A gripper device having a body formed with a piston chamber in which a piston is reciprocally mounted. Connected to the body are a pair of spaced fingers. A cross bar is connected to the piston and oppose toggle links interconnect the ends of the cross bar to the adjacent fingers so that actuation of the piston effects the operation of the fingers between an open and closed position. A first sensor device is disposed between the fingers to measure the lateral distance therebetween, and a second sensor is disposed between the body and a movable cap supported thereon to measure longitudinal displacement between the cap and associated body.
