Bourns

Model CT-23, front of panel mounting, digital turns-

counting dial saves valuable internal space. Highly accurate, it will

enhance the man/machine interface of any control panel. Easy to

read white on black numerals provide excellent legibility and

accurate readings within 1/500 of a turn.

CT-23 MOUNTING INSTRUCTIONS

1. Drill or punch panel. See suggested hole pattern below.

2. Insert potentiometer in panel.

3. Mount potentiometer in panel with nut and lockwasher supplied

with the potentiometer.

4. Turn the potentiometer shaft counterclockwise to obtain minimum

resistance or voltage ratio (not necessarily at the end of travel).

5. Loosen set screw in knob with allen wrench. Set the dial readout

to “000.”

6. Slip the dial carefully over the potentiometer shaft. Tighten the

set screw without causing movement of the dial readout or

potentiometer shaft.

Bourns

Model CT-26 recessed mounting digital turns-counting dial,

counterpart to the Bourns Model CT-23, provides a lower panel

profile. The design simplifies installation requiring only one panel

hole. The CT-26 maintains the same high level of symmetry,

legibility and accuracy of its counterpart.

CT-26 MOUNTING INSTRUCTIONS

1. Drill or punch panel. See suggested hole pattern below.

2. Insert turns-counting dial in panel cutout and secure with

mounting nut.

3. Secure locator plate to potentiometer bushing using two hex

nuts.

4. Turn the potentiometer shaft counterclockwise to obtain minimum

resistance or voltage ratio (not necessarily at the end of travel).

5. Loosen set screw in turns-counting dial with allen wrench. Set

the dial readout to “000.”

6. Slip the potentiometer shaft into the turns-counting dial, insuring

that the notch in the locator plate is over the pin at the rear of the

dial. Tighten the set screw without causing movement of the dial

readout or potentiometer shaft.

For mounting, the maximum recommended panel thickness is

1/8 " (3.1 mm).
