Intended to make push force of proportional current intensity in control systems of hydraulic gear in working benches, engineering and transport vehicles. Electromagnets have installed armature position sensor that is withdrawn to a single socket. Position sensor is induced and differential. Hysteresis is less than 5%, in state variable feedback systems is less than 1%. Electromagnets with proportions 60x60mm have installed data processing equipment and electromagnet control equipment with ability of manual start with no-voltage condition.
