Feature:
1. A double-wall housing design creates an air gap between inner and outer shells, reducing mechanical noise transmission from the motor and gears into the vehicle cabin.
2. A center-shaft mounted wiper-type commutator uses silver-palladium alloy brushes, providing arc-free switching and consistent torque across temperature extremes.
3. A compound planetary gear train provides three-stage torque multiplication, achieving final output force of 8kgf at the actuator rod with a 12V, 5A input.
4. The position feedback uses two hall-effect sensors rather than mechanical contacts, eliminating contact bounce and wear for infinite cycle life.
5. An automatic reset feature returns the actuator to neutral position after each lock/unlock pulse, preventing over-travel and ensuring consistent latch engagement.
