Karm4 Pro 24V Light Duty Articulated Arm Swing Gate Opener 250KG Access Control Anti-Pinch Protection For Industrial Park Use
Silver / Black Options
Fits Different Environment Themes
Multiple Installation Methods
Fits Various Door Opening Directions and Positions
KEYDEONE Karm4 Pro Series Side-Mount Electric Door Opener is available in two versions: Articulated Arm and Sliding Arm. The Articulated Arm version supports both push and pull opening. In some inward-opening installations where the side clearance from the wall is limited, the wall may obstruct the articulated arm during operation. In this case, the Sliding Arm version is recommended. For installation options, please refer to the diagram above or contact our sales team for confirmation.
DC Brushless Motor
High Torque for More Door Types
Karm4 Pro is equipped with a 24V 65W high-power DC brushless motor. Combined with a 1:200 gearbox, it delivers up to 90 Nm of torque and can drive doors up to 2 m high, 2 m wide, and within 250 kg.
Intelligent Obstruction Rebound
Safer Access Every Time
Karm4 Pro Series door openers feature built-in obstruction rebound. When the door meets resistance during operation, it automatically stops and moves in the opposite direction:
1.Obstruction during closing → stops → reopens
2.Obstruction during opening → stops → recloses
⚠️: A microwave anti-pinch sensor can be used on the rear side of the door opening direction. On the front side, since the microwave sensor cannot distinguish pedestrians from the door itself, it may prevent the door from closing properly. Therefore, a human detection anti-pinch sensor must be used.
Dual-Door Linkage Interface
Linked Opening for Double Doors
The Karm4 Pro Series includes a dual-door linkage interface, supporting automatic linked opening for double doors and unequal double doors. Operation logic:
1.Double doors: after receiving an opening signal, both doors open and close simultaneously.
2.Unequal double doors: after receiving an opening signal, one door opens first, followed by the other.
Outdoor Rain & Dust Protection
Heat and Cold Resistant for Harsh Environments
The Karm4 Pro Series Side-Mount Electric Door Opener is built for outdoor use with dust and rain protection. Tested by KEYDEONE Lab, the motor operates reliably in extreme temperatures from -86°F to 149°F, ensuring stable performance in both northern and southern regions.
Compatible with Multiple Access Controls
Enjoy Smart Door Opening
KEYDEONE Karm4 Pro is compatible with card, fingerprint, face recognition, microwave, and human detection access control devices on the market. It can also connect to Wi-Fi or 4G mobile remote opening and smart home control modules. Existing access control devices can be reused, or you may contact customer service to purchase compatible accessories from our store.
Compatible with Multiple Door Locks
Enhanced Security with Lock Integration
Karm4 Pro Series door openers use a gear-driven motor structure, so the door can still be pushed open by force after closing. If locking is required, it can be used with 12V-triggered locks such as magnetic locks, electric bolt locks, smart locks, and horizontal electric locks. Compatible with 80% of access control locks on the market. Please contact customer service for details.
