Resistance Tolerance: K =

10% (standard).

Resistance Code: Expressed in ohms. A three digit code where the first

two digits are significant figures, and the third digit indicates the number

of zeros that follow these figures (i.e., 100 = 10

Ω;101 = 100Ω;102 = 1,000Ω;

103 = 10,000

Ω;105 = 1,000,000Ω). See table for standard resistance values.

For Single Unit:

Specify taper and resistance code as shown.

For Ganged Tandem Unit or Dual Unit:

Specify a taper code and resistance code for each unit starting with

the front unit followed by the rear unit. If both units have the same taper

and resistance codes, add “ X2” suffix per example below.

Examples: B103A503 or if both units are the same: B103X2

Resistance Taper: B = Linear.

A = CW Audio (logarithm).

C = CCW Audio (logarithm).

Shaft End Style: S = Slotted; F = Flatted; R = Round.

For Single Shaft:

Specify the shaft length (FMS) and shaft end style as shown.

For Dual Concentric Shafts:

Specify the shaft length (FMS) and shaft end style for the inner shaft

followed by the shaft length (FMS) and shaft end style for the outer

shaft. Use a dash (-) to separate the code groups for the inner and

outer shaft specifications. Example: 30R-20R

Standard Shaft Length: 10 = 10mm FMS.

15 = 15mm FMS.

Up to 30mm shaft length available (special order ).

Switch Type: MH = SPDT, 110VAC, 0.5A, Rear Exit Lug Terminals.

SH = SPST, 110VAC, 0.5A, Rear Exit Lug Terminals.

Blank = No Switch.

Detent: - 4C = Center Detent.

Blank = No Detent.
