Which type of sensor is used to count yaw position?

• A. Capacitive sensors
• B. Infrared sensors
• C. Inductive sensors
• D. Catalytic sensors

Answer: (C)

Counting yaw position relies on detecting discrete angular steps from a rotating encoder. An inductive sensor is well suited for this because it senses a metallic target such as a toothed encoder wheel without contact, producing a pulse each time a tooth passes. Those pulses can be counted to track the angular position as yaw. Inductive sensing is robust to dust, oil, and vibration and works well in metal, harsh environments, which is why it’s commonly used for rotary encoders. Capacitive sensors detect proximity to dielectric targets and aren’t as reliable for metal encoder counts; infrared sensors require a clear optical path and can be affected by dust or lighting; catalytic sensors detect gases, not position.
