24V reversible electromechanical operator for swing gates for pedestrian and vehicular access, for use in homes and apartment buildings. Its small size means it can be installed on small pillars and columns (minimum width required 8cm). The slide arm option means constraints such as walls and obstacles close to the operator can be overcome. The limit switch function is regulated by the absolute encoder. The safety of the operator is guaranteed thanks to the D-track system which precisely determines the position and force with which the gate moves, using the friction inside the operator and the new articulated and slide arms with anti-shear design.
