About the Airtac TWG Stop Cylinder TWG40X25SC
TWG40X25SC combines the simplest TWG40 head, the C round rod stopper, with the S magnet option on the Dia 40 mm double acting stopper cylinder. The 25 mm stroke moves the stop up and down, the flange mounting sets the stopper height on the machine, and the round rod head gives a single point of contact at the leading edge of the load.
Key data: PT1/8 ports, 0.15-1.0 MPa operating pressure with 1.5 MPa (215 psi) proof, -20 to +70 C temperature range, bumper cushion, and air filtered by a 40 um element. The magnet works with position sensors, and the catalog impact load and speed charts are the reference for sizing this bore against your application.

How to choose
Compared with its code siblings, TWG40X25SC keeps the magnet but changes the head: TWG40X25SB uses a flat rod, TWG40X25SR a roller, and TWG40X25SK a lever roller with an adjustable oil shock absorber. TWG40X25C drops the magnet for builders who detect position externally, and the F self-lock is offered only with the K lever roller.
Applications
Tote stop on a belt line
The round rod head stops tote bins on a conveyor while the S magnet signals stopper position to sensors on the frame.
Pick station release
Double acting air gives a positive 25 mm lift, releasing one tote at a time to the operator at a picking position.
Workpiece locator
The adjustable flange height aligns the round rod with a fixture stop point on a manual assembly station.
FAQ
What are the specifications of TWG40X25SC in one place?
Dia 40 mm bore; 25 mm stroke (+1.0/0); round rod stopper with magnet; double acting; PT1/8 port; 0.15-1.0 MPa operating pressure; 1.5 MPa (215 psi) proof pressure; -20 to +70 C; bumper cushion; no lubrication required.
What does the SC ordering code tell me?
In the TWG ordering system S stands for magnet and C for round rod stopper, so SC is a round rod with magnet. Drop the S for no magnet (TWG40X25C), or choose B flat rod, R roller, or K lever roller with adjustable oil cushion. Stroke tolerance is +1.0/0 mm.
