AC Solenoids
Compared to DC solenoids, AC solenoids are characterised by the following decisive advantages and disadvantages:

Advantages:

High dynamics during the switching operation
Large strokes (up to 45 mm)
Automatic reduction of power consumption in the end position
No rectifier necessary
Disadvantages:

Limited number of switching operations per hour
High noise emission when reaching and remaining in end position
If, due to a mechanical failure, the armature does not reach the end position, the winding may burn, unless adequately protected.
As nowadays, direct current dominates as standard supply voltage for components, the applications for AC solenoids are limited to spare parts requirements and special applications where the required strokes cannot be realised otherwise and noise emission plays a minor role.
