Explanation of High-Speed Door Photoelectric Switch

Các thông số kỹ thuật chính và điểm nổi bật về hiệu suất

1. Detection Capability

   Detection Distance: 0.5 - 20m, covering the common door opening width of high - speed doors, and supporting stable identification of opaque objects (minimum 60mm), avoiding the risk of missed detection due to too small objects.

   Nguồn ánh sáng và căn chỉnh: Nhận lấy một 650nm red light source with a visual alignment design, workers can intuitively judge the optical path calibration during installation, greatly improving installation efficiency.

2. Response Speed and Reliability

   False Action Prevention: The algorithm is optimized for high - reflective objects (such as metals, glass) to avoid false triggering caused by reflection.

   Strong Light Resistance: It can withstand 11,000lx strong light (sunlight) and 3,000lx incandescent light irradiation, adapting to stable work in outdoor or strong light environments.

   Protection Class IP68: Thiết kế kín hoàn toàn, không thấm nước và chống bụi, thích hợp cho môi trường công nghiệp có độ ẩm và bụi (như kho hậu cần, xưởng).

   Thời gian phản ứng ≤20ms: Adapted to high - frequency switching scenarios of high - speed doors (multiple actions per second), ensuring that signals are triggered immediately when objects intrude, avoiding the door body from pinching people or objects.

   Anti - Interference Design:

   
   

   

3. Electrical and Control Compatibility

   Power Supply and Power Consumption: 12 - 24VDC wide voltage input, maximum power consumption 4VA, adapting to the common power supply system of high - speed door controllers.

   Output and Action Modes: Relay output (safety isolation design), supporting Light ON / Dark ON hai chế độ hành động (bật sáng / tối), linh hoạt phù hợp với các yêu cầu logic điều khiển khác nhau.

   Độ nhạy điều chỉnh: Through the sensitivity adjuster, the detection threshold can be fine - tuned according to the on - site environment (such as dust, fog) to optimize stability.

4. Khả năng thích ứng môi trường

   Wide Temperature Operation: - 20 - 65ºC (operation) / - 25 - 70ºC (storage), adapting to severe cold and high - temperature areas.

   Humidity Tolerance: 35% - 85% RH (no condensation), suitable for long - term operation in humid environments.

Scenario - Specific Advantages and Value

• Special Optimization for High - Speed Doors: Solves the problem of "no failure of photoelectric devices when high - speed doors switch", ensuring stable signals during the high - speed operation of the door body, and avoiding door jams or safety accidents caused by photoelectric failures.

• Easy Installation and Maintenance: Thiết kế loại dây dẫn ra (chiều dài cáp 05, 2m), không cần dây phức tạp; vỏ được làm bằng vật liệu ABS chịu nhiệt, chịu tác động và chống ăn mòn, giảm chi phí bảo trì sau này.

• Tuân thủ an toàn: Đầu ra rơle có chức năng cách ly vật lý, đáp ứng các tiêu chuẩn an toàn công nghiệp và có thể được kết nối trực tiếp với hệ thống điều khiển an toàn cửa tốc độ cao, tuân thủ CE và các yêu cầu chứng nhận khác.
