The device features - Ferromagnetic actuated reed switch, detects ferrous metal through nonferrous metal, one piece housing. It doesn't matter which end of the magnet approaches first: the contacts still polarize in opposite ways and attract one another. A reed switch consists of a pair of ferromagnetic blades hermetically sealed in a dry, inert-gas atmosphere at opposite ends of a glass capsule. Each reed switch has a number of ‘active’ regions surrounding it, sometimes referred to as lobes, the size of which varies depending on the sensitivity of the switch. The sensitivity of a reed switch is rated based on the magnetomotive force measured in the ampere-turns (AT) required to pull in or release the contact points. Typically the magnetic field is generated by a permanent magnet, but a current carrying coil of wire may also be used. 5. Magnetic transducers are widely used in modern industry and electronics to sense the magnetic field strength to measure current, position, motion, direction, and other physical parameters. Rp8.500. 99 $9.99 $9.99. Magnetoresistive effect: As the name 'magnetoresistive' says, the resistance of a special material is changed by a magnetic field. This is a priori challenging for electroplated wires and compatible only with very thin insulating layers, for the sake of the electroplating of the second electrode. Access control locks on doors have come a long way in the past 30 years or so. Balluff's magnetic field sensors will work with magnetic strengths as low as 15 Gauss unlike the reed and Hall Effect sensors that require Gauss ratings two times higher or even more. In Stock. The x is a cross-product, which means that the magnitude (size) of the force is found from Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field.There are a variety of effects that can be called magnetoresistance. the use of a magnetic shield to deflect the magnetic flux flow (see Figure #22); (Figure #22. Magnetic scales longer than 40" long are built from a thicker extrusion called the S2. Cashback. SMC offers a variety of auto switches for actuators and air grippers.
