In the web catalog on the SMC website, there are series names with "10-" and "25A-" prefixes. What do these numbers mean?

"10-" corresponds to clean/low particle generation, and "25A-" corresponds to semi-standard products for use in secondary battery manufacturing facilities. Please contact SMC for details on the numeric symbols prefixed to series names as well as for the specifications of each series. Note that products with a 2-digit number prefixed to the part number are limited in number.
