3.3 Mounting Positioner on a Linear Actuator
Step 1. Mount the magnet assembly to the stem of the actuator. A coupler block
normally is needed to extend the magnet assembly outside the yoke area and into the
sensing range of the magnetic pick-up unit.
Step 2. Fasten the mounting bracket to the actuator.
Step 3. Mount the positioner to the mounting bracket. The positioner should be
mounted so the magnetic pick-up unit of the positioner is centered between the limits of
the magnetic assembly’s stroke. After mounting the positioner, the magnet assembly
should be within 1/8” from the back of the positioner (1/16” is ideal), (See Figure 3-7)

Note: For Fisher actuators model 657 & 667 sizes 34 thru 70, Westlock Controls can
supply a slotted mounting kit design. This will allow the user to easily center the
positioner sensor between the limits of the magnet assembly’s stroke. Other mounting
kits are available upon request.
