Cylinder Magnet Polarity
S = South Pole facing LDT - Typical
N = North Pole facing LDT
Note: It is important to identify the 
polarity of the magnet installed in the 
cylinder. Most Pneumatic cylinder 
manufactures typically install the 
magnet with the South Pole facing 
out, but we have experienced both 
North and South Pole magnets.
