Magnet Rods Ø 4 Mm, Height 25 mm

This 4 mm diameter, 25 mm height neodymium rod magnet offers exceptional magnetic force in a compact size. Using N42 grade NdFeB material and a Ni-Cu-Ni coating, we deliver a durable magnet with strong performance. It's ideal where tight spaces demand reliable magnetic pull - like sensors, assemblies, tools, or small mechanisms.

Each rod supports a weight up to 670 g when placed flush against mild steel - impressive given its small footprint. Thanks to its resistance to demagnetization, it also works well for damping, magnetic coupling, or small actuator designs.

• Compact but powerful - fits in tight assemblies while delivering useful pull.
• Reliable & stable - holds magnetism well over time, reducing performance drift.
• Customizable options - we can produce other lengths, grades, coatings on request.
• Batch consistency - we maintain strict QC across production runs.
• Bulk supply capability - we handle both prototype orders and large volume runs.

• Miniature actuators and motors
• Sensor assemblies and probes
• Magnetic couplings or dampers
• Tool holders, fixtures, and jigs
• Precision mechanisms in electronics, robotics, medical devices
