MODE Ⅱ Actuator | Precision Bi-Directional HVAC Air Mode Control | Fast Response, Ultra-Quiet
Manufacturer: Zhengzhou Junchi Tech Co., Ltd.
Product Category: Automotive HVAC Actuators / Air Distribution Systems
Application: Air Mode Doors (Face/Foot/Defrost), Dual-Zone Climate Control, Vent Direction Regulation
Product Overview
Zhengzhou Junchi Tech Co., Ltd. is proud to launch the MODE Ⅱ Actuator, a high-performance electromechanical device engineered for precise bi-directional control of automotive air distribution systems. As a critical component in modern Vehicle Climate Control assemblies, this actuator manages the positioning of mode doors to direct airflow to the windshield (defrost), face vents, or footwells with exceptional speed and accuracy.
Designed to meet the rigorous demands of both traditional and New Energy Vehicles (NEVs), the MODE Ⅱ features a robust bi-directional rotation capability (90° clockwise and anticlockwise), allowing for versatile integration into complex HVAC linkage systems. With an ultra-fast response time of approximately 3 seconds per 90°, it ensures immediate cabin comfort adjustments when drivers change settings. Combined with an industry-leading noise level of ≤43 dB(A) and a high lock torque of >1.5 N·m, the MODE Ⅱ Actuator represents the pinnacle of reliability, silence, and efficiency in automotive climate control.
Key Features & Technical Advantages
1. Rapid Bi-Directional Response
Unlike unidirectional actuators that require a full reset cycle, the MODE Ⅱ Actuator supports direct clockwise and anticlockwise rotation within a 90° operating angle. This bi-directional capability, coupled with a swift operation duration of 3.0 ± 2.0 seconds (no-load), allows for instant air direction changes, enhancing the user experience by eliminating lag between command and action.
2. Superior Locking Torque – Safety
Safety and stability are paramount in air door control. The MODE Ⅱ delivers a Lock Torque exceeding 1.5 N·m at 12V. This high holding force ensures that mode doors remain securely in position against high-velocity airflow pressure, preventing unwanted drift or “flapping” noises during vehicle acceleration or sudden wind gusts, even without continuous power application.
3. Ultra-Quiet Operation (NVH Optimized)
In the pursuit of a serene cabin environment, noise reduction is critical. The MODE Ⅱ Actuator achieves a whisper-quiet performance level of ≤43 dB(A) under no-load conditions. This is significantly lower than many standard actuators, ensuring that mode transitions are virtually silent to passengers, a key requirement for premium and electric vehicle segments.
4. High Efficiency – Low Power Consumption
Optimized for energy conservation, the actuator draws less than 0.1A under rated load (0.3 N·m) and only 0.05A max at no-load. This low current draw reduces the strain on the vehicle’s electrical system and minimizes heat generation within the dashboard assembly, contributing to overall system longevity and fuel/energy efficiency.
5. Robust Connector – Electrical Integrity
Reliability extends to the physical interface. The MODE Ⅱ features a reinforced connector design tested to withstand a static load of 98N in multiple directions (stretching and vertical) without malfunction. With an insulation resistance of >5MΩ, it guarantees electrical safety and signal integrity even in humid or vibrating environments.
