Part Numbering System
B 102 K
NOTE: FMS = From Mounting Surface
Resistance Tolerance: K
= 10% (standard).
J
= 5%;
G
= 2%; or
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. R indicates decimal point for resistance
less than 10Ω (i.e., 5R0 = 5Ω; 100 = 10Ω; 101 = 100Ω; 102 = 1,000Ω;
103 = 10,000Ω ).
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:
B102A503
or if both units are the same:
B102X2
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:
B102A503B104
or if all units are the same:
B102X3
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: 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.
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 100 C.
X
= 30 C to 100 C.
Size: 30
= 30mm Diameter.
Center Tap: T
= With Tap;
Blank
= Without Tap.
