Part Numbering System
NOTE: FMS = From Mounting Surface
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 = 10Ω; 101 = 100Ω; 102 = 1,000Ω;
103 = 10,000Ω; 105 = 1,000,000Ω ).
See table for standard resistance values.
Resistance Taper: B
= Linear.
Shaft End Style: S
= Slotted.
F
= Flatted.
R
= Round.
Standard Shaft Length: 15
= 15 mm FMS.
20
= 20mm FMS.
Up to 50mm shaft length available (special order ).
Shaft Lock: L
= With Shaft Lock.
Blank
= Without Shaft Lock.
Size: 201
= 20mm Diameter.
