⚡ Why choose Ultrasonic sensor · US150?
LTCN US150 is an ultrasonic obstacle avoidance sensor for automation control, supporting multiple output interfaces.
Narrow Beam Angle Design
The emission angle is less than 8 degrees, providing better directivity for scenarios with precise detection range requirements.
Small Blind Spot Detection
The blind spot distance is only 15cm, allowing for closer obstacle detection and reducing detection dead zones.
Fast Response
The response time is 100ms, enabling rapid feedback on the presence or distance changes of target objects.
IP66 dust and water resistance
Features an IP66 protection rating, suitable for complex environments such as industrial sites and outdoor areas, with reliable dust and water resistance.
Multi-interface output
Offers multiple output models including NPN, PNP, and RS485 (Modbus), adapting to the wiring requirements of different control systems.
TEACH-IN setup
Supports TEACH-IN operation by shorting the white wire to customize the detection range of the digital output, ensuring simple operation.
LED status indication
Equipped with a green/blue dual-color LED indicator to intuitively display the object detection status and TEACH-IN learning status.
Temperature compensation function
Built-in temperature compensation function helps ensure measurement accuracy within the -25 to 70℃ operating temperature range.
📍 Applications
Mobile Robot Obstacle Avoidance
Installed on the front of mobile robots or AGVs to detect obstacles in real time, enabling automatic obstacle avoidance and path planning.
Industrial Assembly Line Detection
Deployed alongside automated assembly lines to detect the approach and presence of objects, assisting robotic arm grasping or sorting control.
Smart Parking Guidance
Used in parking lot guidance systems to detect vehicle presence, assisting with parking space status display and guidance.
AI and Automation Education
Suitable for automation teaching experiments in universities or training institutions, used for demonstrating ultrasonic ranging principles and AI application development.
