About this item
A Rotor Sensor Disc (often called a Pulse Disc, Tone Ring, or Reluctor Wheel) is a circular metal disc with precisely cut slots, holes, or teeth that works in combination with a sensor (like a magnetic pickup or Hall effect sensor) to detect rotational speed and position.
🔧 Where it is used in two-wheelers (bikes/scooters):
-
ABS (Anti-lock Braking System): The rotor sensor disc is mounted on the wheel hub or brake disc. As the wheel rotates, the slots/teeth pass by the ABS sensor, generating signals to monitor wheel speed.
-
Engine/Crankshaft Positioning: In some motorcycles, a similar disc is attached to the crankshaft or camshaft to help the ECU determine ignition timing and fuel injection.
⚙️ How it works:
-
The disc has evenly spaced teeth or slots.
-
A sensor reads the interruptions as the disc rotates.
-
These signals are converted into pulses, which the ECU/ABS module uses to measure speed, rotation, or position.
📌 Key Functions:
-
Helps ABS prevent wheel lock during sudden braking.
-
Provides real-time wheel speed to ECU.
-
Used in synchronization of ignition and fuel systems in engines.
