  • The 5 Key Advantages of Magnetic Latching Solenoids
    enable latching force without the need for permanent magnets or constant power. Closing the valve is done through the application of an electric pulse of a lower current with a different polarity than that used to open it. Unlike permanent magnet latching solenoids, which can be latched manually

  • Timing the operation of control systems associated with rotating equipment
    This tends to rule out the use of electrically-operated mechanical latches, in which the latch is tripped by operation of the supply to a small solenoid , and also the use of "plugging" and forced -field methods. (b) Time- constants of all devices in the circuits should be reduced to a minimum.
