The DOtech product line from Germany-based NK-Elektronik are test transmission systems consisting of two send/receive units connected by an fiber optic cable transmission lines. Signals can be transmitted in both directions. The digital transmission lines boast freedom from potentials, negligible emissions, and high immunity to electromagnetic fields and interfering currents. Developed for testing in electrically-harsh automotive environments is also well suited to other industrial applications such as precise transfer of voltage readings from temperature and strain measurement strips. DOtech products include transmission lines for digital transfer LINBUS and CANBUS high- and low-speeds CAN with two and four channels, as well as the analog transmission line U53. Its frequency range is DC to 10 MHz.Find more product information at the emv GmbH website.
