Rodless cylinders are pneumatic drives and – as the name suggests – do not have a piston rod. Although they don't have a piston rod, they execute linear movements, which is why they are also known as linear drives. Rodless cylinders are used wherever a short installation length is advantageous and where the force has to be absorbed as consistently as possible. They also allow much longer travel distances with strokes of up to 8.5 m, which is not feasible for a standard cylinder with piston rod.
When you add brakes or sensors directly on the cylinder, reliable switching becomes essential. Use cylinder sensors as pneumatic actuator limit switches: these cylinder end position sensors (often used as limit switches for pneumatic cylinders) detect the piston magnet—typically via a reed switch for pneumatic cylinder—to provide consistent signals. They act as pneumatic cylinder end-of-stroke sensors and a dependable cylinder limit switch option.
