Key Features & Functionality
Robust Ultrasonic Sensing: Utilizes ultrasonic sound waves for detection, making it completely immune to optical properties. It can reliably detect virtually any material, including transparent objects (glass, plastic films), liquid levels, dark or absorbent surfaces (e.g., rubber, textiles), and highly reflective or glossy surfaces (e.g., metal, mirrors), even in the presence of dust, steam, or light mist.

Versatile Operating Modes: Supports multiple modes via teach-in configuration:

Window Mode: Defines an upper and lower limit to create a detection window.

Background Suppression: Teaches the sensor to ignore objects beyond a certain distance.

Dual Switching Outputs: This specific model features two independent PNP switching outputs (NO/NC programmable). This allows for complex tasks, such as monitoring two different level thresholds in a tank (e.g., "low level" and "empty") with a single sensor.

Potentiometer and Teach-in Configuration: Offers flexible setup through two potentiometers for coarse adjustment and a push-button teach-in function for precise and easy configuration of switching points.

Robust Metal Housing: Housed in a sturdy metal M30 housing with an IP67 protection rating, making it resistant to dust, water jets, oils, and suitable for the toughest industrial environments.

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

2. Typical Applications
Fill Level Monitoring: Single-point and multi-point level control in tanks, silos, and hoppers for liquids, powders, or granules.

Palletizing and Stack Height Control: Detecting the presence of pallets and measuring the height of stacks on conveyors or in storage systems.

Transparent Object Detection: Reliably detecting glass bottles, plastic containers, and films on packaging lines.

Loop Control (Web Sag Control): Maintaining the proper tension or sag of materials like paper, film, or textiles in processing machinery.

Object Counting and Presence Verification: Counting boxes or detecting the presence of objects on a conveyor, regardless of color.
