Genuine AirTAC adjustable mounting height stopper cylinder, order code TWG40X30SC from the TWG40 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The AirTAC TWG40X30SC pairs the C round rod stopper with a Dia 40 mm bore, 30 mm stroke (tolerance +1.0/0 mm) and the S magnet in one double acting TWG series stopper. The round rod gives a simple, narrow contact point for stopping pallets, boxes and workpieces on conveyor lines, and the magnet lets position sensors report whether the stopper is up or down.
Mounting is a flange with adjustable mounting height, so the stop point can be set on the machine frame at assembly. The thicker piston rod of the Dia 40 body resists impact, air is switched through the PT1/8 port at 0.15-1.0 MPa, and the series runs dry from -20 to +70 C without lubrication.

TWG40X30SC is the magnet-equipped round rod choice of the 30 mm Dia 40 family. Use TWG40X30C without the S if no sensor signal is needed, TWG40X30SB for a flat rod face, TWG40X30SR for a roller stopper with magnet, or the lever roller K code when a softer, cushioned stop matters. The F self-lock applies only to lever roller stoppers.
The round rod presents a defined stop point for pallets on conveyor runs, with the magnet confirming stopper position to the controller.
Use the adjustable mounting height flange to set the Dia 40 round rod at the right height for stopping workpieces feeding assembly stations.
With the S magnet built in, this code suits gated conveyor sections where a sensor must verify each raise and lower cycle before the next load moves.
Dia 40 mm bore, 30 mm stroke (+1.0/0 mm tolerance), double acting, round rod stopper, magnet included, flange with adjustable mounting height, PT1/8 port, operating pressure 0.15-1.0 MPa, proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, bumper cushion, no lubrication required.
The C selects the round rod stopper and S adds the magnet. The same bore and stroke with a flat rod is TWG40X30SB, with a roller TWG40X30R, and the lever roller K code is the only stopper that accepts the F self-lock and adjustable oil cushion options.
