Explanation of High-Speed Door Photoelectric Switch

Key Technical Parameters and Performance Highlights

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.

   Light Source and Alignment: Adopting a 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: Fully sealed design, waterproof and dustproof, suitable for industrial environments with moisture and dust (such as logistics warehouses, workshops).

   Response Time ≤ 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 two action modes (light - on / dark - on), flexibly matching different control logic requirements.

   Adjustable Sensitivity: 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. Environmental Adaptability

   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: Wiring lead - out type design (05, 2m cable length), no complex wiring required; the shell is made of heat - resistant ABS material, impact - resistant and corrosion - resistant, reducing later maintenance costs.

• Safety Compliance: The relay output has a physical isolation function, meeting industrial safety standards, and can be directly connected to the high - speed door safety control system, complying with CE and other certification requirements.
