Electromagnetic Transmissions Solenoids Holding Magnets

Solenoids for simple operation
Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass.

Solenoids for double maneuvering
Double or double coil electromagnets are intended for control applications. During the respective power up, the action of one of the two coils attracts the through core. They are available in folded sheet design and machined in the mass.

Monostable solenoids
Single-solenoid electromagnets are intended for applications requiring a maintenance-free position for reasons of energy saving or safety. The core is attracted by the magnetic field of the coil during power up and remains maintained by the magnetic field delivered by the permanent magnet. Then a simple inversion of the polarity of the power supply makes it possible to neutralize the magnetic field of the magnet which has the effect of releasing the core.

Bistable solenoids
The bistable solenoid consists of two coils and each coil draws by energizing the through core. The magnetic field delivered by one of the two permanent magnets maintains the position. It is then necessary to reverse the polarity of the closed kernel side coil to cancel the magnetic field of the magnet. And also feed the other coil to attract the nucleus in the other direction.

Electromagnetic suckers
The cylindrical electromagnetic sucker makes it possible to keep a ferromagnetic part under tension by closing the magnetic field by the poles. In the absence of power supply to the suction pad coil, the electromagnetic force is canceled and the ferromagnetic part comes off.

Electromagnetic bars
Of parallelepipedal shape, the electromagnetic bar allows the maintenance under tension of a ferromagnetic part by closing the magnetic field by the poles of the part to maintain. In the absence of supply of the coil of the bar, the electromagnetic force is canceled and the ferromagnetic part comes off.

Permanent magnet section cup
Cylindrical, the permanent magnet section cup allows the maintenance of a ferromagnetic part thanks to the magnetic field delivered by the integrated permanent magnet which ensures a de-energized behavior. The magnetic field delivered by the power supply cancels the magnetic field of the magnet thus freeing the workpiece. The attraction force induced by the magnet is again present at the power failure of the coil.

Permanents magnets bars
Of parallelepipedal shape, the permanent magnet bar allows the maintenance of a ferromagnetic part thanks to the magnetic field delivered by the integrated permanent magnet which ensures a de-energized behavior. The magnetic field delivered by the power supply cancels the magnetic field of the magnet thus freeing the workpiece. The attraction force induced by the magnet is again present at the power failure of the coil.
