1. Purchase a zero backlash flexible shaft coupler that
accommodates the diameter of the sensor shaft (Item
1) on one end and the dancer arm pivot shaft on the
other end (See Figures 4 and 7).
2. Slide the shaft coupler onto the dancer arm pivot shaft,
inserting the shaft no further than half the thickness
of the coupler clamp; then, tighten the clamp around
the shaft (See Figure 4).
3. The orientation of the Dancer Position Sensor (Item1)
must be as shown in order to match the mid output of
the Dancer Position Sensor to the mid travel position
of the dancer arm (See Figure 5). The DPS60A Dual
sensor has two measurement ranges allowing for
flexibility the in mounting position (See Figure 7).
4. Attach Dancer Position Sensor (Item 1) to one of
the three hole configurations on the Bracket (Item 3)
with the two shorter Pan Head Screws (Item 4), Flat
Washers (Item 6), and Lock Washers (Item 5) (See
Figure 4).
5. Hand tighten the screws just enough to prevent sensor
from moving during installation
(See Figure 4).
6. Slide the Dancer Position Sensor (Item 1) into the
coupling (See figure 4).
7. Measure the distance from the bottom of the Bracket
(Item 3) to the machine’s side frame. Fabricate a
spacer block to make up the distance between the
Bracket and the machine’s side frame (See Figure
4).
8. Slide the Dancer Position Sensor (Item 1) into the
coupling again
with the spacer block in place on the
machine’s side frame and mark the location for the
bracket’s two mounting holes.
9. Remove the Dancer Position Sensor (Item 1) and
Bracket (Item 3); then, drill and tap two 8-32 threaded
holes centered within the marks drawn in Step 8.
10. With the dancer arm held firmly in its mid travel
position, slide the Dancer Position Sensor (Item 1)
into the coupling again making sure the sensor shaft
marking is pointing toward the cable.
Insert the shaft no further than half the thickness of
the coupling clamp.

12. Using customer supplied 8-32 screws and lock
washers, secure the Bracket (Item 3) to the customer
supplied spacer block and the machine’s side frame
(See Figure 4).
