Infrared Sensor Kit for Automatic Gates and Security Systems Wide compatibility for multiple applications: This infrared sensor kit provides an effective detection range from 1 ft 6 in to 39 ft, making it suitable for automatic driveway gates, garage doors, security access systems, and similar installations where precise object detection is essential. Enhanced safety with automatic stop function: The system instantly halts gate movement when an obstacle is detected, helping prevent injury, vehicle damage, or harm to pets. Ideal for households, commercial properties, and industrial sites where safety is a priority. Fast, accurate obstacle detection: Equipped with an 890 nm infrared beam and an adjustable tracking angle from 0 to 45 degrees, the sensors monitor a wide area and trigger responses in less than 0.5 seconds. This rapid detection ensures gates operate reliably even in busy or risk environments. Built to withstand challenging weather conditions: Featuring an IP44 waterproof rating and a durable casing, the kit delivers dependable performance in rain, snow, and direct sun. Designed to operate in temperatures from 13°F to 131°F, it remains fully functional yearround. Practical use scenarios: 1. Residential driveways where gates need to stop instantly when a car, person, or pet approaches. 2. Commercial properties with automated vehicle entry systems requiring fast detection to protect equipment and personnel. 3. Garage doors with automated closing mechanisms where obstacle detection prevents accidental damage. This infrared sensor kit combines precise detection, rapid response, and robust construction to deliver safe, reliable operation for a wide range of gate and door automation projects.
