Features

• Black Anodized Solid Aluminum Construction
• Metric Boards Manufactured & Stocked in Europe
• Counterbores for Mounting Breadboards
• Same Hole Pattern as Our Circular Optical Breadboards
• Standard, High-Density Versions, and Custom Sizes Available

Our Double-Density Breadboards are constructed from a 1/2" (12.7 mm) thick aluminum plate to maintain flatness over the full length and provide a double-density hole pattern 1/4"-20 (M6 × 1.0). See the Hole Patterns tab for information on tap spacing.

The small footprint and slim profile make these breadboards ideal for compact areas. Since the holes are threaded completely through these base plates, components can be mounted on both sides at once. Standoff posts allow the breadboards to be mounted above the surface of an optical tabletop (or breadboard), as shown in Figure 1.2, for access to components on both sides.

Each breadboard features four or five mounting holes, offset from the array of 1/4"-20 (M6) threaded holes, which are counterbored to create an uninterrupted surface for any intended application. The four standard mounting holes are located at each corner of the breadboard, inset 1" from each edge (25 mm on metric). All breadboards except the MB12D, MB1530/M, and MB3030D/M include a fifth counterbored mounting hole at the center of each board. Using the center mounting hole increases the mounting options available, reduces stress at the corner mounting holes, and increases rigidity when heavy loads are placed on the boards (see Figure 1.1). The mounting holes may be used to attach the breadboards to optical tables, other breadboards, mounting posts, brackets, or a variety of other surfaces or mounts.

One imperial and one metric breadboard below are designed for use with the EC2530C enclosure. They are thinner than the other breadboards on this page, and the mounting counterbores are positioned to allow the breadboards to be mounted within the enclosure. See our benchtop enclosures for custom electronics for details.

We also offer Mini-Series breadboards with high-density hole patterns. For vacuum applications, we recommend using our selection of unanodized breadboards.
