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 = 10Ω; 101 = 100Ω; 102 = 1,000Ω;
103 = 10,000Ω; 105 = 1,000,000Ω ).
See table for standard resistance values.
Resistance Taper: B
= Linear.
A
= CW Audio (logarithm).
C
= CCW Audio (logarithm).
Shaft End Style: S
= Slotted (standard for 15mm or 20mm shaft length).
F
= Flatted (special order for 20mm shaft length only ).
Standard Shaft Length: 15
= 15 mm FMS.
20
= 20mm FMS.
Up to 30mm shaft length available (special order).
