 (M6 x 1.0) through-tapped holes, in the same layout as our Mini-Series breadboards. Four counterbored M3 mounting holes are used to secure the breadboard to the mounting studs inside the enclosure. When a breadboard is mounted inside of the EC2U enclosure, the top of the enclosure is 64.25 mm above the top surface of the breadboard; inside the EC3U, the top of the enclosure is 108.8 mm above the top of the breadboard. The bottom of the breadboard is 6 mm above the bottom of the enclosure in both cases.

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.
