For a famous magnet company in the pneumatic field we have realized 1000. 000 injection ferrite rings and 100.000 neodymium rings for pneumatic cylinder magnetic sensor.
The final customer’s need was to improve sensor’s reading precision reducing dimensions.
His first solution was a plasto-ferrite ring, axially magnetized. The low properties of this magnetic material forced the use of a lumbering magnet, beyond the necessity of keeping the ring very close to the sensor for a better reading. Industry Sensors Pneumatic Cylinder Magnets
Our work, instead, focused on the realization of sintered neodymium magnet ring, axially magnetized and coated with epoxy resin.
The ring magnetic performances, definitely higher than previous solution, allowed to reduce sensor’s dimension, offering a more precise reading. Consequently, the distance between magnet and sensor increased. The axial magnetization of neodymium ring has been realized more perpendicular comparing with the one of plasto-ferrite magnet. In the end, epoxy coating has garanted a longer life of pneumatic cylinder. Standard Air Cylinder Magnet
End customer has finally obtained a better sensor’s precision, putting on the market an evolved system, with reduced sizes. Pneumatic Cylinder Sensor Magnet
MPCO is able to projects and produce customized magnets, to satisfy every customer needs.
The line of magnets for sensors is designed to meet the requirements of non-inductive sensor manufacturers that need position, level, adjustment and distance detection. Pneumatic Cylinder NdFeB Magnet Ring Epoxy Coated
Magnets for sensors of equal dimensions offer constant switching through time at greater distances from the sensor. Aluminium or non-ferrous metallic walls do not compromise switching. Furthermore, they are unaffected by vibrations and can be installed sideways or at the front. The magnet can be embossed on the wall or recessed without compromising its correct function.
