The Baumer U220.011A12D is a high-performance ultrasonic diffuse sensor designed for reliable object detection and distance measurement in demanding industrial environments. Housed in a compact M22 cylindrical brass, nickel-plated body, this sensor is ideal for applications with limited installation space. It operates on the principle of sound propagation, allowing it to accurately detect objects regardless of their color, transparency, or surface texture. The sensor features a flexible push-pull (PNP/NPN) output and a sensing range of 10 to 150 mm, making it a versatile solution for various automation tasks, including level monitoring, presence detection, and positioning.
