Typical Constructions
The following is basic information on the most
common CTS 15/16" (24mm) diameter composition
variable resistor constructions supplied to our
customers. Space limitations prohibit showing the
virtually thousands of additional constructions fabricated to exacting customer specifications. For your
special applications the CT
S engineering staff is
at your disposal for designing the best and most
economical construction to meet your requirements.
Vernier Constructions
This construction is designed for fine tuning
applications. It provides precision adjustments
in 3700
° (10 turns) or 2000° (5 turns)
