  • Which bus, when?
    It's now easier to see which kind of industrial bus best serves particular industries and applications. Connectors from Lumberg Inc., Midlothian, Va., are tailored for industrial Ethernet. The hybrid design combines an RJ45 electrical connection with the common M12/M18 shell, and protects against
  • Receiving Inspection of Data Bus Couplers
    and observe results. Button 1 - go/no-go test. Checks for shorts between stub conductors and shield. Button 2 - measures the resistance of the stub cable and transformer winding. It should be between 1 and 5 ohm depending on the coupler. Button 3 - go/no-go test. Checks shorts between bus conductors
  • Quantum leap for digital cable
    Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a potential component for quantum computers using electronic vibrations on a microfabricated aluminum cable that transfers information between two "artificial atoms. " The assembly looks like a miniaturized
  • Protecting the Universal Serial Bus from Over Voltage and Overcurrent Threats (.pdf)
    This application note addresses the various requirements for protecting the Universal Serial Bus (USB) from overcurrent and over voltage environmental threats.The solutions presented cover both USB 1.1 and the higher speed USB 2.0 circuitry. Specific emphasis is placed on USB 2.0 with information
  • The Cable Distribution Rules You Need to Obey
    The key advantage of a cable carrier is that bus and motor cables, pneumatics, electrics and hydraulics can all be guided safely in one system. However, correctly arranging each cable and hose within your chosen cable carrier according to the recommended spacing requirements is vital if you want
  • CAN-do Cable Solutions for Many Applications (.pdf)
    First introduced in 1986 for automotive applications, CAN (controller area network) is a multi-master broadcast serial bus standard for networking, controlling and monitoring electrical and electronic devices. It requires no central computer and allows devices connected through an ECU (electronic
  • Detecting Circulating Currents and Hot Spots in Normally Non-current Carrying Conductors and Structural Members
    Often normally non-current carrying conductors, conduits, or even structural members contain circulating currents that are induced by currents flowing in adjacent conductors such as cable or bus. There is usually no way to measure the magnitude of these currents, and sometimes it is difficult
  • Various Interfaces for Rotary Encoders
    via one cable. There is no need to connect each component with the master. The bus cable runs simply from one component to another. Specific protocols, such as Device Net, Can Bus, Profibus, Ethernet, etc. "organize" the communication between the bus components. Benefits: In addition to cost
