1 Pneumatics Symbols DIN ISO1219-1, 03/96. Graphic symbols for pneumatic equipment. Circuit symbols are used through this catalogue and on the labels of most The situation also occurs when SMC develop new product systems for SMC Pneumatic products. which an ISO or JIS symbol does not exit. Examples include the MGZ high power cylinder or the AV series air operated soft start / release valve. In There are several symbol systems and conventions in use around the this situation either a composite symbol showing a representative circuit is world, most officially recognised by standards bodies.

2 Commonly used is used, or the nearest standard symbol is modified by SMC. ISO1219-1. For assistance a table below shows both ISO symbols, which may differ The symbols found in this catalogue generally conform to the Japanese from JIS symbols in this catalogue, and common ISO/JIS/SMC Symbols. Industrial Standard (JIS) in many cases, there is no difference between JIS and ISO circuit symbols. Volume 1.
