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. R indicates decimal point for resistance less than 10Ω (i.e., 5R0 = 5Ω; 100 = 10 Ω ; 101 = 100 Ω ; 102 = 1,000 Ω ; 103 = 10,000 Ω ). 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 (RA25YPR model has knurled end style.) 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 ). Style: Blank = 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. PR = Panel Mount, Single Unit, Single Knurled 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. D = Panel Mount, Dual Unit, Dual Concentric Shaft, Right Angle Ear-Lug Terminals on Each Unit. Operating Temperature Range: Y = X= Size: 25 = 25mm Diameter.
