Actuator module

Abstract

The present invention relates to the axial (R) AX The present invention relates to an actuator module (1) comprising an airtightly sealed module housing (3) whose longitudinal direction extends to the module housing (3), wherein the actuator module (1) comprises at least one piezoelectric actuator (2) disposed within the module housing (3), and at least electrical terminals (6a, 6b) for the piezoelectric actuator (2) that pass through the module housing wall (3w), and in the actuator module (1), the module housing between the piezoelectric actuator (2) and the module housing wall (3w) The internal space (3i) of the module housing (3i) electrically insulates the module housing wall (3w) from the piezoelectric actuator (2) and includes a potting compound (4) formed in such a way that heat conduction occurs, particularly using a heat conduction aid, and the module housing wall (3w) of the module housing (3) has a bellows (10, 20, 30, 40) having a corrugated contour (10, 20, 30, 40), and at least one section (14, 34l, 34r, 44l, 44r) of the corrugated contour (10, 20, 30, 40) is axial (R AX ) is formed in a spiral shape. The present invention further relates to a weighing system (50) comprising such an actuator module (1).
