Thorlabs' Mini-Series breadboards, designed for setups where space is a premium, offer increased tapped hole density with 1/2" (12.5 mm) spacing. These high-density breadboards are offered with either 4-40 (M3) tapped holes or both 8-32 (M4) and 1/4"-20 (M6) tapped holes.

Our Mini-Series line consists of components that are compatible with 4-40 (M3) or 8-32 (M4) threads. The 4-40 (M3) taps in the MS12B(/M) breadboard make it compatible with smaller 4-40 (M3) Mini-Series components, such as our Ø6 mm posts. Our other breadboards are compatible with 8-32 (M4) Mini-Series components, such as our Ø12 mm pedestal posts and MSL post holders, and also include 1/4"-20 (M6) taps for integrating larger optomechanical components, such as our Ø1/2”, Ø1”, and Ø1.5” post assemblies.

Each breadboard features two, four, or five counterbored mounting holes, depending on the size of the board, enabling these breadboards to be mounted onto our standard breadboards, mounting feet, or post assemblies. For breadboards that have a fifth counterbored hole, it is located at the center of the breadboard to reduce stress at the four corners and to increase system rigidity when mounted. Refer to the tables below for more specifications.

Three imperial and three metric breadboards with both 8-32 (M4) and 1/4"-20 (M6) tapped holes, featured below, are designed for use with customizable electronics enclosures. The mounting counterbores are positioned to allow the breadboards to be mounted within the enclosure. See our benchtop enclosures for custom electronics or our 19" rack enclosures for electronics for details.

Custom Breadboards
We offer a service for custom breadboard orders, with options that include hole pattern and spacing, size, thickness, and anodizing. For a quote, please use our contact Tech Support.

Breadboards for Electronics Enclosures, 8-32 (M4) and 1/4"-20 (M6) Taps

The MSB1823(/M) and MSBU1823(/M) breadboards are designed to fit inside the EC2030A(R) or EC2030B(R) benchtop enclosures for custom electronics, and the MSBU3038(/M) breadboard is designed to fit inside the EC2U and EC3U 19" rack enclosures for custom electronics.The MSB1823(/M) and MSBU1823(/M) have a thickness of 7.0 mm while the MSBU3038(/M) has a thickness of 0.37" (9.5 mm). In addition, these breadboards have four M3 counterbored mounting holes for compatibility with the enclosure, rather than 1/4" (M6) counterbored holes.
