Incorporates the latest mechanical technology (rack and pinion design) to give long service life with light weight and high performance. The unit will spring back to its rest position in the absence of air making it great for fail safe applications. Features include end of stroke adjustment, visual Indicator, namur interface and ISO mounting interface. Options include IP67 limit switch box with visual Indicator, Namur (direct mount) solenoid valves and a range of inserts to step the drive down.
