Magnetic Product Description:

This popular rare earth cylinder has a diameter of 3mm and a height of 5mm. It is an N45 grade rare earth magnet. It has a magnetic flux reading of 6556 Gauss and a pull force of 0.345kg.  It is identified by the AMF magnet part number C-D3H5-N45.

Uses for our rare earth cylinder magnets:

Neodymium cylinder magnets typically produce a narrow, deep field that is emitted through the flat surface at each end. This characteristic is put to use in various high-tech applications where they are valued for their strength and relatively small size. Switch mechanisms, safety systems and alarms are all magnetic products that are activated with a magnet of the appropriate size, strength and field depth. Permanent magnets operate independently from outside power sources and, unlike mechanical switches, have virtually no moving parts that can fail over time or with extensive use. Small Neodymium cylinders in proximity to steel or electromagnetic fields can be used to open or close electrical circuits. Reed switch equipment often has a vacuum-sealed switch that is never exposed to corrosive atmospheres and this greatly improves their long term reliability. Permanent magnets can be used to penetrate non-magnetic surfaces to operate the switch remotely. This contactless method of activation is used extensively throughout the motor vehicle industry to operate warning and safety systems. Appliance and computer on/off switches are often operated with magnetically operated reed switches.
