A
linear actuator (1) in the form of an electric reversing solenoid, comprising a cylindrical
metal housing (2) in which two magnetic coils (3, 3') are housed and which
metal housing (2) guides an armature element (4) axially displaceable along its central axis (A), wherein the armature element (4) is movable between a first end position (push) and a second end position (pull) by a
stroke length (H). The cylindrical
metal housing (2) is covered at its end faces by a first (7) and a second (7') shunt element. The electronic controls are housed in an additional
enclosure (12) to which a connector element (13) is provided for supplying power to the magnetic coils (3, 3') and the electronic control, as well as for transmitting control signals and communication data.Two Hall sensors (15, 15') are integrated in the center of the metal housing (2), arranged in the
transverse plane T and in different radial directions (R1, R2). These Hall sensors are located adjacent to the first and second permanent
magnet elements (16) fitted into the armature element (4) at the respective end positions of the armature element (4). Together with these
magnet elements (16), they form a
detector pair to generate a
switching signal at these positions. To increase the positioning accuracy (g) of the armature element, the position of the individual elements (15, 16) of the respective
detector pairs is individually adjusted relative to each other such that the
signal steepness of the
signal step in the output
signal is maximized in the region of the respective end position. For further precision in switching accuracy, a switching point for controlling the magnetic coils is defined in the steepest part of this signal step.
