Magnetic Field Sensors - Contactless and reliable detection Today’s pneumatic cylinders are compact, reliable, and cost-effective prime movers for automated equipment. Unfortunately, they are often provided with unreliable reed or Hall Effect switches that fail well before the service life of the cylinder itself is expended. magnetic field cylinder sensors are based on non-contact, solid-state [...]
Bonded NdFeB Magnets, Bonded Neo Magnets This isotropic resin bonded Neodymium-Iron-Boron material offers a high energy product (3-13 MGOe) between Ferrite and Sintered NdFeB. Application's include sensors and precision motors because it can be produced in complex shapes and magnetisation patterns.Capable of operating up to 120ºC, these magnets may be machined provided that adequate coolant [...]

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. • [...]
