Pneumatic Cylinders with Locking System and Digital Measuring Detector

This product is the result of having linked to a pneumatic actuator both the digital position detector and the integrated safety locking system. The system does not need to be connected to the moving part of the mechanism as it generates by itself the movement by means of an internal pusher with bidirectional pneumatic function. This pusher, operated by a 5-way microvalve, moves autonomously until it meets the obstacle and measures the position. The detection of the position is obtained by transforming the translation movement of the piston rod in a rotation movement of the screw by means of the coupling of screw-female screw; the encoder transforms the rotation (mechanical size) in sequences of electric pulses and establishes the relation between number of turns and number of pulses. The piston and the body of the actuator encoder must be fixed; i.e., must not move in regards to the rotation of the screw.
