Soleno I D S

●The desired attraction force can be provided.
The attraction force matching to the actual load can be
provided by changing the shapes of the mating sections of the
movable and stationary iron cores.
●The exciting current is constant regardless of the stroke.
The exciting current of an AC solenoid varies depending on
the stroke. With a DC solenoid, however, the exciting current is
determined by DC resistance only and is constant regardless
of the stroke.
●Operation noise is reduced.
If there is a clearance between the movable and stationary
iron cores of an AC solenoid, the coil may be burnt. In the case
of a DC solenoid, its exciting current is constant regardless
of the clearance of the movable and stationary iron cores.
Therefore, a shock-absorbing material can be provided
between the movable and stationary iron cores to reduce
operation noises.
●No buzzing noise is generated.
DC solenoids do not generate the buzzing noise AC solenoids
generate due to the pulsating attraction force.
●Constant operation time.
The operation time of the DC solenoid is constant regardless
of the frequency. This is because it is driven by direct current.
●Long life is ensured.
The service life of the solenoid depends greatly on the amount
of mechanical wear between the movable iron core and the
guide (pipe). The sliding section of the guide is specially
