Ultrasonic single beam reflex light curtain

Ultrasonic single beam reflex light curtains, also known as ultrasonic through-beam barriers or ultrasonic retro-reflective sensors, are non-contact detection devices that use high-frequency sound waves to detect the presence or absence of objects. These sensors operate typically at frequencies between 40 kHz and 200 kHz, with sensing ranges from a few centimeters up to several meters, depending on the model. They are designed for single-beam operation, meaning they emit a focused ultrasonic pulse and detect the reflected echo from a target or a fixed reflector. Key technical specifications include beam angle, response time (often in milliseconds), output type (PNP/NPN, analog, or switching), and protection rating (IP65/IP67). They are immune to ambient light, dust, and color variations, making them ideal for challenging environments.

These ultrasonic single beam reflex light curtains are widely used in industrial automation for object detection, level measurement, presence sensing, and collision avoidance. Common applications include packaging lines, material handling systems, conveyor belts, and automated guided vehicles (AGVs). They are also employed in liquid level monitoring in tanks, web break detection in printing presses, and safety guarding in machinery. Their ability to detect transparent, shiny, or dark objects without interference from dust or fog makes them suitable for harsh environments like woodworking, metalworking, and food processing plants.

The main subcategories within this product range include ultrasonic sensors with fixed or adjustable sensing ranges, analog output models (0-10V or 4-20mA), and switching output models (NO/NC). Key article codes often follow a pattern like ULT-40-200 (indicating 40 kHz frequency and 200 mm range) or ULT-200-2000 (200 kHz, 2 m range). Common codes include ULT-40-100, ULT-80-500, and ULT-200-2000, each specifying the operating frequency and maximum sensing distance. These codes are typically structured as [Frequency in kHz]-[Range in mm], allowing engineers to quickly identify the sensor's capabilities.
