5.3 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 5-5)
Note: For Fisher actuators model 657 & 667 sizes 34 thru 70, Westlock 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.
