Retro-Reflective Infrared Sensor IRR-7R | Safety Sensor for Automatic Doors

^{_{The Retro-Reflective Infrared Sensor IRR-7R is a high-precision safety solution designed specifically for automatic doors, industrial doors, rolling shutters, and gate automation systems. Using advanced retro-reflective infrared technology, the IRR-7R detects moving or stationary objects by emitting an infrared beam toward a reflector and monitoring interruptions caused by obstacles. This one-side installation design eliminates the need for a separate transmitter and receiver, making the sensor easier to install, more cost-effective, and highly reliable in both residential and commercial applications. With its long sensing distance and stable signal performance, the IRR-7R enhances door safety by preventing accidental closures, protecting vehicles, equipment, and pedestrians in everyday operation.}}

^{_{Engineered for durability and long-term performance, the IRR-7R features an IP65 waterproof enclosure, ABS+PC hardened housing, and built-in protection against reverse polarity, overload, and short circuits. Its wide voltage range of 10–30VDC ensures compatibility with most door controllers, while the relay NO/NC output supports seamless integration with existing automation systems. The sensor’s fast response time makes it ideal for high-speed doors and environments requiring immediate detection. With included mounting hardware and a high-efficiency reflector plate, the IRR-7R is easy to align and install, even in outdoor or high-vibration environments. Whether used for safety compliance, system upgrades, or new automation projects, the IRR-7R Retro-Reflective Infrared Sensor provides a dependable, long-range, and maintenance-friendly solution for modern automatic door systems.}}
