2" Versatile Configurations

Sleeve and Ball Bearing Linear and Nonlinear
These high precision, external phasing potentiometers are completely self-conntained and suitable for use as single or multiple section units without special shafts or other specialized construction. Two types are available: Sleeve bearing C-200 or ball bearing BC-200. Additional performance characteristics of the ball bearing model include lower starting and running torque, improved linearity because of reduced radial shaft play, minimized backlash between ganged potentiometer sections for more accurate function repetition or solution of mathematical equations.

Ganging is accomplished on the job by novel drive pin and spring tension pickup combinations which are supplied with each potentiometer. Accurate mating surfaces permit precise ganging of multiple units. One piece stainless steel clamp equipped servo mounting plates are available for servo or three-hole mounting.

Precise 360-degree external phasing permits independent rotation of each ganged potentiometer for accurate individual or related adjustment even after installation.

An exclusive feature of this series is a one-piece molded insulation. Terminal board, tap mounting ring and al internal insulating surfaces are molded directly into precision machined aluminum housing. Unit terminals are permanently cored into position with molded identification numerals. This technique provides a complete insulating envelope inside the housing without joints or interruptions, and eliminates all possible leakage paths. The one-piece molded interior also provides better concentricity than individual fabricated strips, resulting in more uniform wiper pressures, improved linearity and operational life.

Models C-200-E and BC-200-E with 180° terminal board are available. The extended terminal board increases the area between tap terminals and provides space for mounting shunts and resistors directly to the potentiometer body without additional wiring or space consuming auxiliary resistor panels.

2" SINGLE SHAFT AND DOUBLE SHAFT UNITS AVAILABLE

C-200 SINGLE HOLE MOUNTING
Single hole mounting for direct connection to a panel or bracket is accomplished with an extended threaded bushing is accomplished with an extended threaded bushing passing through the structural member. When a precise reference location must be maintained, a non-turn pin can be supplied for this purpose. Internal tooth lockwashers and hexagon locknuts are standard mounting hardware ( specify model C-200-P)

UNIVERSAL SERVO MOUNTING ADAPTERS
Universal servo mounting adapters provide positive three-screw fastening to a panel or gear box, or direct connection to a servo drive. Adapter plates have individual shafts, bearing and pickup couplings for direct connection to the drive pin end of the potentiometer. Servo mounting adopters feature a precision machined locating hub and are supplied with stainless steel clamp rings.

NONLINEAR FUNCTIONS
The C-200 and BC-200 design readily lends itself to nonlinear functions. Moderate slopes are possible by shaping the card, or space winding on straight sided cards. More severe slopes are obtained by combining these tow methods. Adding wire diameter changes makes it possible to accomplish extreme slopes. One feature of these models is the application of sine-cosine functions. High accuracy is possible with the precision shaped cards and space winding. Two independent functions are accomplished by insulated collectors and brushes phased 90° apart. Nonlinear potentiometers can be ganged with linear or other nonlinear functions to achieve additional outputs from a single shaft movement.
