DJI MATRICE 200 V2 Matrice 200 V2 Arm Locking Failure

Frame Arm Adapter Assembly

This structural component houses the Hall-effect sensor and the locking sleeve. Mechanical wear or vibrations often cause the sensor to shift out of alignment or fail internally, preventing the flight controller from detecting a secure lock even when the arm is physically engaged.

Arm Lock Sensor Flex Cable

The signal from the arm sensor travels through a high-flex ribbon cable at the hinge axis. Repeated folding cycles can cause fatigue-induced micro-fractures in the conductive traces, resulting in an intermittent or permanent 'unlocked' signal to the main flight controller.

Arm Locking Ring Magnet

The rotating locking collar contains a permanent magnet that triggers the sensor upon rotation. If this magnet becomes dislodged due to impact or adhesive failure, the sensor will never register the 'locked' state despite the mechanical collar being fully rotated.
