Corrosion Protection (ASTM B 117)

The level of protection from gradual destruction of materials, (usually metals), by chemical reaction with its environment. The salt spray test is a standardized test method used to check corrosion resistance of coated samples—testing procedure and testing parameters are standardized under national and international standards, such as ASTM B 117. These standards describe the necessary

Continuous Duty

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


The copper windings on the Solenoid that provide an electrical element through which a current is passed to generate a magnetic field. During the winding process, a precision wound coil follows a prescribed pattern in which each turn is laid precisely beside the previous turn. This allows the maximum amount of copper to be wound
