Ordering Information (potential combinations)
20SG2AC–G2AC-P
Series 20: Mechanical Encoder, concentric shafts
Seal: S = Sealed; A = Not Sealed
Output code
Angle of throw (outer shaft)
Stop arrangement: AC = all positions continuous rotation;
AF = all positions with fixed stop between first and last;
02 to 15: number of positions, if less than maximum
Termination: P = Pins; 02 to 25 = Cable Length
Stop arrangement (see above)
Angle of throw (inner shaft)
Output code
Output Code:
G = Gray
B = Binary
Q = Quadrature
Angle of throw / max positions:
2 = 22.5° / 16 positions
0 = 30°/ 12 positions
6 = 36°/ 10 positions
5 = 45°/ 8 positions
