The Alnico Cylindrical Bar range – Models E808, E809 & E810 – deliver compact yet stable magnetic performance using Alnico 5 material, ideal for sensing, switching and educational applications. These straight cylindrical bars are supplied in pairs, operate reliably at elevated temperatures (up to +550 °C) and provide a typical surface field strength around 1200 Gauss (0.12 T). 

Key Features

  • Alnico 5 magnetic alloy – retains magnetic output at high temperatures up to approximately +550 °C. 
  • Cylindrical bar geometry with magnetisation along the long axis, supplied in pairs for convenience. 
  • Compact diameters of 4 mm, 5 mm and 6 mm with a fixed length of 10 mm, making them suitable for space-constrained applications. 
  • Typical residual surface field of ~1200 Gauss (~0.12 T) at pole faces — sufficient for triggering reed switches and Hall-effect sensors, but not designed for heavy clamping.  
  • Natural (uncoated) finish for E808–E810 models, offering good corrosion resistance and simplified integration.  

Typical Applications

  • Sensor actuation such as reed switches, Hall-effect sensors or proximity detectors.  
  • Educational or laboratory demonstrations of magnetism and field behaviour.  
  • Low-force magnetic locating, holding or positioning of ferrous components in assemblies where temperature stability is required.
