Just finishing up a project that used a pneumatic rotary cylinder actuator (rack and pinion inside) I found the symbol for that, but I can't find the symbol for the cylinder that has the magnetic piston ring for external switch detection of the stroke.
Maybe there isn't one yet or I have to make one up
If any has any idea I would appreciate an inkling.
I would like to update my symbol library.

A schematic drawing of the piston is two thin lines. The magnetic core is symbolysed by a thick line between the two thin lines. Source: Festo catalogue.

Carel, Thanks, I saw that for the 'normal' type cyclinder, but they don't show it when used with the rack and pinion style, Just the cylinder symbol itself http://catalog.festo.com/enu/asp/Def...D=197373&L=001

Yes, I looked this up. My post was derived from the magnetic coupled cilinder. It looks like you have to assume a rack and pinion cilinder has a magnetic piston. But: the piston has a magnet, the pinion not. So you sense the piston, not the rack. This is indirect, so problaby not tolerable for the schematic fundamentalists. So a drawing with separate sensors would suffice, but would not reflect the movement of the pinion.

Sorry, dont know how to edit posts, but end of line 2 should read as: So you sense the piston, not the pinion.
