REED SWITCH MAGNETS Reed Switches are amongst the simplest of all the magnetic field detection devices. It consists of two thin ferromagnetic plates (usually nickel-iron or nickel-cobalt) called reeds within a glass ampoule (casing) which overlap each other except for a small gap between them so they are not quite touching. Reed Switch Magnets [...]
SENSOR MAGNET SELECTION Magnetic field profiles example Magnets, electromagnets and solenoids could all be used to trigger magnetic sensors such as Reed Switches and Hall Effect devices. The choice of magnet is determined by the actual application and the environment of the application. Temperature, distance and location of the magnet, presence of other [...]
HSMAG is a sensor magnet supplier. HangSeng Magnetech designs, produces and supplies magnets and magnetic assembly solutions for the Sensors Industry. Magnets for Sensor We can design magnets to provide specific field strengths at a required position relative to the magnet. We can design magnets to trigger Hall Effect devices at different locations compared [...]
Electric Power Steering System Sensors and Power ICs Power Steering Systems Electronic Power Steering (EPS) systems are becoming prevalent in automotive systems and are quickly replacing hydraulic assist power steering. The move to EPS systems is driven by the necessity for improving overall fuel efficiency and reducing system cost in automobiles. EPS systems [...]
HSMAG products support customers with diverse solutions for rotary measurement, both incremental and absolute. Rotary solutions are used for continuous or discrete positioning, motion control, such as commutation, and many other solutions. Rotary Magnetic Scale Rotary measurements requires two components: Rotary sensing heads Rotary scales HSMAG develops and produces both absolute and incremental [...]
Magnetic measurement is using a scale where the patterns are defined with magnetic north and south poles. The different types of sensor technology - Hall sensors or magneto resistive sensors - are used to read the magnetic pattern and convert them to a electric signal that is used for a motion controller or other electronic [...]
