INTRODUCTION

INSTALLATION

Nexen Dancer Position Sensors have been designed to accurately measure the rotational movement of a dancer arm.
This family of sensors use Hall Effect technology which provide for benefits such as infinite resolution, low drag, and
no mechanical wear. They are ideally suited to work with Nexen’s Dancer Position Controllers.

NOTE: Mounting of the Dancer Position Sensor can

be accomplished two ways. The first is the Direct

Connection method and the second is the Coupling

Connection method. Review the instructions for both

methods and select the method best suited for your

application.

NOTE: For serial number prior to 2269020, refer to

Literature 21260.

DIRECT CONNECTION

1. Verify that the dancer arm pivot shaft’s end complies

with the dimensions given (See Figure 1).

2. Drill and tap two 4-40 threaded holes 90° apart for

two, .25” set screws.

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 2). The DPS60A Dual
sensor has two measurement ranges allowing for
flexibility in the 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
two shorter Pan Head Screws (Item 4), Flat Washers
(Item 6), and Lock Washers (Item 5). (See Figure 3).

5. Hand tighten the screws just enough to prevent it from

moving during installation (See Figure 3).

6. Slide the Dancer Position Sensor (Item 1) into the shaft

until the Bracket (Item 3) contacts the machine’s side
frame (See Figure 3).

7. Mark the location of the Bracket’s two mounting

holes.

8. 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 7.

9. With the dancer arm held firmly in its mid travel

position, slide the Dancer Position Sensor (Item 1) into
the shaft while making sure the sensor shaft marking
is pointing toward the cable (See Figure 3).

10. Using the two set screws, secure the dancer pivot

shaft to the sensor shaft by tightening the screws
evenly.

11. Using the two longer Pan Head Screws (Item 7) and

Lock Washers (Item 5), secure the Bracket (Item 3)
to the machine’s side frame (See Figure 3).
