Professional Manufacture 100% Duty Cycle 4.5m Two Fence Arm for Blocking Car and People

Motor Drive System: Features a DC variable frequency control motor paired with a robust connecting rod transmission mechanism and a balancing spring system. This design ensures exceptionally stable, smooth, and reliable operation. Key components are engineered for longevity, with the motor rated for up to 6 million cycles and the balance spring for 500,000 cycles.

Advanced Safety - Obstacle Detection: Incorporates an intelligent auto-reversing function upon obstacle contact. If the boom encounters any obstruction during its downward closing motion, it will immediately and automatically reverse direction to prevent damage and enhance safety.

Integrated Safety & Power: Designed to seamlessly support external safety accessories, including radar detectors, loop detectors, and infrared photoelectric beams for comprehensive anti-crashing protection. For added convenience, it features a built-in DC 12V power output, which can be used to directly power external devices like radar sensors, simplifying installation.

Communication & Connectivity: Offers flexible communication options. It supports standard RS485 communication for integration into centralized control systems. Additionally, it allows for RS485 off-line connection, enabling the linking of multiple barriers for synchronized operation without a central controller.
