The conductive plastic sensor of the angle-index potentiometer is designed

which adopts the conductive plastic as sensitive material

the brush discreteness insures the pressure invariableness on the conductive plastic film by the brush patch

and its source uses 10V high precision constant current and voltage.This sensor has high resolution

precision

dependability

anti-jamming ability and long life etc.It may be used in the atrocious weather

the measuring range is 345°

it may rotate freely in 360°with 5×（1±5%）kΩ of the origination resistance and 0.01°of the resolution and ±0.3% of the linearity

it may be applied to control the clique digit and hydraulic pressure pump and robot etc.
