Part Numbering System

RA20 Series

RA 20 Y L 10 S B 203 K

NOTE: FMS = From Mounting Surface

ꢀ

Resistance Tolerance: K = 10% (standard).

ꢀ

J = 5% (special order).

ꢀ

G = 2% (special order).

ꢀ

F = 1% (special order).

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., 200 = 20Ω; 201 = 200Ω; 202 = 2,000Ω;

203 = 20,000Ω). See table for standard resistance values.

For Single Unit:

Specify taper and resistance code as shown.

For Ganged Tandem 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: B203A503 or if both units are the same: B203X2

Resistance Taper: B = Linear.

A = CW Audio (logarithm).

C = CCW Audio (logarithm).

Shaft End Style: S = Slotted.

F = Flatted.

R = Round.

Standard Shaft Length: 10 = 10mm FMS.

15 = 15mm FMS.

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