The IR33 is an infrared sensor engineered to enhance the safety and reliability of barrier gate operations. It serves as a vigilant guardian, constantly monitoring the area in front of the barrier gate to detect the presence of vehicles. By doing so, it triggers the necessary responses to ensure the barrier gate’s boom rises and falls in a coordinated manner, avoiding potential collisions that could damage property and disrupt traffic flow.
Working Principle and Key Functions
The IR33 operates based on the principle of infrared detection. It emits infrared rays at a specific frequency (1.92KHz) and wavelength (940nm).
During the lowering process of the boom, if the infrared sensor detects pedestrians or vehicles staying in the monitoring area, the door opener control system will immediately stop the boom from lowering to prevent it from hitting pedestrians or vehicles. Once the pedestrians or vehicles leave the monitoring area, the infrared beam barrier returns to normal, and the receiver steadily receives infrared light again. The signal processing circuit will detect the stable electrical signal and send a stop signal, after which the door opener control system will decide whether to continue lowering the boom or maintain other states according to subsequent instructions.
Technical Specifications
Power Supply: The IR33 is designed to be versatile in terms of power input, accepting 12V - 24V AC/DC power. This wide range of power compatibility allows it to be integrated into various access control systems without the need for specialized power sources.
Max Range: With a maximum detection range of 15 meters, the IR33 can cover a relatively large area in front of the barrier gate. This ensures that even in scenarios where vehicles are approaching from a distance or where the barrier gate spans a wide opening, the sensor can effectively detect their presence.
Infrared Frequency and Wavelength: Operating at an infrared frequency of 1.92KHz and a wavelength of 940nm, the IR33 is optimized for accurate and reliable detection. These specific parameters enable the sensor to cut through environmental interference and precisely identify the presence of vehicles.
Input and Output: The sensor has an input of RX 15mA and TX 30mA, and a relay output of 1A max 36V. This relay output allows it to communicate effectively with the connected door opener, sending the necessary signals to control the barrier gate’s operation.
Application Realms
The IR33 is widely used where barrier gates operate:
Parking lots: Prevents barrier booms from closing on cars, avoiding vehicle and gate damage.
Coordinates gate opening/closing during vehicle payment stops, ensuring smooth traffic and less waiting.
Industrial sites (e.g., factory entrances, loading docks): Stops collisions between vehicles/equipment and barrier gates, boosting workplace safety and efficiency.
Conclusion
In summary, the IR33 Infrared Sensor is essential for access control systems. Its advanced infrared tech, flexible power input, long detection range, and specific installation needs make it a reliable way to stop vehicle - boom collisions. Whether in parking lots or industrial areas, it safeguards property and improves traffic management efficiency. As access control technology advances, the IR33 stands as a model for dependable vehicle detection, key to safer and more efficient vehicle access.
