A Fifth Mounting Hole in the Middle of the Breadboard Increases Rigidity and Reduces Stress When Mounting Heavy Loads
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 of 1/4"-20 (M6 × 1.0) tapped holes (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 the image to the far right, 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 photo to the right). 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.
For vacuum applications, we recommend using our selection of Unanodized Breadboards.
