Magnetic Bases

Product catalog summary

Overview: The document provides a technical reference for various magnetic bases used in opto-mechanical setups, particularly in laboratories with ferromagnetic work surfaces. These bases are designed to facilitate quick and secure positioning of optical components.

Magnetic Bases: Magnetic bases are essential for reducing setup time by allowing free positioning and instant clamping of optical components. They are ideal for use with Newport optical tables and breadboards.

Low-Profile, Heavy Duty Bases: Models 150 and 200 are highlighted for their high holding force, low profile, and stable magnetic circuit design. They feature a continuously variable holding force with easy adjustments and a non-magnetic mounting surface. An inset adjustment screw allows for convenient force variation.

Kinematic Magnetic Base: Model 110 is a space-efficient base with a kinematic interface and tapped mounting holes. It allows for repeatable precision in component positioning and can be attached to tables on its side. The kinematic top plate ensures high position repeatability and secure clamping of loads.

Utility Magnetic Base Plate: The MB-1 Magnetic Base Plate is designed for quick positioning of small components using a single bolt. It is suitable for VPH or MPH Series Post Holders.

Compact and Standard Magnetic Bases: The MB-3 features an aluminum mounting plate with multiple tapped holes, providing decoupling from the magnetic field. The MB-2 offers a single tapped hole for mounting post holders.

Specifications: The document includes detailed specifications for each model, including holding forces and thread dimensions. Models 150 and 200 offer holding forces of 300 lb (1334 N) and 200 lb (890 N) respectively, while Model 110 and MB-3 provide 90 lb (400 N).

Ordering Information: The document provides model numbers and descriptions for ordering, emphasizing availability on select items through Newport's website.

They are the ideal accessories for all laboratories with ferromagnetic work surfaces such as Newport optical tables and breadboards. Low-Profile, Heavy Duty Bases Newport’s Models 150 and 200 are premier magnetic bases that combine all the most desirable features including a high holding force that does not degrade with time, a low profile, generous mounting provisions, continuously variable holding force with easy-toreach adjustments and a non-magnetic mounting surface. These bases incorporate an exclusive, stable magnetic circuit design, which linearly translates the magnetic elements. Unlike most designs that are unstable between on and off, the holding force of these bases may be continuously varied. An inset adjustment screw, which varies the holding force, is conveniently accessible from either side of the base. 150 and 200 Hex key included Kinematic Magnetic Base 110 (M-110) Newport’s unique Model 110 Kinematic Magnetic Base is a space-efficient base that adds an inset kinematic interface to a generous array of tapped mounting holes. Components may be attached directly to the base, or the unique kinematic top plate lets you remove components and replace them with repeatable precision. Model 110 may also be attached to tables on its side. The kinematic top plate is equipped with spring-steel clamping hooks that hold the kinematic plates together. Alternatively, two bolts may be used to clamp the plates together. This provides secure clampdown of cantilevered or rod-mounted loads. The locking bolts are accessible even when a standard 1.5 in. (38 mm) diameter rod is attached. Model 110’s kinematic top plate (included) provides extremely high position repeatability. • Ideal for quick setups • On/Off switchable versions with strong holding forces • Available with kinematic top plate for repeatable positioning • Non-magnetic mounting surfaces with versatile hole patterns Utility Magnetic Base Plate MB-1 Magnetic Base Plate quickly positions small components mounted via a single 1/4-20 (M6) bolt, such as VPH or MPH Series Post Holders.
