Vibrating Solenoid OAC Vibrating solenoids of the OAC series are solenoids with UI core shape and two excitation windings connected in series. They are primarily in- stalled in spring-mass-systems. The peak forces given in the table refer to operational temperature and 90 % of the rated voltage with a reference temperature of 35°C. Peak force F = magnetic force reached at nominal air gap in non-vibrating state. By means of vibrating solenoids directional, linear oscillations of the utilization equipment are generated. Fields of Application Oscillating conveyor drives Bunker drives Linear conveyor drives Coil and bobbin are encapsulated in casting resin.
Therefore, they are not susceptible to moisture and dust and suitable for rough conditions. The oscillating direction is determined by the geometrical arrangement of the springs in the spring-mass system. The effective amplitude here corresponds to twice the amplitude of the oscillating frequency of the whole system. Vibrating solenoids are infinitely adjustable by the ope- rating voltage. They reach the full conveying power immediately upon switching on, and there are no troublesome starting and stopping effects of unbalance drives.
