Dongfeng KInland truck parts Central locking actuator 3660020-C0100

Equipped with a 12V high-torque DC motor (rated power 8W), the actuator delivers a maximum output torque of 1.2 N·m—sufficient to drive the Kinland’s heavy-duty door lock mechanism (designed for commercial vehicle door thickness and seal resistance). The motor features a copper commutator and high-grade carbon brushes, ensuring stable power transmission and a service life of 50,000+ lock/unlock cycles (equivalent to 8–10 years of average use). It operates at a no-load speed of 3,500 rpm, enabling fast lock action (full stroke: 15mm) in 0.3–0.4 seconds—critical for preventing door security risks (e.g., incomplete locking during quick stops). The motor also supports reverse rotation (for unlock action) with consistent torque output, ensuring symmetrical performance in both lock and unlock directions

Engineered to withstand the harsh conditions of door-mounted operation—moisture, road salt, and constant vibration—the actuator achieves an IP65 protection rating. The outer casing is made of impact-resistant PBT plastic (UL94 V0 flame-retardant grade) with a tight-sealing rubber gasket, blocking water intrusion from door rain channels or car washes (tested to 30 minutes of water spray at 30 psi). The internal gear train uses precision-machined nylon gears (glass fiber-reinforced for wear resistance), reducing friction and ensuring smooth operation even after 10,000+ cycles of vibration testing (10–2000Hz, 15g acceleration)—common in truck operation on unpaved roads. Additionally, the motor windings are coated with high-temperature enamel (180°C class), enabling reliable operation in door temperature extremes (-40°C to 85°C), from frigid winters to hot summer afternoons

To safeguard the actuator and Kinland’s central locking system from damage, the unit integrates dual protection mechanisms. A built-in overload protector cuts off power to the motor if the lock mechanism jams (e.g., due to frozen door latches or debris in the lock), preventing motor burnout or gear stripping. The protector resets automatically once the jam is cleared, avoiding the need for manual intervention. An overheat protection switch activates when the motor temperature exceeds 120°C (caused by prolonged operation or short circuits), shutting down the motor until it cools to a safe temperature (≤80°C). These features meet ISO 16750 automotive electrical safety standards, ensuring the actuator does not pose fire risks or damage the vehicle’s electrical system

Designed for easy installation by fleet technicians or auto repair shops, the actuator simplifies replacement with user-friendly features. It uses the Kinland’s original mounting holes and hardware—no drilling or welding required—and comes with pre-installed mounting clips that snap into the door’s bracket in seconds. The lock rod connection uses a quick-release plastic clip, allowing technicians to attach/detach the factory lock rod without tools (unlike traditional threaded connections that require pliers). The 2-pin connector is plug-and-play, matching the door’s wiring harness perfectly—no cutting, soldering, or coding needed. Installation takes 20–30 minutes per door: remove the door panel, disconnect the old actuator, attach the new unit to the lock rod and connector, and reattach the panel. Each unit undergoes 100% torque testing, waterproof verification, and cycle life checks, backed by a 24-month warranty against defects (e.g., motor failure, gear wear, water leakage)
