A pneumatic gripper, comprising a shell which forms an internal gripper compartment wherein a pneumatic actuation group and an electronic board for commanding and controlling the pneumatic actuation group are housed, two gripping jaws commanded by the pneumatic actuation group so as to be translatable along a jaw translation axis (X) between a jaw opening position and a jaw closing position, wherein the pneumatic actuation group comprises: - an internal body wherein two pneumatic chambers are obtained, which extend along respective chamber axes (Y) parallel to each other and to the jaw translation axis (X), a jaw actuation piston being slidably housed in each pneumatic chamber, each pneumatic chamber being divided by the respective piston into a jaw closing chamber and a jaw opening chamber (26", 26a"), each jaw being rigidly connected to a respective actuation piston; - cartridge solenoid valves housed in respective valve seats obtained in the internal body and suitable to control the passage of air from an inlet port to the jaw closing and opening chambers and from the jaw closing and opening chambers to one or more discharge ports; - a transducer shaft which extends with possibility of axial rotation along a shaft axis (W) perpendicular to the chamber axes (Y) in a shaft seat obtained in the internal body , the transducer shaft being operatively connected to the jaw actuation pistons so as to be rotationally actuated by the translation of the jaw actuation pistons; and wherein the electronic board for commanding and controlling the pneumatic actuation group is provided with: - electrical connection means suitable to create an electrical connection with the cartridge solenoid valves ; - a position sensor operatively coupled to the transducer shaft; - at least two chamber pressure sensors suitable to measure the air pressure in the jaw closing and jaw opening chambers, respectively. - an internal body wherein two pneumatic chambers are obtained, which extend along respective chamber axes (Y) parallel to each other and to the jaw translation axis (X), a jaw actuation piston being slidably housed in each pneumatic chamber, each pneumatic chamber being divided by the respective piston into a jaw closing chamber and a jaw opening chamber (26", 26a"), each jaw being rigidly connected to a respective actuation piston; - cartridge solenoid valves housed in respective valve seats obtained in the internal body and suitable to control the passage of air from an inlet port to the jaw closing and opening chambers and from the jaw closing and opening chambers to one or more discharge ports; - a transducer shaft which extends with possibility of axial rotation along a shaft axis (W) perpendicular to the chamber axes (Y) in a shaft seat obtained in the internal body , the transducer shaft being operatively connected to the jaw actuation pistons so as to be rotationally actuated by the translation of the jaw actuation pistons; - electrical connection means suitable to create an electrical connection with the cartridge solenoid valves ; - a position sensor operatively coupled to the transducer shaft; - at least two chamber pressure sensors suitable to measure the air pressure in the jaw closing and jaw opening chambers, respectively. <EOS>
