Product catalog summary
Overview
The document describes the yoke type surface demagnetizer MM JE, developed by Maurer Magnetic AG, featuring the Automatic Field Decline Technology (AFDT) and Constant-Field-Technology (CFT®). These technologies ensure a consistent magnetic field and gradual field decline upon switching off, preventing remagnetization of parts.

Specifications
  • Models: MM JE165, MM JE266, MM JE300
  • Dimensions: Vary by model (e.g., MM JE165: 250 x 165 x 75 mm)
  • Working Width: Ranges from 165 mm to 300 mm
  • Maximum Field: 50 kA/m peak
  • Operating Temperature: 0°–40°C
  • Power Consumption: 28 W to 41 W
  • Power Supply: 200-240 VAC/50 Hz/3A or 110-120 VAC/60 Hz/3A
  • Weight: 9 kg to 19 kg
  • Protection Class: IP 42

Key Features
  • AFDT ensures no magnetization of parts when switching off.
  • Parts can be demagnetized without moving them over the surface.
  • No outflow zone needed after passing the operating area.
  • Secure manual operation with no remagnetization before part removal.

Operation and Best Practices
  • Manual operation involves sliding parts slowly over the demagnetizer surface.
  • For best results, reverse parts and demagnetize both sides.
  • Parts thicker than 10 mm should be demagnetized from all sides.
  • Consider using two yoke demagnetizers for optimal results.

Applications
The demagnetizers are suitable for removing magnetism from ferromagnetic parts up to a penetration depth of about 10 mm, making them ideal for tools or flat parts.

Integration and Automation
All JE series demagnetizers have an interface for integration into automated processes.

MAURER Classic + Demagnetizers with automatic field decline function Yoke demagnetizers MM JE165 / 266 / 300 are surface type demagnetizers developed by Maurer Magnetic AG. They can be used either manually or integrated in automated processes. They are powered by mains frequency. The demagnetizer MM JE produces a stray field over the middle of the top panel. The operating area of the stray field of a yoke demagnetizer is more volumious as for example the field produced by a plate demagnetizer. Magnetism of ferromagnetic parts can be removed up to a penetration depth of about 10 mm. Therefore...

Yoke type surface demagnetizer MM JE-3

Operation and range of application In manual operation slide the part you want to demagnetize directly with a slow and continuous movement over the surface of the demagnetizer. The alternating field reaches it‘s maximum at the center of the plate. Alternatively the parts can be demagnetized by using the field decline function. Put the part in the middle of the top panel an press the pulse button. The alternating decreasing field will demagnetize the part automatically. How to get the best results 1. ove the part slowly and continuously from point M I to O over the surface. 2. everse the part...
