Model CT-23, front of panel mounting, digital turnscounting 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.

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-23 MOUNTING INSTRUCTIONS

Drill or punch panel. See suggested hole pattern below. Insert potentiometer in panel. Mount potentiometer in panel with nut and lockwasher supplied
with the potentiometer. Turn the potentiometer shaft counterclockwise to obtain minimum
resistance or voltage ratio not necessarily at the end of travel . Loosen set screw in knob with allen wrench. Set the dial readout
to Slip the dial carefully over the potentiometer shaft. Tighten the
set screw without causing movement of the dial readout or potentiometer shaft.

CT-26 MOUNTING INSTRUCTIONS

Drill or punch panel. See suggested hole pattern below. Insert turns-counting dial in panel cutout and secure with
mounting nut. Secure locator plate to potentiometer bushing using two hex
nuts. Turn the potentiometer shaft counterclockwise to obtain minimum
resistance or voltage ratio not necessarily at the end of travel . Loosen set screw in turns-counting dial with allen wrench. Set
the dial readout to 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 " mm .
