Sensor Permanent magnets, magnetic sensor assemblies, magnetic sensors 1, Help us designs of  Sensor Permanent magnets We do not make sensors; we make the magnetic assemblies that enable these devices to operate effectively. In order to make a perfect magnet assembly, we would need to know the following: 1. What type of magnetic sensors are you [...]

  • Magnetic Sensors

Magnetic Sensors

Magnetic sensors indirectly measure properties such as direction, position, rotation, angle and current by detecting the magnetic field and its changes. Compared to other direct methods, such as optical or mechanical sensor, most magnetic sensors require some signal processing to get the property of interest. They provide reliable data without physical contact even in adverse [...]

Permanent Magnets Markets and Devices / Applications

Permanent Magnets Markets and Devices / Applications Devices • Electromechanical machines and devices e.g. motors, generators, actuators • Acoustic transducers e.g. speakers,  earphones, ringers • Mechanical force and torque devices e.g.  holding, lifting, clutches • Microwave and ion beam control e.g.  TWT’s, particle accelerators • Conversion of external stimuli to electrical signal e.g. sensors • DC field generation e.g. MRI Markets and Industries • Automotive and transportation • Industrial and commercial • Consumer products • Military and aerospace • Medical Permanent Magnets Markets and Devices Applications Sensors/Encoders Hall Effect Encoder for end of shaft applications.  Available as either absolute or incremental encoders they can provide digital position, analog position, and quadrature speed outputs. Capable of rotational speeds over 20k RPM. Hall IC used for this application uses a diametrically magnetized magnet. Hall Effect through‐shaft encoder.  Requires use of Hall IC capable of off‐axis sensing using multipole bonded magnet. Low cost, speed or position sensors typically seen in automotive applications – Cam position, crank position, engine speed, ABS.  This type  of sensor can be designed for either face or lateral sensing applications and may, in addition to the Hall IC, incorporate a magnet if sensing a metal target or a pole piece if sensing an encoder multipole magnet. What is the best permanent magnet material and process? •It depends; on the weight/space limitations, application operating conditions, operating parameters of the magnetic circuit, annual quantity, device assembly mechanization etc. • Despite have lower flux output bonded magnets can offer advantages over sintered magnets for many applications. • Despite lack of breakthrough in new materials over the last 30 years there are several promising developments in bonded magnets on the horizon. • [...]
