ER series electromagnets are linear, with a simple effect: the movement along the route from the initial position to the final position is made by the action of electromagnetic forces and the return to the initial position is achieved by external forces or by a spring incorporated into the electromagnet. The useful force is obtained from the magnetic force (Fm), adding or subtracting the weight of the moving core. The values for the magnetic force (Fm), depending on the route, are obtained under the following conditions:
The connection terminals are arranged as shown in the following image. They can be assembled in different positions and dimensions to order, and the terminals can be replaced by free conductors.
