Demagnetization prior to parts cleaning MM DN + SE

Constant-Field-Technology ®

Perfect demagnetization for perfect cleanliness Maurer-Degaussing®-Technology Manufacturers of cleaning machines guarantee achieving the specified residual dirt limits of ferromagnetic parts, only up to a defined residual magnetism level. This requires a powerful and stable demagnetizing process. Especially for this OEM-segment, Maurer Magnetic AG offers the new MM DN + SE demagnetizer. The power is designed to meet current requirements defined by the fine- and ultra-fine cleaning machine manufacturers (residual magnetism < 2A/cm at a Hall effect zone distance of ~2mm to the surface of the part).

Features • C overing standard cleaning baskets by a large diver sity of coil dimensions.

Demagnetization prior to industrial cleaning processes Residual magnetism in a part causes attractive forces on ferromagnetic dirt particles. The particles stick on the surface of the part. This magnetic forces increase near to the surface, therefore even modern cleaning systems can‘t remove the dirt particles completely from the part. A safe process can only be reached by a proper demagnetization of the parts prior to the cleaning system. Suitable for bulk material or oriented parts

Demagnetizing with MM DN + SE offers you: • N o sticking of ferromagnetical particles • C leanliness after the cleaning process • L ow energy consumption do to pulse demagnetization

Also usable for larger parts with several inches of wall thickness

Handling • S imple integration of the demagnetizer into the auto mation system can be realized by the manufacturer of the cleaning system. • S maller systems are directly integrated on the infeed conveyor

Horizontal field direction of the coils: (Usually 2 coils)

Vertical field direction of the coils: (Usually 1 coil, 2 coils possible if necessary)

Demagnetizing coil SE The demagnetization coils of the SE product line are specially designed for the requirements of modern cleaning systems. If nesessary, a second coil can be used. This configuration with 2 coils is called Helmholtz-Coil. With the Helmholtz-configuration the system generates enough field volume to demagnetize even large washing baskets.

Industrial Duty Demagnetizer MM DN + VE

Field Multiplicator Technologyâ&#x20AC;&#x2030;ÂŽ

Removing residual magnetism effectively and efficiently Modern industrial manufacturing processes impose limits for remanent magnetism on components at 2 A/cm. For example, it is not possible for parts to become sufficiently clean after being washed, or for welding processes to run smoothly, at a residual magnetism exceeding these limits. The MM DN + VE degausser is the perfect choice to efficiently and productively demagnetize parts in your manufacturing process. Depending on the design, the MM DN + VE degausser creates a degaussing field of 50 up to 180 kA/m. This makes it possible to demagnetize bulk parts in carriers, transport containers, or complex individual parts, with a pulse lasting only a few seconds – and at a quality level never before reached. The brief demagnetization pulse, the precise dimensioning of the active opening, and the fine tuning of the field strength make sure that the demagnetization process is highly effective. The MM DN + VE degausser is ready to be integrated into highly automated manufacturing processes in an industrial environment. Its operation is simple and intuitive. Its wide performance range makes this degausser the trendsetting demagnetizer for production lines of the future.

State-of-the-Art technology to meet future requirements

Maurer-Degaussing®-Technology

The high-performance demagnetizers are the most powerful products in Maurer Magnetic’s demagnetizer line. The patented Maurer Degaussing Technology has been perfectly implemented into these products, and demagnetizes any parts. Magnetically hard materials, interior components of shielded parts, or large volumes of bulk materials are completely demagnetized by the magnetic field, which reaches field strengths of up to 400 kA/m in powerful coils. Fully flexible cable coils even ensure the demagnetization of large parts that weigh up to 50 tons.

The fully-automatic demagnetization process demagnetizes the material within a few seconds with a powerful degaussing field pulse. The unit’s operation can be manual or integrated into an automated production process.

Modular configuration The demagnetization system is modularly structured into the MM DM power modules, the MM HLE coil modules or other special coils. This means all demagnetizers can be implemented extremely flexibly. Thanks to the fact that the coil is separate from the MM DM power module, operators do not suffer undue exposure to the electromagnetic field. Various coil modules can be operated without adjustment using a mobile MM DM power module.

Demagnetization with CT-UDM universal coils

Demagnetization with the MM HLE high-performance coils

Different kinds of parts can be demagnetized with CT-UDM coils. The parts are placed inside the coil and are demagnetized within a few seconds. Universal coils are generally used in addition to other coils, such as cable coils or the MM HLE coil.

The MM HLE high-performance coils are generally used in industrial environments and automated production lines. The active opening and the field strength are tailor made. Typical applications are: Demagnetization • at the beginning of washing processes • in preparation for welding work • for compliance with technical requirements

Demagnetization with cable coils

MM DM power modules

Large parts are demagnetized using flexible cables. The cables must be wrapped around the part to be demagnetized. The degaussing pulse removes the magnetism from the part.

Demagnetization with the MM HLE high-performance coil integrated into a protective housing We recommend using the protective housing in manual working environments for the MM HLE high-performance coil. The housing protects operators and other personnel from unwanted exposure to the electromagnetic field. The active opening of the coil is available horizontally or vertically on customer’s request.

The demagnetization program defines the frequency and the form of the degaussing pulse.

The offset settings superimpose a static field on the demagnetization process, e.g. to compensate the earth’s magnetic field. Offset works only with cable and universal coils.

During continuous demagnetization, the degaussing field stays at constant amplitude. This is typically used to demagnetize very long parts.

With the MM DM-PC, four demagnetization programs can be selected through the 15-PIN D-Sub interface; or an unlimited number manually.

Coil modules The strong magnetic field required to demagnetize the object is created by the coil modules. Our wide range of coil modules allows us to offer a standardized and efficient solution in various applications. High-performance coil module

Up to date specifications for demagnetized components require a residual magnetism of 4A/cm or less. The influence of induced geomagnetic fields, misclassifies the measurements. The Zero Gauss Chamber delivers consistent test results due to measurements taken within a chamber that shields the magnetic field of the earth. Therefore the test results can be reproduced at any location, which provides global quality control.
