Key Features & Functionality
Miniature Ultrasonic Sensing: Utilizes ultrasonic sound waves for detection, making it immune to optical properties. It can reliably detect transparent objects (glass, plastic films), liquid levels, high-gloss or dark surfaces, and objects in dusty or foggy environments that would challenge photoelectric sensors.

Extremely Compact Size: Its very small M12 housing (12mm diameter) allows for installation in highly space-constrained applications where larger sensors cannot fit.

Short Sensing Range: Optimized for short-range applications with a 20 mm to 120 mm detection range.

Analog Output: This specific model is equipped with a 0...10 V analog output. This allows it to provide continuous distance information to a PLC or controller, making it ideal for applications like fill-level monitoring in small containers, precise proximity detection, or positioning.

Teach-in Functionality: Features a simple push-button or potentiometer teach-in method for easy configuration of the analog output range, simplifying setup and calibration.

Robust Metal Housing: Housed in a sturdy stainless steel M12 housing with an IP67 protection rating, making it resistant to dust, water jets, and suitable for harsh industrial environments, including washdown areas.

Fixed Cable Connection: The model number indicates it comes with a fixed cable for power and output signals.

2. Typical Applications
Detection of Small Containers/Bottles: Checking for the presence of small transparent vials or bottles on production lines.

Miniature Fill Level Control: Monitoring the level of liquids or granular materials in small tanks or hoppers.

Precision Proximity Sensing: Detecting the precise position of objects or parts in compact machinery.

Thread Detection: Verifying the presence of threads or thin wires.

Replacement for Capacitive Sensors: In applications where material composition varies, providing more stable detection.
