Note: The Pneumatic cylinder must have a magnet in order
to work. Each cylinder manufacturer uses different types
of magnets. In most cases the cylinder supplier installs the
magnet so that the South Pole is facing out. To date, we
have successfully worked with most brands of pneumatic
cylinders. Consult AMETEK APT for a list of compatible
cylinder manufacturers. Call 800.635.0289 to speak with
a Sales Engineer.
