SFA-E-SA20
Thin and lightweight Easy to install to steering shafts
SFA-E-SA20 steering sensors adopt strain gages to detect steering force (torque) and has built-in amplifier. Also, rotary encoders in steering sensors measure steering angle with high resolution. In addition, the dedicated indicator displays steering force and angles.
Key Features
Rotary encorder measures steering angle with high resolution
Built-in amplifier ensures stable steering force output with minimal influence of external noise
Dedicated indicator is separately available
