Where is it?

If the application requires knowledge of load position, proximity sensing devices can usually be added to the barrel of the cylinder. They will "make" when a magnet on the piston inside the cylinder passes them. Since the distance from the magnet to end-of-rod is known, this will locate the load.

There are a variety of position sensing options for cylinders including reed switches, hall effect switches, linear potentiometers, or you can elect to sense the position of the load itself by using a barrel proximity switch mounted so that the switch "makes" as the load itself arrives.

1. If you need position sensing, make sure the cylinder you choose has that capability both in terms of magnets on the piston, and external mounts for the switch itself.
2. And there you have it - six steps to finding the right cylinder. Good luck in your hunt. What do you need to know to select the right air cylinder from the huge variety available in the industrial marketplace? Here is the answer.

How much force do you need to move the object you wish to move? You'll need to know the weight of the object. Consider what the object being moved is sliding and know that this friction is adding to the load.

Oversize the required force of the cylinder by 25% to take into account friction of the rod and piston seals within the air cylinder itself, and also allowing a safety margin as it relates to the expected load the cylinder will see.

Know your available air pressure (example: 90 PSI) and multiply that times the surface area of the piston inside the cylinder to get the theoretical output force of the cylinder.
