Koganei CDAS20X25-R-ZE135A2 Jig Cylinder – Ø20 mm Bore, 25 mm Stroke, with Rubber Bumper
The Koganei CDAS20X25-R-ZE135A2 is a compact, double-acting Jig Cylinder from the Koganei C Series, with a Ø20 mm bore and a 25 mm stroke. It has a built-in rubber bumper (-R) that absorbs impact at the end of the stroke, reducing noise and wear. It also has a built-in magnet and comes with two ZE135 solid-state sensor switches with 1000 mm leads. The sensor switches sit inside the body grooves, so nothing sticks out once they are fitted.
What the Part Number Means
- C – Koganei Jig Cylinder C Series
- DA – Double acting
- S – Cylinder with built-in magnet for sensor switches
- 20 – Ø20 mm bore

Why Choose the Bumper Version
On the standard C Series cylinder, the piston stops directly against the covers. The -R version adds rubber bumpers that soften the impact at both stroke ends. This lowers noise and vibration and protects the cylinder and the load in fast-cycling applications. The bumper adds 10 mm to the overall length compared with the standard version.
