The sensor expert EGE offers a wide range of inductive proximity switches for demanding industrial environments which cause malfunctions in standard sensors. Interference fields, which can be caused by sensor and motor power supply lines wired in parallel via frequency inverters, by digital mobile radio networks, wireless high-frequency signal transmission or power line communication, do not cause any problems for these sensors. Sensors from the blue series fulfill EMC requirements above and beyond those of the relevant standards (e.g. EN 61000-6-4, EN 61000-6-2). In addition to standards compliance tests, the sensors also pass a wide range of tests especially developed by EGE which simulate common electromagnetic interferences in industrial environments. They are therefore especially suited for installation in the close proximity of strong electromagnetic interference sources, such as frequency inverters and motors.
