Eclipse Magnetics Alnico 5 Cylindrical Bar Magnets are compact permanent magnets designed for sensing, switching, educational and low-force positioning applications.
Supplied as a pack of 2, these cylindrical bar magnets are magnetised along the long axis and are available in 4mm, 5mm and 6mm diameters, with each magnet measuring 10mm in length.
Manufactured from Alnico 5 magnetic alloy, the range is suitable for applications requiring stable magnetic performance at elevated temperatures, with operation up to approximately +550°C.
Each model provides a typical surface field of around 1200 Gauss at the pole face, making the magnets suitable for applications such as reed switch activation, Hall-effect sensing, proximity detection and educational demonstrations.
The E808, E809 and E810 models are supplied with a natural uncoated finish and are intended for sensing, locating and light positioning rather than heavy-duty magnetic clamping.
For additional high-temperature permanent magnet options, explore our wider range of Alnico magnets.
