What is the difference between the old CQ2/CDQ2 series and the new CQ2-Z/CDQ2-Z series, and are the cylinders interchangeable? In particular, when replacing a CDQ2B32-30D for maintenance, is the current part number interchangeable with the new one?

The current part number for the old CDQ2B32-30D is “CDQ2B32-30DZ.” For this product, the auto switch mounting rail on the body has been changed to a round auto switch mounting groove. Cylinder body mounting is possible. A mounting bracket may be required if the auto switch in use is to be used as is. Check the auto switch model first.
