Fluxus product names that start with the letter "F" (for example, FA Series pneumatic magnetic grippers) use a switchable magnetic technology called active shunting. The innovative Fluxus F magnetic housing architecture is comprised of five essential components: an aluminum housing, two steel poles, and two cylindrically shaped, diametrically polarized rare earth magnets. The magnets are positioned on top of each other with the lower magnet in fixed position aligning the north pole of the magnet to one steel pole and the south pole of the magnet to the other steel pole. The upper magnet is positioned directly above the lower magnet. The upper magnet can be rotated 180°. When the north pole of the upper magnet is positioned above the south pole of the lower magnet, the assembly is effectively off as the magnetic flux is completely contained in a circuit between the two poles. When the upper magnet is rotated 180°, the north pole is above the north pole of the lower magnet and the two magnets work together as one with the steel poles working to distribute the magnet flux into a target workpiece.

The FA Series is a group of pneumatic switchable magnet grippers meaning they are magnets that turn on and off, and are operated by compressed air inputs. These products use a rotary pneumatic actuator with a drive shaft shaft coupled to an upper magnet in an F style magnetic housing. The rotary actuator has two positions: 0° and 180°.  When the actuator is at 0°, the magnet assembly is in the off position.  When air is supplied to the "A" airport, the actuator rotates to the 180° position and the magnet is on.

Applications for FA Series products include but are not limited to pick and place, bin picking, stamping press transfer, automotive body-in-white assembly, automotive powertrain component handling, and clamping fixtures.
