90JA・90JB● 90JA: Potentiometer outside-mounted ● 90JB: Potentiometer incorporated ● With conductive plastic element● Nomenclature
S means special mechanicalspecifications not applicableto our standards. ●● 90 means approx. size of base housing in mm.
● J means joystick controller.
● A means kind of type :A : 1,2 or 3-dimensional coordinate is available and also means
Potentiometer outside-mounted type.
B : 1,2 or 3-dimensional coordinate Potentiometer is incorporated inside thehousing.
● M : means round type
● Y means kind of mechanism : X 1-dimensional coordinate.
Y : 2-dimensional coordinate. Z: 3-dimensional coordinate.
4 and more numbers : Over 4-dimensional coordinate.
● Available directions of lever operation
Standard version:
O : Omni-directional 360°operating type.
Special version:
I : I figure (Y) directional operating type.
L : L figure(+Y, +X only) directional operating type.
X : Cross directional of X and Y operating type.
Q : Square-directional 360°operating angle.
T : In addition to omni-directional 360°operation, this type is 3-dimensional
coordinate operation by rotating knob in which a potentiometer isincorporated.
U : In addition to square-directional 360°operation, this type is3-dimensional coordinate operation by rotating knob in which apotentiometer is incorporated.
S : Special operating directions other than the above-mentioned types.
