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

For Triple Unit:

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

the front unit followed by the middle and rear units. If all units have the

same taper and resistance codes, add “ X3” suffix per example below.

Examples: B103A503B104 or if all units are the same: B103X3

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 Shaft:

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: 15 = 15 mm FMS.

20 = 20mm FMS.

Up to 50mm shaft length available (special order ).

Switch Type: ME = SPDT, 110VAC, 1A, Rear Exit Lug Terminals.

MF = SPDT, 110VAC, 3A, Rear Exit Lug Terminals.

SE = SPST, 110VAC, 1A, Rear Exit Lug Terminals.

SF = SPST, 110VAC, 3A, Rear Exit Lug Terminals.

Blank = No Switch.

Style: N

= Panel Mount, Single Unit, Single Shaft, Right Angle Ear-Lug

Terminals.

L

= Panel Mount, Single Unit, Single Shaft with Shaft Lock,

Right Angle Ear-Lug Terminals.

G

= Panel Mount, Ganged Tandem Unit, Single Shaft, Right Angle

Ear-Lug Terminals on Each Unit.

GL = Panel Mount, Ganged Tandem Unit, Single Shaft with Shaft

Lock, Right Angle Ear-Lug Terminals on Each Unit.

T

= Panel Mount, Triple Unit, Single Shaft, Right Angle Ear-Lug

Terminals on Each Unit.

D

= Panel Mount, Dual Unit, Dual Concentric Shaft, Right Angle

Ear-Lug Terminals on Each Unit.

Operating Temperature Range: Y =

10 C to

85 C.

Size: 24 = 24mm Diameter.

Center Tap: T = With Tap; Blank = Without Tap.

TOCOS Series Name: RV = Carbon Film Element.

NOTE: FMS = From Mounting Surface
