Cylinder Neodymium Magnet

PRODUCT DESCRIPTION


Cylinder Neodymium Magnet Introduction


Cylindrical neodymium magnets are long, circular magnets that extend beyond their diameter and are typically used in recessed boreholes for clamping applications that require a large magnetic field. We also offer ring magnets.


Cylinder Neodymium Magnet Size


---Normal Size Range: D (Diameter): 1~180mm, T (Thickness): 0.4~150mm

---Maximum Size: D180 x T60mm, D80 x T150mm

---Minimum Size: D1 x T0.4mm

---Orientation Direction Size: Lower than 80mm

---Tolerance: Generally +/-0.1mm, Particularly +/-0.03mm


Neodymium Cylinder Magnets Machining Method


Generally, the small axially oriented cylinder (<D10mm) and almost all diametrically oriented cylinder is EDM cut from the big block and then grinded and sliced. The big axially oriented cylinder(>D10mm) can be pressed to shape and then grinded and sliced. But sometimes the big axially oriented cylinder should be core-drilled or EDM cut from a block, so as to ensure the magnetic properties especially for high end grades or shorten the lead time. Prior to coating, the small cylinder needs vibration tumbling and the big cylinder needs manual chamfering.


Application of Magnet


Cylindrical Neodymium Magnet for Magnetic Sensors:

Cylinder Neodymium magnets are used to trigger magnetic sensors in a variety of applications. There are two main styles of magnetic sensors – the reed switch and the Hall Effect. Several parameters must be taken into consideration in order to select the proper magnets:

---Sensor style (Hall Effect or Reed)

---Trigger threshold (Hysteresis)

---Mechanical movement (Magnet relative to the sensor)

---Environmental conditions

---Dimensional requirements

---The proximity of flux biasing alloy

Magnetic sensors are widely used in a variety of consumer products such as printers, scanners, cameras, and flat panels. One of the fastest-growing applications of magnetic sensors is mobile navigation – the electronic compass is a must-have feature in mobile devices such as smartphones and tablets. Magnetic field sensors are also commonly found in gaming consoles and in many products with smart features.
