Continuous Dutysearch for term

Solenoid ON continuously without interruption for periods of about 30 minutes or longer. With no OFF time to allow the coil to cool, continuous duty Solenoids must have coils wound to limit the current drain and must be large enough to provide for adequate heat radiation to prevent coil burn-out. A continuous duty Solenoid will be considerably larger than an intermittent design to produce the same force / stroke.
