AC operated solenoids have an in-rush current, providing a high initial stroke force, and can utilise longer strokes than DC solenoids for the above reason.
AC laminated solenoids may 'hum' in operation, depending on the application conditions. It is important to ensure that the armature (plunger & yoke) be allowed to seat, otherwise over-heating of the solenoid coil may occur.
