Balluff BALLUFF GmbH company was founded in 1921, in the broad field of industrial applications, particularly in the field of machinery and equipment to provide users with innovative, experienced sensor use of the program. Is a worldwide leading manufacturer of sensor products, including a complete electronic and electromechanical limit switch series, photoelectric switches, inductive proximity switches, capacitive switches, linear displacement sensors, RFID identification systems, and a variety of connectors products. Non-contact position sensing, no wear, high reliability, and this is the advantage of inductive proximity switches. Balluff offers a complete set of inductive proximity switches, from miniature to large: cylindrical housing from 3mm to M30, square shell from 5 * 5mm to 80 * 80mm. Inductive proximity switches were not worn in any case, is usually applied to the machine tool manufacturing, plastics industry, textile industry, wood processing industry and car manufacturing industry - almost all from the automation industry standard, the long-range type to the "attenuation factor 1" type, Balluff offers solutions always meet your application needs. Standard DC 3- / 4- wire standard DC 2- wire attenuation factor of all metal materials testing one pair of sensing distance coincidence detection distance : from standard to extended-type anti-harsh environments for welding applications, anti-magnetic field influence on weld star for hydraulic cylinders used in high temperature environments, high pressure up to 500bar for the food and chemical industries
