25A-C(D)QS, Compact Cylinder, Standard

The CQS compact cylinder is available for those small-bore cylinder applications where saving space is a concern.  The CQS offers standard long strokes (up to 300mm) in four bore sizes from 12 to 25mm.  Long stroke versions incorporate a wear band and thicker piston to handle the increased bearing needs of the longer strokes.  Both switch capable and non-switch capable body styles are the same, and switches can be mounted on threee (12-16 bore) and four (20-25 bore) sides.  An increased side load version (CQS*S) is available for more demanding applications.

The 25A- series variations are designed using material compatible with secondary battery applications and are able to be used in low dew point environments.  The variations eliminate copper (Cu) and zinc (Zn) material where possible, making them compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types.
