The ISUB500-18GM40 Series is a high-performance, short-range ultrasonic distance sensor designed for precise detection in industrial automation. Operating at a high frequency of 200kHz, this sensor delivers superior resolution and stability compared to standard low-frequency models. Its compact M18 short-housing design makes it the ideal solution for space-constrained applications where reliability cannot be compromised.
Unlike optical sensors, our ultrasonic technology is unaffected by target color, transparency, or surface texture. Whether you are monitoring the liquid level of chemicals, detecting clear glass, or controlling roll diameters in web processing, the ISUB500 provides consistent, non-contact measurement data.
Key Features & Technical Advantages
High-Frequency Precision (200kHz): The 200kHz operating frequency significantly reduces noise interference and improves detection accuracy for small or fast-moving objects within the 0.5m range.
Minimized Blind Zone: With an ultra-small blind zone of just 0...40mm, this sensor allows for detection very close to the sensor face, maximizing the usable range in tight machinery.
Robust M18 Short Housing: The nickel-plated brass housing offers industrial-grade durability while maintaining a compact footprint, perfect for retrofitting into existing production lines.
Advanced Output Options: Available in Analog (4-20mA / 0-10V) for continuous measurement or Switching (NPN/PNP) for presence detection.
Intelligent Teach-In Function: Easily set the sensing window limits (A1 and A2 points) via the teach-in wire, allowing for custom detection ranges tailored to your specific application.
Industrial Protection: Rated IP67, the fully sealed unit resists dust, oil, and water ingress, ensuring longevity in harsh factory environments.
Ideal Applications
This high-precision sensor is engineered for versatility across various sectors:
Web Tension Control: Accurately monitors roll diameter changes in winding/unwinding processes for film, paper, and foil, ensuring constant tension.
Liquid Level Monitoring: Provides non-contact level measurement in small tanks or vials, immune to liquid color or foam.
Robotics & AGV: Serves as a close-range collision avoidance sensor for robotic arms and Automated Guided Vehicles (AGVs) due to its fast response time (<50ms).
Material Handling: Reliable counting and positioning of objects on conveyor belts, regardless of material finish (e.g., shiny metal or transparent plastic).
