Pot Magnet Ø20 mm with Internal Thread
 
The pot magnets contain a neodymium magnet in a purpose-sized steel housing. The housing directs magnetic flux towards the contact surface, providing greater, more controlled holding force for a given size in industrial and workshop applications. Pot magnets can use various magnetic materials, including Alnico, samarium cobalt and ferrite. This series uses neodymium (NdFeB) inserts for their high strength-to-volume ratio. The surface is nickel-coated, typically NiCuNi, to help protect against corrosion and provide a uniform industrial finish. The internal thread allows modular mounting using a screw or stud. Accessories such as hooks, eye bolts and spacers can be attached to suit the application. Nominal diameter: Ø20 mm. Nominal pull-off force under ideal conditions: 14 kg (140 N).
 
The pot magnet performs best on solid steel with a minimal air gap. Allow a safety margin for sideways loads and carry out a trial installation. Typical applications include jigs and assembly aids, temporary attachments, magnetic bases for sensors and stops, signs and labels, and removable holders and brackets. The pot partly protects the insert, but impacts can still damage it. Use moderate tightening force during installation and a washer where necessary. Observe the specified maximum operating temperature. Exceeding it may cause partial or permanent loss of magnetic strength.
 
Warning: not suitable for children. Strong attraction can cause pinching injuries, and impacts may cause chipping. Keep away from electronics and medical devices.
