Key Notes:

• Part Numbers: AT439507
• Replaces: AT433986 (superseded)
• Type: Rotary Hall effect sensor — angular position
• Weight: 0.13 lbs (0.06 kg)
• Function: Reads the angle of a rotating component and sends a position signal to the machine's controller, with no contact parts to wear out
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the machine logs a position or angle sensor fault code, a function controlled by the sensor responds erratically or not at all, or the displayed position doesn't match the machine — a failed sensor sends a bad or missing signal to the controller.
